However, since the curtain forming device described in Patent Document 1 only moves at least one of the two sets of shape retaining pins in the depth direction, depending on the width of the curtain to be undulated, the curtain of Patent Document 1 may be used. By using the forming device, as shown in FIG. 7 and Tables 1 and 2, on the contrary, the entire shape of the curtain 1′ has been a hakama shape (a shape with a hem width larger than the upper width, see FIG. 7(a)). Or inverted trapezoidal shape (shape whose hem width is smaller than the upper width, see FIG. 7(b)) or barrel shape (shape whose width in the length direction is larger than hem width or upper width, see FIG. 7(b). ) Etc., and it becomes very uncool as a product.
Furthermore, if the curtain 1'having an entirely different shape is used for the window, it cannot be closed even if the curtain 1'is closed. However, it may not be able to sufficiently block the light entering from the window, and there is a possibility that the original function of the curtain may not be fulfilled.

Therefore, the present invention focuses on the set width ratio H1 obtained by dividing the locked curtain width W1 by the post-set extended curtain width W2, and sets the set width ratio H1 to a range of 0.20 or more. An object of the present invention is to provide a set processing machine that suppresses that the entire shape of the curtain formed into a shape is irregular such as a hakama-like shape (“suppresses the deformation of the curtain”).
Further, the present invention provides a method for manufacturing a curtain in which the entire shape is suppressed from having an irregular shape such as a hakama shape ("inhibition of curtain irregularity" is realized) by using this set processing machine. That is also the purpose.

There is a set width adjusting portion 12 capable of adjusting the curtain width direction position Ph of the pin member 11 that is locked to the ridges 3a and the valleys 3b of the folds 3 of the curtain material 2, and the set width adjusting portion 12 is in not that that have a continuous link structure 12a.

A third feature of the curtain set processing machine 10 according to the present invention is that, in addition to the above first or second feature, the continuous link structure 12a has two substantially rod-shaped links centered in the center in the longitudinal direction. A plurality of X-shaped links 12c pivotally connected to each other in a substantially X-shaped manner by a connecting shaft 12b are provided, and another X-shaped link 12c is provided at each end of the two links in the X-shaped link 12c. The end portions of the two links are pivotally connected by an end connecting shaft 12d so as to be swingable, and this is repeated, so that a plurality of the X-shaped links 12c are continuous .

A fourth feature of the curtain setting machine 10 according to the present invention is a curtain setting machine that locks the curtain material 2 and forms a fold 3 extending in the curtain length direction with respect to the locked curtain material 2. There is a set width adjusting part 12 capable of adjusting the position Ph in the curtain width direction of the pin member 11 locked to the ridges 3a and the valleys 3b of the folds 3 of the curtain material 2, and the set width adjusting part 12 is It has a bellows structure that is a plate-like member that repeats mountain folds and valley folds .

Other, set machine 10 of the curtain, the curtain fabric 2 is subjected to a heat treatment process to form the folds 3, along at least a portion of at least one side edge 2a of the curtain width direction of the curtain fabric 2 it may have a contact member 13 arranged.

Other, set machine 10 of the curtain, as the maximum width difference Dmax of width difference of the curtain width at two different curtain height direction position Pv in the curtain is 8cm or less, folds the curtain fabric 2 of the curtain 3 may be formed.

Due to these characteristics, by setting the set width ratio H1 obtained by dividing the curtain width W1 at the time of locking by the curtain width W2 at the time of extension after setting to be 0.20 or more, as compared in FIGS. 6 and 7 and Tables 1 and 2. In addition, even though the set width ratio H1 is only set to a predetermined value in the range of 0.20 or more, the entire shape of the curtain 1 processed by the set processing machine 10 (mainly expanded in the curtain width direction). The overall shape of the curtain) can be prevented from becoming irregular shapes such as hakama, inverted trapezoid, and barrel (“curtain deformation suppression”), and the original shape of the curtain can be maintained.
At the same time, since the entire shape of the curtain 1 does not have an irregular shape such as a hakama shape, even when it is used for a window or the like, it is possible to sufficiently block the light to be incident, and to perform the original function of the curtain.
The "curtain width W1 at the time of locking" in the present invention means when the curtain material 2 is locked to the set processing machine 10 and the folds 3 are about to be formed by just performing heat treatment, or the curtain material 2 Means the curtain width of the curtain material 2 (or the curtain 1 itself) when the folds 3 are actually formed.
The "curtain width W2 when extended after setting" in the present invention means the curtain width of the curtain 1 when the curtain 1 in which the folds 3 are formed on the curtain material 2 is extended in the curtain width direction by the set processing machine 10. ..
In the present invention, "when expanded in the curtain width direction (when expanded)" means that when the curtain 1 is used for the window, the curtain 1 is expanded in the curtain width direction in order to block light from the window ( This shows a state in which the curtain 1 is expanded in the curtain width direction, such as when the curtain 1 is closed (by stretching).

Further, by setting the set width ratio H1 to 0.95 or less, the curtain 1 processed by the set processing machine 10 is contracted (stored, bent) in the curtain width direction, as particularly compared in Tables 3 and 4. It becomes easier to open the curtain 1 (by shrinking), and even when the curtain 1 is opened, it is possible to further prevent the entire shape of the curtain 1 from becoming irregular shapes such as a hakama shape, an inverted trapezoidal shape, and a barrel shape. It is possible to maintain the original shape of the curtain regardless of whether the curtain 1 is opened or closed.
At the same time, since the entire shape of the curtain 1 does not have a different shape such as a hakama shape even when it is opened and closed, even when it is used for a window or the like, it is possible to sufficiently take in light or block light when necessary. It is possible to achieve the original function of the curtain.

Further, by having the set width adjusting portion 12 capable of adjusting the curtain width direction position Ph of the pin member 11 which is locked to the ridges 3a and the valleys 3b of the folds 3, the curtain width of the curtain 1 which is locked to the set processing machine 10 is set. It is possible to set at the position Ph in the curtain width direction of the pin member 11 according to the above, and one set processing machine 10 can form the folds 3 on the curtain material 2 at the most suitable set width ratio H1 for each curtain 1 to be set.
As a result, it is possible to prevent any type of curtain 1 from having an irregular shape such as a hakama shape (it is possible to realize "suppression of various curtain irregular shapes").
It should be noted that, regardless of the value of the set width ratio H1, it is only necessary to have the set width adjusting portion 12 capable of adjusting the position Ph in the curtain width direction of the pin member 11 that is locked to the ridges 3a and the valleys 3b of the folds 3, and thus various curtain variants It can be said that this can be realized.

The formation of the folds 3 on the curtain material 2 is performed by heat treatment, and the contact member 13 is set by arranging the contact member 13 along a part or all of the side edge 2a of the curtain material 2. It serves as a heat insulating material that suppresses heat transfer inside and outside the processing machine 10 (controls that the heated heat escapes from the inside to the outside and the heat flows from the outside to the inside during cooling). The formation efficiency of can be improved. Further, the abutting member 13 makes it possible to suppress the rebound of the ears 1a of the curtain 1, which greatly contributes to the suppression of the barrel-shaped deformation of the curtain 1.
The "heat treatment process" in the present invention means a process of applying dry hot air (dry heat type) to the curtain material 2 or a process of applying heated steam (wet heat type). Any process may be used as long as the folds 3 can be formed on the curtain fabric 2 by heat, such as a process of applying a (thermal iron).
Further, by forming the folds 3 on the curtain material 2 so that the maximum width difference Dmax among the width differences of the curtain widths at the two different curtain height direction positions Pv of the curtain 1 is 8 cm or less, the set processing machine 10 It is possible to prevent the entire shape of the curtain 1 processed by the process from becoming an irregular shape (“curtain deformation suppression”), and the original function of the curtain can be achieved.
The “curtain width” in the present invention means the width (length in the left-right direction) of the curtain 1 or the curtain material 2 itself when the curtain 1 or the curtain material 2 is expanded, and the curtain 1 or the curtain material 2 shrinks. The width (length in the left-right direction) of the curtain 1 or the curtain material 2 when viewed from the front when stored (stored, bent, shrunk) may be included.

The curtain manufacturing method according to the present invention uses the curtain set processing machine 1 for locking the curtain material 2 and forming the folds 3 extending in the curtain length direction with respect to the locked curtain material 2. The curtain width W1 at the time of locking the curtain material 2 in the set processing machine 1 is extended in the curtain width direction by the curtain in which the folds 3 are formed on the curtain material 2 in the set processing machine 1. The set width ratio H1 divided by the curtain width W2 at the time of stretching after setting when set is 0.20 or more.

<Curtain 1>
As shown in FIG. 1,4～6, Curtain 1, or used in a window for functionalizing and design imparting such shielding vision, shielding, heat shielding, UV cut dimming, lighting soundproofing It is used as a wall or partition.
The curtain 1 may have any configuration as long as it is used for a window or the like, but it has a fold 3 formed on the curtain material 2 and/or has a curtain width at two different curtain length direction positions Pv. The maximum width difference Dmax may be 8 cm (8.0 cm) or less.
In the present invention, “and/or” means at least one of them, and in the above case, the case has only the folds 3, and the maximum width difference Dmax is only 8.0 cm or less. , The case with folds 3 and the maximum width difference Dmax is 8.0 cm or less.

The curtain 1 may be used for a window or the like and opened/closed in a horizontal direction (also referred to as a left-right direction or a curtain width direction) H while being folded in a wave shape.
In this case, the curtain 1 may have a curtain hook that suspends the entire curtain 1 by being locked to a curtain runner that is movable along the curtain rails on the upper part of the window frame. The number of curtain hooks is not particularly limited, but is usually plural.

The curtain 1 may have a fold 3 (also referred to as a drape curtain) or may have other configurations as long as the maximum width difference Dmax is 8.0 cm or less. If it is opened/closed to H, double-opening with one curtain provided on each of the left and right sides (both ends in the curtain width direction) of one window or one-opening with one curtain 1 provided for one window, etc. It is also possible to use a lace curtain or the like.
Other than that, the curtain 1 is like a plain shade (Roman shade) that opens and closes while folding the curtain 1 in a vertical direction (also referred to as a vertical direction and a curtain length direction) V in a substantially wavy shape, or performs vertical opening and closing and left and right opening and closing at the same time. It may be one.

In addition, the curtain 1 is like a pleated screen in which a plurality of plate-like fabrics extending in the curtain width direction H are continuous in the curtain length direction V and are folded and folded in the curtain length direction V in a wavy manner. Is also good.
Besides the above, the curtain 1 may be like a panel screen that opens and closes the panel in which the curtain material 2 is stretched in the curtain width direction H.

The shape, size, pattern, color, thickness, basis weight, and bending resistance of the curtain 1 are not particularly limited, but, for example, regarding the shape, depending on the shape of the window (window frame) used, etc. The shape may be substantially rectangular as viewed from the front, or may be substantially circular or triangular as well.
The size of the curtain 1 is also not particularly limited, but may be, for example, a curtain length L and a curtain width W according to the size of the window or the like used as long as it is substantially rectangular in a front view.

More specifically, the curtain length L of the curtain 1 may be any value as long as it corresponds to the window or the like used. For example, for a sweep window, 120 cm or more and 240 cm or less, preferably 140 cm It may be 220 cm or less and more preferably 160 cm or more and 200 cm or less (180 cm or the like).
In addition to this, the curtain length L of the curtain 1 is, for example, 60 cm or more and 180 cm or less, preferably 80 cm or more and 160 cm or less, and more preferably 100 cm or more and 140 cm for high waist windows (waist windows) or when used as a cafe curtain. It may be the following (120 cm or the like), and for a small window or the like, it may be, for example, 40 cm or more and 100 cm or less, preferably 50 cm or more and 90 cm or less, and more preferably 60 cm or more and 80 cm or less (70 cm or the like).

The curtain width W of the curtain 1 may be any value as long as it corresponds to the window used, for example, 70 cm or more and 100 cm or less if it is used in both sides with respect to a sweep window or waist high window (waist window). , Preferably 75 cm or more and 95 cm or less, more preferably 80 cm or more and 90 cm or less (85 cm or the like), and if it is one-sided with respect to a sweep window or waist high window (waist window), 140 cm or more and 200 cm or less, preferably It may be 150 cm or more and 190 cm or less, and more preferably 160 cm or more and 180 cm or less (170 cm or the like).
In addition to this, the curtain width W of the curtain 1 is, for example, 30 cm or more and 60 cm or less, preferably 35 cm or more and 55 cm or less, and more preferably 40 cm or more and 50 cm or less (45 cm or the like), if it is used for both sides of a small window. The size may be, for example, 60 cm or more and 120 cm or less, preferably 70 cm or more and 110 cm or less, and more preferably 80 cm or more and 100 cm or less (90 cm or the like) as long as it is one-sided with respect to a small window or the like.

<Curtain width W at position Pv in the curtain length direction>
Although various shapes and sizes have been described so far as shown in FIGS. 1 and 4 to 6, the curtain 1 may have any shape such as a substantially rectangular shape or a substantially circular shape, and the curtain length L and the curtain width W. Is a predetermined value, the curtain width W has any value at any (any) curtain length direction position Pv (also referred to as a vertical position or a height position).
As long as the curtain length L is a predetermined value, the curtain width W at the curtain length direction position Pv exists at a plurality of positions, and the curtain width W at two different (two positions) curtain length direction positions Pv is measured. You can also do it. That is, there are some width differences D of the curtain width W at the two different curtain height direction positions Pv.

<Maximum difference in curtain width Dmax>
As shown in FIGS. 1, 4 to 6, of the several width differences D of the curtain width W, of course, the largest value (this is the maximum width difference Dmax) exists, and this maximum width difference Dmax. Can also be said to be a value obtained by subtracting the smallest curtain width (minimum curtain width) Wmin from the largest curtain width (maximum curtain width) Wmax at all curtain length direction positions Pv when the curtain 1 is extended.
Therefore, as the maximum width difference Dmax is smaller (such as 8.0 cm or less), for example, if the overall shape of the curtain 1 is a hakama shape (the hem width Wc is larger than the upper width Wb), the hem width Wc and the upper width are larger. The difference in Wb can be made small, and even if the shape is an inverted trapezoid (shape in which the hem width Wc is smaller than the upper width Wb), the difference between the hem width Wc and the upper width Wb is small and the barrel shape (the hem width Wc or the upper width Wb is smaller than , The curtain width W in the middle of the curtain length direction V is large), the difference between the curtain width W in the middle and the hem width Wc or the upper width Wb can be made small, so that the degree of irregularity is suppressed. Can be said to be

The "upper width Wb" in the present invention is the curtain width of the upper portion 1b (2b) of the curtain 1 (or the curtain material 2) at the time of extension.
The "hem width Wc" in the present invention is the curtain width of the lower portion (hem portion) 1c (2c) of the curtain 1 (or the curtain material 2) when stretched.

The maximum width difference Dmax is 8.0 cm or less, but may be 5.0 cm or less, and more preferably 3.0 cm or less.
In this way, by setting the maximum width difference Dmax to be at least 8.0 cm or less among the width differences D of the curtain widths W at the two different curtain height direction positions Pv, the overall shape of the curtain 1 is different such as a hakama shape. The shape can be suppressed (“curtain deformation suppression”) and the original shape of the curtain can be maintained.
Even when the curtain 1 is used as a window or the like, the light can be sufficiently taken in when the curtain 1 is opened, and the light can be firmly blocked when the curtain 1 is closed, so that the original function of the curtain can be sufficiently fulfilled.

In addition, the curtain 1 has its pattern, color (color tone/saturation/brightness), thickness, and basis weight. These can be said to be the pattern, color, thickness, and basis weight of the curtain fabric 2 itself. I will explain in detail.
The curtain 1 may be sewn with sewn folds 3'to be described later. The thread to be sewn (sewing thread) is not particularly limited, and may be colorless and transparent or white. The color may have the same color tone, saturation, and lightness as the curtain fabric 2, or conversely, different color tone, saturation, and lightness, which may be part of the design.

<Bending width flexibility G>
As shown in FIGS. 1, 4 to 6, before the folds 3 are formed by the above-described set processing machine 10 or the like (that is, the lateral bending softness) G in the curtain width direction H of the curtain 1 (that is, , Before the set processing), the folds 3 are formed by the heat treatment of the set processing machine 10 or the like, as well as including the bending resistance (curve before the setting) G1 in the curtain width direction H. Also, the bending resistance in the curtain width direction H after the setting (that is, the setting curtain 1) (lateral bending rigidity after setting) G2 is included.
There is no particular limitation on the specific values of the bending resistance G (lateral bending rigidity before setting G1 and bending rigidity after setting G2), but for example, it is based on the A method of JIS-L-1096:2010. For example, the lower limit may be 30 (30.0) mm or more, preferably 40.0 mm or more, and more preferably 50.0 mm or more (33.8 mm, 55.5 mm) as long as it has a bending resistance. , 71.8 mm, 91.3 mm, 95.7 mm, 110.8 mm, etc.). The upper limit of the bending resistance G is also not particularly limited, but is, for example, 120.0 mm or less, preferably 100.0 mm or less, more preferably 90.0 mm or less (33.8 mm, 55.5 mm, 71.8 mm). , 91.3 mm, 95.7 mm, 110.8 mm, etc.).

In addition, the value of the "flexibility according to JIS-L-1096:2010 method A" in the present invention includes the flexibility measured according to JIS-L-1096:2010 method A. Of course, it also includes the bending resistance measured by applying the method A of JIS-L-1096:2010.
By setting the lateral stiffness G to be 30.0 mm or more, for example, when the folds 3 (particularly, the folds 3 extending in the curtain length direction V) are formed on the curtain material 2, the folds 3 that have been once formed are used. The shape of the folds is suppressed, the edge (shape) of the folds 3 can be secured, and the curtain 1 itself can be made to have a waist.

Further, naturally, the bending resistance of the curtain 1 also includes the bending resistance in the curtain length direction V (so-called vertical bending resistance) G′, and this bending resistance G′ also includes the above-described set processing machine 10 and the like. The bending softness (vertical bending softness before setting) G1′ in the curtain length direction V of the curtain material 2 before the folds 3 are formed (that is, before the setting processing) and the heat treatment by the setting processing machine 10 or the like. The bending resistance G2′ after forming the folds 3 (that is, after setting processing) (post-setting vertical bending resistance) G2′ is also included.
The specific values of such longitudinal bending softness G'(vertical bending softness G1' before setting, vertical bending softness G2' after setting) are also not particularly limited. For example, the lower limit value is JIS-L. The bending resistance may be 30.0 mm or more, preferably 40.0 mm or more, and more preferably 50.0 mm or more as long as it has a bending resistance according to the A method of -1096:2010. The upper limit of the longitudinal bending softness G′ is also not particularly limited, but may be, for example, 120.0 mm or less, preferably 100.0 mm or less, more preferably 90.0 mm or less.

<Curtain fabric 2>
As shown in FIGS. 1 and 4 to 6, the curtain fabric 2 is a sheet-like fabric that is a base of the curtain 1, and the folds 3 may be formed on the curtain fabric 2 or the sewing folds 3′ may be sewn. It is a thing.
The curtain material 2 is not only the material before the folds 3 are formed and the sewn folds 3′ are sewn, but also those after the sewn folds 3′ are once sewn and the sewn folds 3′ etc. are removed. Including.
The curtain material 2 may be any material as long as the folds 3 can be formed and the sewn folds 3'can be sewn. For example, a woven fabric, a knitted fabric (lace), a sheet-shaped material such as a film, Is also good.

When the curtain fabric 2 is a woven fabric, it may have any woven structure, but may be, for example, a plain weave, a twill weave, a satin weave, a double weave, or a multiple weave of double or more weaves.
When the curtain material 2 is a knitted fabric, warp knitting such as denby knitting (tricot knitting), raschel knitting, double raschel knitting, bandadike knitting (atlas knitting), cord knitting, plain knitting (textile knitting), rubber knitting (rib knitting) ), weft knitting such as pearl knitting, and the like.

When the curtain fabric 2 is a woven fabric or a knitted fabric, the fibers constituting (woven or knit) the polyester fabric such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), etc. Polyolefin fibers such as nylon (polyamide) fiber, polyethylene (PE) and polypropylene (PP), rayon fiber, cupra fiber, acetate fiber, acrylic fiber containing polyacrylonitrile (PAN) as a main component, polyvinyl alcohol (PVA) fiber (Vinylon fibers), synthetic fibers such as polyurethane (PU) fibers, glass fibers, wool, silk, and the like, and these may be used alone or in combination.
If the fibers forming the curtain material 2 which is a woven or knitted fabric are thermoplastic synthetic fibers including the above-mentioned polyethylene terephthalate (PET), the texture is obtained by the heat treatment process (set process) of the heat treatment section 21 described later. It is easy to form the folds 3 without damaging the folds, the shape of the folds 3 once formed can be suppressed, and the edge (shape) of the folds 3 can be secured. , It can be said that the sharpness of the set mold can be made effective.

When the curtain material 2 is a woven fabric or a knitted fabric, the fineness of the fibers forming (woven or knitting) them may be any value, but for example, the total fineness is 20 dtex or more and 3000 dtex or less.
Furthermore, when the curtain fabric 2 is a woven or knitted fabric, depending on the fabric width (100 cm, 150 cm, 200 cm, 300 cm, etc.) of the loom or knitting machine, a plurality of fabrics may be spliced (width spanning (width spanning)). ) One curtain fabric 2 may be configured. Further, the curtain material 2 may be used by changing its length and width.
The curtain width W of the curtain material 2 (width in the curtain width direction H after width joining (width joining)) may be any value as long as it corresponds to the window to be used, etc. Since it depends on whether or not the edge 2a (ear 1a) is sewn, the details will be described later.

If the curtain material 2 is a sheet-like material such as a film (when the curtain 1 is, for example, a shower curtain), the constituent materials thereof are polyvinyl chloride (PVC) resin, polyethylene terephthalate (PET), Polyresin such as polytrimethylene terephthalate (PTT) and polybutylene terephthalate (PBT), synthetic resin such as polyamide (PA) resin, and the like, or these may be used alone or in combination.
Even if the material forming the curtain material 2 which is a sheet-like material is a synthetic resin such as the above-mentioned polyvinyl chloride (PVC) resin, the heat treatment of the heat treatment section 21 is performed as in the case of a woven fabric or a knitted fabric. It can be said that the processing (set processing) facilitates the formation of the folds 3, suppresses the deformation of the folds, and secures the edge (shape), and can bring out the sharpness of the set type.
If desired, the curtain material 2 described above may be added with an extender pigment or filler (filler) such as titanium oxide or calcium carbonate, or may be a deodorant, an antibacterial agent, an antifungal agent, a flame retardant, a water repellent, A material to which an antifouling agent, a coloring agent, a fragrance, a foaming agent, or the like is added may be used, or the curtain material 2 may be treated and then treated.

The curtain fabric 2 may have any pattern such as a pattern of plants such as flowers and vegetation, an animal pattern, a geometric pattern, a plain pattern, or a pattern of surface irregularities. The color of the curtain material 2 may be any color tone such as red, orange, yellow, green, blue, violet, black, and white, and any value may be used for saturation and brightness. .
Further, when the curtain fabric 2 is formed with the folds 3 by the above-described set processing machine 10, even if a patch member 13 described later is arranged along at least one side edge 2a in the curtain width direction H. good.

It can be said that the curtain cloth 2 does not need to have the folds 3 or the sewn folds 3 ′ provided that the maximum width difference Dmax of the curtain 1 formed on the basis of the curtain fabric 2 is 8.0 cm or less. ..
In the following description, it is assumed that the folds 3 are formed and the sewn folds 3'are sewn on the curtain material 2.

<Fold 3>
As shown in FIGS. 1 and 4 to 6, the folds 3 are formed on the curtain material 2 described above and extend (along) the curtain length direction V in the curtain 1, and can also be referred to as vertical folds 3.
The vertical folds 3 are deformed so that the curtain material 2 itself moves back and forth in the depth direction (also known as the front-back direction, the thickness direction, and the curtain depth direction) T, and as a whole forms a substantially wavy shape (zigzag) in a plan view. is doing.

That is, the vertical folds 3 extend in the curtain length direction V as well as the ridges 3a extending (along) in the curtain length direction V at every predetermined fold spacing S in the curtain width direction H along the surface of the curtain material 2. While having the valleys 3b alternately, they exist adjacent to each other in the curtain width direction H over the entire curtain 1.
When the curtain 1 is used as a window or the like, the portion protruding toward the front of the curtain 1 is the mountain 3a of the vertical fold 3, and the portion retracted toward the depth is the valley 3b of the vertical fold 3. It can be said that there is.

The ridges 3a of the vertical folds 3 are formed such that the portion protruding toward the front side is formed over a part or the whole of the curtain length direction V, and the valleys 3b of the vertical folds 3 are portions retracted toward the depth side. Will be formed over a part or the whole of the curtain length direction V.
The fold spacing S between the ridges 3a and the valleys 3b in the vertical folds 3 is not particularly limited, but is, for example, 2 cm or more and 15 cm or less, preferably 3 cm or more and 12 cm or less, and more preferably 4 cm or more and 10 cm. The following (about 6 cm, etc.) may be used.
The number of vertical folds 3 for one curtain material 2 is not particularly limited, but is usually plural.

Note that folds other than the vertical folds 3 may be provided, for example, the folds may extend in the curtain width direction H (horizontal folds).
In this case, the lateral folds are similar to the vertical folds 3 in that the curtain material 2 itself is deformed so as to move back and forth in the curtain depth direction T, but the point that the lateral folds form a substantially wavy shape (zigzag) in side view, Different from vertical folds 3. At this time, the bending resistance G′ of the curtain 1 in the curtain length direction V may be 30.0 mm or more.

<Sewing folds 3'>
As shown in FIGS. 1 and 4 to 6, the sewn folds 3 ′ are formed by sewing the curtain material 2 described above and extend (along) the curtain length direction V in the curtain 1, which is a vertical sewn fold. It can be said to be 3'.
The vertical stitches 3'are folded several times such that the upper portion 2b of the curtain material 2 in the curtain length direction V (also referred to as the upper portion 1b of the curtain 1) and the like are moved back and forth in the curtain depth direction T by a predetermined stitch width. It is formed by sewing the unfinished state.

The shape of the vertical stitches 3'provided on the curtain material 2 is not particularly limited, but may be, for example, one mountain stitch fold, two mountain stitch folds, three mountain stitch folds, single folds, or box folds. ..
The vertically sewn folds 3'folded and sewn in this way are formed at predetermined intervals of sewn folds S'on the curtain material 2, and when the curtain 1 is used for a window or the like, the vertically sewn folds 3'are sewn. However, in the plan view, the protrusions are repeatedly present in the curtain width direction H over the entire curtain 1 while protruding toward the front side for each sewn fold interval S′.

As described above, when the upper part 2b of the curtain fabric 2 is folded and sewn, the vertical stitches 3'is downward in the folding line direction (the same direction as the curtain length direction V) of the vertical stitches 3'. The vertical folds 3 described above may be formed along the line (that is, the curtain width direction position Ph of the vertical stitches 3′ and the curtain width direction position Ph of the vertical folds 3 may substantially match).
At this time, the valleys 3b of the vertical folds 3 described above may be located below the vertical stitches 3', and at the same time, an intermediate position in the curtain width direction H between two adjacent vertical stitches 3'. However, the mountain 3a of the vertical fold 3 described above may be used.
On the contrary, the mountain 3a of the vertical pleats 3 may be located below the vertical stitches 3', and at the same time, the intermediate position in the curtain width direction H between two adjacent vertical stitches 3'is The valley 3b of the vertical fold 3 may be used.

It should be noted that what is sewn as the sewn folds 3'is not only the upper portion 2b of the curtain fabric 2 but also the upper portion 2b of the curtain length direction V to a midway portion, the entire curtain length direction V, or the curtain length direction. It may be only the middle part of V or only the lower part (hem part) 2c (also referred to as the hem part 1c of the curtain 1).
The above-mentioned stitch crease spacing S'in the longitudinal stitch fold 3'is not particularly limited in its specific value, but for example, 5 cm or more and 30 cm or less, preferably 7 cm or more and 25 cm or less, and more preferably 10 cm or more and 20 cm or less (12 0.5 cm) may be used.
The number of vertical stitches 3'for one curtain material 2 is not particularly limited, but is usually plural.

Note that folds other than the vertical stitches 3'may be provided, and for example, the stitch folds may be stitch folds extending in the curtain width direction H (side stitches).
In this case, the side stitches are sewn in such a manner that the side end portion of the curtain cloth 2 in the curtain width direction H is folded back and forth several times in the curtain depth direction T by a predetermined stitch fold length L'. This is different from the vertical fold 3 in that it is formed.

<Curtain width W3 when stretched with stitches>
As shown in Figs. 1 and 4, the "extended curtain width W3 with stitched folds" in the present invention refers to the curtain 1 obtained by sewing the above-mentioned curtain material 2 with stitched folds 3'(longitudinal stitch folds 3'). Means the curtain width W of the curtain 1 when expanded in the curtain width direction H.
In addition, "when extended in the curtain width direction H" in the extended curtain width W3 with sewing folds, as described above, when the curtain 1 is used for the window, in order to block light from the window, When the curtain 1 sewn with the sewn folds 3'is expanded (extended) in the curtain width direction H and the curtain 1 is closed, the curtain 1 sewn with the sewn folds 3'is expanded in the curtain width direction H. Represents

If the sewn folds 3'are sewn in the stretched curtain width W3 with sewn folds, the curtain cloth 2 before the folds 3 are formed by the above set processing machine 10 (that is, before the set processing) is performed. Not only including the curtain width (curtain width when stretched with pre-set sewing folds) W3′, but also after the folds 3 have been formed by heat treatment by the set processing machine 10 (that is, the curtain 1 after set processing) Curtain width (curtain width when stretched with stitches after setting) W3" is also included.
The stretched curtain width W3 with sewing folds is not particularly limited in its value, but may be, for example, substantially the same as the curtain width W of the curtain 1 described above, specifically, 70 cm or more and 100 cm or less, preferably It may be 75 cm or more and 95 cm or less, more preferably 80 cm or more and 90 cm or less (85 cm or the like), or 140 cm or more and 200 cm or less, preferably 150 cm or more and 190 cm or less, and more preferably 160 cm or more and 180 cm or less (170 cm or the like).
In addition, the stretched curtain width W3 with sewing folds is, for example, 30 cm or more and 60 cm or less, preferably 35 cm or more and 55 cm or less, more preferably 40 cm or more and 50 cm or less (45 cm or the like), or 60 cm or more and 120 cm or less, preferably 70 cm. It may be 110 cm or more, and more preferably 80 cm or more and 100 cm or less (90 cm or the like).

<Width of stretched fabric W4>
As shown in FIGS. 1 and 4, the “extended cloth width W4” in the present invention means the curtain when the curtain cloth 2 before the sewing folds 3′ are sewn in the curtain width direction H. Not only the curtain width W of the cloth 2, but also the curtain width W when the curtain cloth 2 after the sewing folds 3'are sewn and the sewing folds 3'are removed in the curtain width direction H Including.
In addition, "when stretched in the curtain width direction H" in the stretched fabric width W4 represents a state in which the curtain fabric 2 in which the sewn folds 3'are not sewn is expanded in the curtain width direction H. Further, it can be said that the stretched cloth width W4 is the total splicing width when the curtain cloth 2 is spliced (pitch spliced).

If the sewn folds 3'are not sewn in the stretched fabric width W4, the curtain width of the curtain fabric 2 before the folds 3 are formed by the above-described set processing machine 10 (that is, before set processing) ( In addition to including the pre-set stretched fabric width W4′, the curtain width after the folds 3 are formed by heat treatment such as the set processing machine 10 (that is, the curtain 1 after the set processing) (after the set) The width of the stretched fabric W4" is also included.
The stretched fabric width W4 is not particularly limited in its value, for example, 70 cm or more and 400 cm or less, preferably 75 cm or more and 380 cm or less, more preferably 80 cm or more and 360 cm or less (170 cm or the like), or 140 cm or more and 800 cm or less, It may be preferably 150 cm or more and 760 cm or less, and more preferably 160 cm or more and 720 cm or less (340 cm or the like).
In addition, the stretched fabric width W4 is, for example, 30 cm or more and 240 cm or less, preferably 35 cm or more and 220 cm or less, more preferably 40 cm or more and 200 cm or less (90 cm or the like), or 60 cm or more and 480 cm or less, preferably 70 cm or more and 440 cm or less. More preferably, it may be 80 cm or more and 400 cm or less (180 cm or the like).

<Sewing fold width ratio H2>
The "sewing fold width ratio H2" in the present invention is a ratio (value) obtained by dividing the above-mentioned "extended curtain width W3 with sewing folds" by "extended cloth width W4".
The sewing fold width ratio H2 is not particularly limited, but is, for example, 1.0 or more and 3.0 or less, preferably 1.2 or more and 2.7 or less, and more preferably 1.4 or more and 2.4 or less (1. 5, 2.0, 2.5, etc.).

As described above, by setting the sewn fold width ratio H2 to 1.0 or more and 3.0 or less, even if the curtain material 2 having a predetermined width is used, the curtain 1 is used according to the width of the window or the like in which the curtain 1 is used. The curtain width of 1 can be adjusted, and at the same time, as a curtain product, for example, a gorgeous atmosphere to a natural wave can be expressed.
Incidentally, it is preferable to calculate the sewing fold width ratio H2 based on the stretched curtain width W3 with stitched folds and the stretched cloth width W4 both before and after the set process.

<Side edge 2a of curtain material 2 and upper part 2b, hem 2c>
The sewn folds 3′ described so far are formed by sewing, but the parts other than the sewn folds 3′ (the side edges 2a and the upper portion 2b of the curtain material 2 and the hem 2c (the ears 1a and the upper portion 1b of the curtain 1 are formed. , The portion which becomes the hem 1c)) may also be formed by sewing.
The following is an example in the order of sewing.

With respect to the curtain material 2 which has been width-jointed (width-jointed), an interlining material (made of polyester or the like) is sewn to the upper end of the upper portion (upper portion in the curtain length direction V) 2b, and the curtain material 2 is wrapped so as to wrap the interlining material. Fold back the upper part 2b several times (a few times). It may be folded once, or may be finished by heat cutting or overlocking without folding.
The upper portion 2b of the curtain material 2 (the upper portion 1b of the curtain 1) is formed by stitching the folded back portion and the wrapped cloth with the curtain material 2 itself. In addition, interlining is not necessarily used for forming the upper portion 2b (upper portion 1b).

Next, each side edge 2a of the curtain material 2 having the upper portion 2b in the curtain width direction H is folded back several times (two or three times). It may be folded once, or may be finished by heat cutting or overlocking without folding.
The folded back portion and the curtain material 2 themselves are sewn together to form the side edge 2a of the curtain material 2 (the ear portion 1a of the curtain 1).

After that, the sewn folds (vertical sewn folds, etc.) 3'described above are formed on the curtain material 2 having the side edges 2a.
Finally, the hem part (lower part) 2c of the curtain material 2 having the sewn folds 3'in the curtain length direction V is folded back several times (two or three times). It may be folded once, or may be finished by heat cutting or overlocking without folding.
The folded back portion and the curtain material 2 itself are sewn together to form the hem portion 2c of the curtain material 2 (the hem portion 1c of the curtain 1).

<Pin member 11>
As shown in FIGS. 1 to 5, in the set processing machine 10, the pin member 11 is locked to the ridges 3a and the valleys 3b of the folds 3 of the curtain material 2 described above.
In the present invention, "the pin member 11 is locked to the ridges 3a and the valleys 3b of the folds 3" means that after the folds 3 are formed on the curtain material 2 by the set processing machine 10, the ridges 3a and the valleys of the folds 3 are formed. In order to form the folds 3 on the curtain material 2 by the set processing machine 10 in addition to the engagement with the ridges 3b, the curtain material 2 is locked on the portions which will later become the ridges 3a and valleys 3b of the folds 3. Including what you are doing.

The number of pin members 11 in one set processing machine 10 is not particularly limited, like the number of folds (vertical folds) 3, but is usually a plurality.
The pin member 11 may be provided in any of the set processing machines 10 as long as it can be engaged with the ridges 3a and the valleys 3b to form the folds 3 on the curtain material 2. It may be provided in the lower portion 10c of the inside, and in this case, the pin member 11 is locked to the lower portion 2c of the curtain material 2.

In addition, the pin member 11 may be provided in the middle or an upper portion of the curtain length direction V in the set processing machine 10.
The planar arrangement of the pin member 11 is similar to the shape of the ridges 3a and the valleys 3b of the folds 3 in the curtain 1 in plan view, and when the curtain 1 is used for a window or the like, the ridges 3a of the folds 3 protruding toward the front side. The pin member 11 (mountain pin member 11a) that is locked from the back side 1B of the curtain 1 (the back side 2B of the curtain material 2), and the front side 1A (curtain material 2 of the curtain 1 in the valley 3b of the fold 3 that is retracted to the depth side. The pin member 11 (valley pin member 11b) that is locked from the front side 2A) is provided side by side in a substantially wavy shape in a plan view. Further, the folded back portion of the ear portion 1a of the curtain 1 (the side edge 2a of the curtain material 2) may be inserted into the outermost pin member 11 in the curtain width direction H (the outermost right and left sides).

The direction in which the pin members 11 are arranged is substantially the same as the curtain width direction H of the curtain material 2 on which the folds 3 are formed.
There are three types of distances (pin intervals) S″ between the pin members 11 arranged in the curtain width direction as described above. Interval Sa", the second is the distance between the valley pin members 11b adjacent to each other in the curtain width direction H, the valley pin interval Sb", and the third is the mountain pin member that is adjacent to the curtain width direction H diagonally. The distance between 11a and the trough pin member 11b is the trough pin interval Sab″.

The pin member 11 may have any configuration as long as it can be locked to the ridges 3a and the valleys 3b of the folds 3, but, for example, in the lower part of the set processing machine 10 or the like, the pin member 11 is substantially in the curtain length direction (vertical direction). Mountains 3a and valleys 3b are locked to the pillar material itself erected along with it, or a cylindrical material (paper tube, etc.) is covered on the pillar material that is erected (cover the pillar material so that the pillar material passes through it). The peaks 3a and the valleys 3b may be locked to this tubular material.
The cross-sectional shape of these pin members 11 (pillar material, tubular material) is not particularly limited, but may be, for example, a substantially circular shape, or may be a substantially elliptical shape, a substantially rectangular shape, or a substantially triangular shape.

As another configuration of the pin member 11, the above-mentioned pillar material and the tubular material may be mixed, and for example, the cylindrical material (that is, the larger pin member 11) is locked to the ridge 3a of the fold 3. A columnar member (that is, a pin member 11 having a smaller size) may be locked in the valley 3b of the fold 3, or vice versa.
In addition, the pin member 11 may be composed of only a pillar material or a cylinder material, and the diameter thereof may be two or more.

The diameter of the pin member 11 (the diameter of the substantially cylindrical material or the diameter of the substantially cylindrical material) is also not particularly limited, but is, for example, 0.5 cm or more and 10.0 cm or less, preferably 1.0 cm or more and 9.0 cm or less, More preferably, it may be 1.5 cm or more and 8.0 cm or less.
The length of the pin member 11 (for example, the height standing upright from the lower part in the set processing machine 10) is also not particularly limited, but is, for example, 5 cm or more and 40 cm or less, preferably 10 cm or more and 35 cm or less, and more preferably 15 cm or more. It may be 30 cm or less.

The pin spacing S″ may be adjustable by the set width adjusting unit 12 described later, but may be a fixed value if the set width ratio H1 described below is 0.20 or more. (That is, even in the set processing machine 10 in which the position Ph in the curtain width direction of the pin member 11 cannot be adjusted).
Of the three types of pin spacing S″, when the mountain pin spacing Sa″ has a fixed value, the value is not particularly limited, and may be substantially the same as the value of the valley pin spacing Sb″, For example, it may be 4 cm or more and 22 cm or less, preferably 6 cm or more and 18 cm or less, and more preferably 8 cm or more and 14 cm or less (10 cm or the like).

Of the three types of pin spacing S″, when the valley pin spacing Sb″ has a fixed value, similarly, there is no particular limitation on the value and it is substantially the same as the value of the mountain pin spacing Sa″. It may be 4 cm or more and 22 cm or less, preferably 6 cm or more and 18 cm or less, and more preferably 8 cm or more and 14 cm or less (10 cm or the like).
The same applies to the case where the mountain-valley pin spacing Sab" has a fixed value among the three types of pin spacing S", and there is no particular limitation on the value, and for example, 5 cm or more and 31 cm or less, preferably 8 cm or more and 25 cm or less, It may be preferably 11 cm or more and 20 cm or less (14 cm or the like).

<Set width adjustment unit 12>
As shown in FIGS. 1 to 5, the set width adjusting unit 12 is capable of adjusting the position (also referred to as the left and right position) Ph of the pin member 11 in the curtain width direction.
The set width adjusting unit 12 may be provided in any of the set processing machines 10 as long as the position Ph in the curtain width direction of the pin member 11 can be adjusted. It may be provided in the lower part 10c in the processing machine 10, or may be provided in the middle part of the curtain length direction V or in the upper part in the set processing machine 10 according to the position of the pin member 11.

<Continuous link structure 12a>
The set width adjusting portion 12 may have any configuration as long as it can adjust the position Ph in the curtain width direction of the pin member 11, but may have a continuous link structure 12a as shown in FIGS. good.
The continuous link structure 12a is provided with a plurality of X-shaped links 12c in which substantially central portions in the longitudinal direction of two substantially rod-shaped links are pivotally connected to each other by a central connecting shaft 12b so as to be swingable in an approximately X shape. The ends of the two links of the other X-shaped link 12c are pivotally connected to the ends of the two links of the X-shaped link 12c so as to be swingable by the end connecting shafts 12d. Repeatedly, a plurality of X-shaped links 12c are continuously formed.

The continuous link structure 12a is formed by connecting the plurality of X-shaped links 12c described above, so that each of the two links of each X-shaped link 12c is rotated around the central connecting shaft 12b. The structure 12a as a whole expands and contracts (expands and contracts).
The expansion and contraction direction of the continuous link structure 12a is substantially the same as the curtain width direction H of the curtain material 2 on which the folds 3 are formed.

As long as the set width adjusting unit 12 can adjust the curtain width direction position Ph of the pin member 11, the above-described pin member 11 may be provided in any part of the continuous link structure 12a, for example, Alternatively, one end of the support member 12e may be attached to the central connecting shaft 12b of each X-shaped link 12c, and the pin member 11 may be erected on the other end of the support member 12e.
In this way, by providing the pin member 11 on the substantially rod-shaped support member 12e attached to the central connecting shaft 12b, the continuous link structure 12a expands and contracts in the curtain width direction H, and the position Ph of the pin member 11 in the curtain width direction Ph. The position Pt of the pin member 11 in the curtain depth direction (also referred to as the front-back position) does not change even if the position changes (freely while maintaining the position Pt of the curtain depth direction adjusted by the set depth adjustment unit 22 described later). The position Ph in the curtain width direction can be adjusted).

In the connecting link structure 12a, the through holes 12f penetrating the midway portion in the longitudinal direction of each support member 12e in the same direction as the expansion and contraction direction, or the connecting link structures 12a as a whole connecting the through holes 12f in the curtain width direction H. You may have the guide member 12g when expanding/contracting along.
The set width adjusting unit 12 may have only one continuous link structure 12a or two continuous link structures 12a described above.

<When there are two continuous link structures 12a>
As shown in FIGS. 4 and 5, when the set width adjusting portion 12 has two continuous link structures 12a, for example, the curtain width direction position Ph of the mountain pin member 11a is set to one continuous link structure ( The mountain side continuous link structure) 12a' may be adjusted, and the curtain width direction position Ph of the valley pin member 11b may be adjusted by the other continuous link structure (valley side continuous link structure) 12a".
At this time, one of the mountain side supporting member 12e′ of the mountain side continuous link structure 12a′ and the valley side supporting member 12e″ of the valley side continuous link structure 12a″ is longer than the other (for example, the valley side supporting member 12e″ is on the mountain side. It may be longer than the support member 12e').

By changing the lengths of the two support members 12e′ and 12e″ in this manner, even if the mountain pin member 11a and the valley pin member 11b are brought close to each other in the set depth adjusting unit 22 described later, the mountain side support member 12e′ and the valley are The peak-side continuous link structure 12a′ and the valley-side continuous link structure 12a″ can be closer to each other by the difference in the lengths of the side support members 12e″ without contacting each other.
Moreover, since the mountain pin member 11a and the valley pin member 11b are alternately arranged in a substantially corrugated (zigzag) manner, the mountain pin member 11a provided in the mountain side continuous link structure 12a′ and the valley side continuous link structure 12a″ are formed. The provided valley pin members 11b have their curtain width-direction positions Ph displaced from each other by about a half cycle of the pin spacing S″ (peak pin spacing Sa″ or valley pin spacing Sb″) described above.

More specifically, the approximately half cycle of the pin spacing S″ corresponds to the difference between the curtain width direction position Ph of the central connecting shaft 12b of each X-shaped link 12c and the curtain width direction position Ph of the end connecting shaft 12d. To do.
If the mountain pin spacing Sa″ and the valley pin spacing Sb″ are substantially the same, the intermediate position in the curtain width direction H between the adjacent mountain pin members 11a is closest to these two mountain pin members 11a. Are substantially the same as the curtain width direction positions Ph of the valley pin members 11b facing each other, and at the same time, an intermediate position in the curtain width direction H between the adjacent valley pin members 11b is closest to and opposes these two valley pin members 11b. It is substantially the same as the position Ph in the curtain width direction of the mountain pin member 11a.

Therefore, in one of the mountain-side continuous link structure 12a′ and the valley-side continuous link structure 12a″, the central connecting shaft 12b located at the center in the expansion/contraction direction has the curtain width direction of the set width adjusting unit 12 (set processing machine 10). Located in the center of H.
In FIGS. 4 and 5, the valley-side continuous link structure 12a″ includes a central connecting shaft 12b located at the center in the expansion/contraction direction and a support member (valley-side central supporting member) 12e″ attached to the central connecting shaft 12b. It is fixed at a central position in the curtain width direction H with respect to the width adjusting unit 12 (set processing machine 10).

On the other hand, in the continuous link structure 12a on the opposite side (mountain side continuous link structure 12a' in FIGS. 4 and 5), the Z-shaped link 12c, not the X-shaped link 12c, is provided at the substantially central position in the expansion/contraction direction. The mold link 12h exists.
The substantially Z-shaped link 12h is a pair of left and right support members 12e (mountain side support members 12e' in FIGS. 4 and 5) and diagonally arranged between the left and right support members 12e. 12e and each end portion are constituted by a substantially rod-shaped link (having substantially the same length as the link of the X-shaped link 12c) pivotally connected by each end connecting shaft 12d so as to be swingable.

Two links (having a length of about half) of the X-shaped links 12c are pivotally supported by a central connecting shaft 12b so as to be swingable to the left and right support members 12e of the substantially Z-shaped links 12h. A plurality of X-shaped links 12c are continuous outward in the left-right direction in the curtain width direction H.
The link between the two support members 12e in the substantially Z-shaped link 12h is arranged substantially parallel to any one of the X-shaped links 12c adjacent to the left and right of the support member 12e, and the intermediate portion in the length direction of the link. Is pivotally connected to the set width adjusting unit 12 (set processing machine 10) so as to be swingable at a central position in the curtain width direction H.

The set width adjusting unit 12 having such two continuous link mechanisms 12a (the mountain side continuous link mechanism 12a′ and the valley side continuous link mechanism 12a″) engages the curtain material 2 (particularly, the hem 2c) with the pin member 11. Any structure may be used as long as it can be stopped. For example, the curtain material 2 hung (hanged) between the mountain side continuous link mechanism 12a′ and the valley side continuous link mechanism 12a″ (in particular, as shown in FIG. 4). In addition, the curtain material 2 (particularly the hem portion 2c) is arranged from the front and the rear along the curtain depth direction T to the ten fabric material 2 with respect to the hem portion 2c which is arranged substantially straight along the curtain width direction H in a plan view. The pin members 11 (mountain pin members 11a, valley pin members 11b) are pressed (contacted and sandwiched), and the mountain pin members 11a are locked to the portions of the curtain material 2 that become the ridges 3a of the folds 3, The valley pin member 11b may be engaged with the portion that becomes the valley 3b of the fold 3 (see FIGS. 4 and 5).
The pressing of the pin members 11 (the mountain pin members 11a and the valley pin members 11b) against the curtain material 2 may be performed by the set depth adjusting unit 22 described later, or by another mechanism.

Thus, by pressing the mountain pin member 11a and the valley pin member 11b from the front and back against the curtain material 2 (hem 2c) that is substantially straight in a plan view, the mountain pin member 11a and the valley in the set processing machine 10 are pressed. The pin member 11b is easily locked to the ridges 3a and the valleys 3b of the folds 3 of the curtain material 2, and the work efficiency is improved.
In addition, the set width adjusting unit 12 does not press the curtain material 2 of the pin member 11 and instead of the mountain pin member 11a and the valley pin member 11b which are alternately arranged in a substantially corrugated shape (zigzag), the hem portion of the curtain material 2 is 2c may be configured to be locked in a substantially waveform (zigzag).

<When there is one continuous link structure 12a>
On the other hand, the set width adjusting unit 12 may have only one continuous link structure 12a described above, and in that case, as described above, it is attached to the central connecting shaft 12b of each X-shaped link 12c. The supporting pin (first supporting member) 12e is provided with either the mountain pin member 11a or the valley pin member 11b.
The other of the mountain pin member 11a and the valley pin member 11b may be provided, for example, on a second support member (not shown) attached to the end connecting shaft 12d of each X-shaped link 12c.

At this time, if the second support member or the first support member 12e is configured to expand and contract in the curtain depth direction T, the curtain of the mountain pin member 11a and the valley pin member 11b while adjusting the curtain width direction position Ph. The distance in the depth direction T can be kept constant.
The second support member described above is attached to either the front side or the back side in the curtain depth direction T of the two end connecting shafts 12d in each X-shaped link 12c. A second through hole (not shown) may be provided in the middle portion of the second supporting member in the longitudinal direction, and a second guide member communicating with the second through hole may be provided.
The drive source 12M for expanding and contracting the one or two continuous link structures 12a described so far is not particularly limited, but, for example, a drive force from a motor or the like is transmitted via a chain, a pulley, or the like. The position Ph of the pin member 11 in the curtain width direction may be adjusted by expanding and contracting the continuous link structure 12a or directly expanding and contracting the continuous link structure 12a by a cylinder mechanism.

In the case of the continuous link structure 12a described so far, the pin distance S″ between the adjacent pin members 11 expands and contracts according to the expansion and contraction of the entire continuous link structure 12a, and any pin distance S″ is the same.
On the other hand, the set width adjusting unit 12 may be configured to be able to adjust the pin spacing S″ to different values for each adjacent pin member 11, which will be described in detail below.

<bellows structure, screw structure, etc.>
The set width adjusting unit 12 may have a bellows structure (also called an accordion structure, a bellows, a flexible structure, etc.) that is a plate-shaped member that repeats mountain folds and valley folds.
The bellows structure may have any cross-sectional shape, for example, a substantially circular shape (a generally cylindrical shape as a whole), a substantially rectangular shape (a generally square tube shape as a whole), or a substantially triangular shape (a whole shape). May have a substantially triangular shape) and other polygonal shapes.

The material of the bellows structure is not particularly limited, but may be, for example, synthetic resin, metal, cloth, paper or the like.
The set width adjusting unit 12 may adjust the curtain width direction position Ph of the pin member 11 by providing the pin member 11 on the supporting member attached to the mountain fold portion or the valley fold portion in the bellows structure.

The set width adjusting unit 12 may have one or two bellows structures, and in the case of one, a support member provided with the mountain pin member 11a and a support member provided with the valley pin member 11b are provided. Alternately, attach to the mountain folds or valley folds in the bellows structure.
When the set width adjusting part 12 has two bellows structures, a bellows structure having a support member provided with the mountain pin members 11a and a bellows structure having a support member provided with the valley pin members 11b are installed. , So that the pin members 11 face each other alternately.

In addition, the set width adjusting unit 12 causes a plurality of female screw members to be screwed into a substantially cylindrical male screw member extending in the curtain width direction H, and the female pin members 11a and 11a via the supporting member. A screw structure in which the valley pin members 11b are alternately provided may be used.
The support member having this screw structure alternately protrudes from the male screw member toward the front side and the depth side along the curtain depth direction T, or from the male screw member along the curtain depth direction T toward the front side or the depth side in the same direction. You may make it protrude and it may arrange|position the long and short support members by turns.

In addition to this, the set width adjusting portion 12 is detachably attached to a substantially rod-shaped guide member extending in the curtain width direction H by a clip-like holding portion provided on a support member of the pin member 11, so that the pin member 11 can be attached. The position Ph in the curtain width direction may be adjusted.
The expansion/contraction width of the set width adjusting unit 12 is not particularly limited, but may be, for example, 125 cm or more and 245 cm or less, preferably 145 cm or more and 225 cm or less, and more preferably 165 cm or more and 205 cm or less (185 cm or the like). .

The distance (maximum width) from the pin member 11 at the left end to the pin member 11 at the right end when the set width adjusting unit 12 is most extended in the curtain width direction H is also not particularly limited, but is, for example, 270 cm or more and 390 cm or less, preferably May be 290 cm or more and 370 cm or less, more preferably 310 cm or more and 350 cm or less (333 cm or the like).
The distance (minimum width) from the pin member 11 at the left end to the pin member 11 at the right end when the set width adjusting unit 12 is most shrunk (stored, bent, shrunk) in the curtain width direction H is also not particularly limited. For example, it may be 90 cm or more and 210 cm or less, preferably 110 cm or more and 190 cm or less, and more preferably 130 cm or more and 170 cm or less (148 cm or the like).

  The curtain material 2 to be locked by the set processing machine 10 having the set width adjusting unit 12 described so far has the curtain width W2 (when the curtain 1 that has become a product is expanded when the curtain material 2 is stretched after setting after the folds 3 are formed. It can be said that the value of the curtain width W1 at the time of locking can be arbitrarily adjusted (changed) with respect to the value of the curtain width W).

Therefore, it is possible to set at the position Ph in the curtain width direction of the pin member 11 according to the curtain width W of the curtain 1 that is locked to the set processing machine 10, and one set processing machine 10 is most suitable for each curtain 1 to be set. The folds 3 can be formed on the curtain material 2 with the set width ratio H1.
As a result, it is possible to prevent any type of curtain 1 from having an irregular shape such as a hakama shape (it is possible to realize "suppression of various curtain irregular shapes").
It should be noted that, regardless of the value of the set width ratio H1, it is only necessary to have the set width adjusting portion 12 capable of adjusting the position Ph in the curtain width direction of the pin member 11 that is locked to the ridges 3a and the valleys 3b of the folds 3, and thus various curtain variants It can be said that it is possible to realize the suppression of degeneration.

<Curtain width W1 when locked>
As shown in FIGS. 1 and 4 to 6, the “curtain width at the time of locking (locking width) W1” in the present invention means that the curtain material 2 is locked to the set processing machine 10 and the heat treatment is performed exactly as described above. When the folds 3 are formed by processing or the like (that is, when the set processing is attempted), or when the folds 3 are actually formed on the curtain material 2 (that is, when the set processing is actually performed) The curtain width of the curtain material 2 (or the curtain 1 itself) is meant.
The "when locked in the curtain width direction H" in the locked curtain width W1 means that the pin member 11 of the set processing machine 10 has the ridges 3a and valleys 3b of the folds 3 in the curtain material 2 as described above. It shows a state in which (the part that becomes) is locked in a substantially waveform (zigzag) in a plan view.

Further, the curtain width W1 at the time of locking is formed before the crease 3 is actually formed by the set processing machine 10 (that is, before the set processing) if the curtain material 2 is locked by the set processing machine 10. It does not matter whether it is after (that is, after set processing).
The curtain width W1 at the time of locking is the curtain of the curtain material 2 before the sewing folds 3'described above are sewn or when the curtain material 2 from which the sewing folds 3'are removed is stretched in the curtain width direction H. In addition to including the width (curtain width when the sewing folds are not locked) W1′, the curtain width after the sewing folds 3′ are sewn (the curtain width when locking with the sewing folds) W1″ is also included.

The value of the curtain width W1 at the time of locking is not particularly limited, but is, for example, 21 cm or more and 400 cm or less, preferably 22 cm or more and 380 cm or less, more preferably 24 cm or more and 360 cm or less (51 cm, 85 cm, 119 cm, etc.), It may be 42 cm or more and 800 cm or less, preferably 45 cm or more and 760 cm or less, and more preferably 48 cm or more and 720 cm or less (102 cm, 170 cm, 238 cm, etc.).
In addition, the curtain width W1 during locking is, for example, 9 cm or more and 240 cm or less, preferably 10 cm or more and 220 cm or less, more preferably 12 cm or more and 200 cm or less (27 cm, 45 cm, 63 cm, etc.), or 18 cm or more and 480 cm or less, preferably May be 21 cm or more and 440 cm or less, more preferably 24 cm or more and 400 cm or less (54 cm, 90 cm, 126 cm, etc.).

<Curtain width W2 when extended after setting>
As shown in FIGS. 1 to 6, the “curtain width W2 during stretching after setting” in the present invention means that the curtain 1 in which the folds 3 are formed on the curtain material 2 is stretched in the curtain width direction by the above-described set processing machine 10. It means the curtain width of that curtain 1 at the time.
In addition, when the curtain 1 is used for the window, the "when the curtain 1 is used for the window" in the curtain width W2 during extension after setting means that the curtain 1 is moved in the curtain width direction in order to block light from the window. When the curtain 1 is expanded (stretched) and closed, the curtain 1 is expanded in the curtain width direction.

If the folds 3 are formed on the curtain material 2 by the set processing machine 10 in the curtain width W2 during extension after setting, before the above-mentioned sewing folds 3′ are sewn or the sewing folds 3′ are sewn. The curtain width of the curtain 1 when the curtain 1 is removed in the curtain width direction H (curtain width when the stretched folds are not stretched after setting after setting) W2′ is included, and after the folds 3′ are sewn. Curtain width (curtain width when stretched with creases after setting) W2" is also included.
The stretched curtain width W2 after setting is not particularly limited in its value, for example, 70 cm or more and 400 cm or less, preferably 75 cm or more and 380 cm or less, more preferably 80 cm or more and 360 cm or less (170 cm or the like), or 140 cm or more and 800 cm or more. The following may be preferably 150 cm or more and 760 cm or less, more preferably 160 cm or more and 720 cm or less (340 cm or the like).
In addition, the curtain width W2 during stretching after setting is, for example, 30 cm or more and 240 cm or less, preferably 35 cm or more and 220 cm or less, more preferably 40 cm or more and 200 cm or less (90 cm or the like), or 60 cm or more and 480 cm or less, preferably 70 cm or more. It may be 440 cm or less, more preferably 80 cm or more and 400 cm or less (180 cm or the like).

<Set width ratio H1>
The "set width ratio H1" in the present invention is a ratio (value) obtained by dividing the above-mentioned "locking curtain width W1" by the "post-setting extended curtain width W2".
The lower limit of the set width ratio H1 is 0.20 or more, preferably 0.23 or more, more preferably 0.30 or more (0.23, 0.237, 0.30, 0.34, 0.40, 0.50, 0.70, 0.95, etc.).

The set width ratio H1 may be arbitrarily adjusted (changed) by the set width adjusting unit 12 of the set processing machine 10 within the range described above, but provisionally, the pin interval S″ of the pin members 11 in the set processing machine 10 will be described. Even when the fixed width is fixed, the set width ratio H1 when the curtain material 2 is locked to the fixed pin member 11 may be within the above range.
As a result, as compared with FIGS. 6 and 7 and Tables 1 and 2, the set width ratio H1 is set to a predetermined value in the range of 0.20 or more, but is processed by the set processing machine 10. It is possible to prevent the entire shape of the curtain 1 (mainly the overall shape when it is stretched in the curtain width direction) from becoming a different shape such as a hakama shape, an inverted trapezoid shape, or a barrel shape. Suppression”), the original shape of the curtain can be maintained.

At the same time, since the entire shape of the curtain 1 does not have an irregular shape such as a hakama shape, even when it is used for a window or the like, it is possible to sufficiently block the light to be incident, and to perform the original function of the curtain.
The set width ratio H1 may have an upper limit value, which is not particularly limited, but is, for example, 0.95 or less, preferably 0.825 or less, more preferably 0.70 or less (0 .23, 0.237, 0.30, 0.34, 0.40, 0.50, 0.70, 0.95).

By setting the set width ratio H1 to 0.95 or less in this way, the curtain 1 processed by the set processing machine 10 is contracted in the curtain width direction (stored, as shown in Tables 3 and 4). It becomes easier to open the curtain 1 (bending or shrinking), and even when the curtain 1 is opened, it is possible to further suppress the entire shape of the curtain 1 from being irregularly shaped such as a hakama shape, an inverted trapezoidal shape, or a barrel shape. Further suppression of deformation"), the original shape of the curtain can be maintained regardless of whether the curtain 1 is opened or closed.
At the same time, since the entire shape of the curtain 1 does not become a different shape such as a hakama when it is opened and closed, even when it is used for a window or the like, it is possible to sufficiently take in light or block light when necessary. It is possible to achieve the original function of the curtain.
In addition, it is preferable to calculate the set width ratio H1 based on the curtain width W1 at the time of locking and the curtain width W2 at the time of stretching after setting after considering the presence or absence of the seam folds 3'.

<Abutting member 13>
As shown in FIGS. 1 to 4, the padding member 13 is arranged along the side edge 2 a of the curtain material 2 locked by the set processing machine 10, and partitions the inside and outside of the set processing machine 10. It can be said that it is a partition member.
The patch member 13 may be arranged along at least one side edge 2a of the curtain material 2 in the curtain width direction H (in other words, the patch member 13 may be the left edge 2a of the curtain material 2 and/or the patch member 13). Or arranged along the right edge 2a).

Further, the abutting member 13 may be arranged along the entire side edge 2a of the curtain fabric 2 over the curtain length direction V, and at a part of the side edge 2a in the curtain length direction V. It may be arranged along.
The abutting member 13 is not particularly limited in its configuration as long as it can be arranged along the side edge 2a of the curtain material 2, but may be, for example, a substantially plate-shaped (plate-shaped) or a substantially sheet-shaped member. The shape may also be uniformly flat, or the lower portion in the curtain length direction may be curved outward in the curtain width direction.

The patch member 13 may be hung in the set processing machine 10 along the side edge 2a of the curtain material 2 or attached to the set processing machine 10, for example.
When the folds 3 are formed on the curtain material 2 by heat treatment in the heat treatment section 21 or the like to be described later by such a contact member 13, heat is transferred to the contact member 13 inside and outside the set processing machine 10. (It suppresses the heat that is heated escapes from the inside to the outside and that the heat flows from the outside to the inside at the time of cooling), and improves the efficiency of forming the folds 3 by heat treatment.
Further, the abutting member 13 makes it possible to suppress the rebound of the ears 1a of the curtain 1, which greatly contributes to the suppression of the barrel-shaped deformation of the curtain 1.

<Heat treatment part 21>
As shown in FIGS. 1 to 4, the heat treatment section 21 heat-treats the curtain material 2 locked by the set processing machine 10.
The “heat treatment process” in the present invention means a process of applying dry hot air (dry heat type) or a process of applying heated steam (wet heat type) to the curtain fabric 2, and in addition to this, a trowel (heat Any process may be used as long as the folds 3 can be formed on the curtain material 2 by heat, such as a process of applying a trowel.

When the folds 3 are formed by heat treatment, the material of the curtain fabric 2 is a woven fabric or knitted fabric made of synthetic fibers (thermoplastic synthetic fibers) such as the above-mentioned polyethylene terephthalate (PET), polyethylene terephthalate (PET), etc. A sheet-like material made of the synthetic resin (thermoplastic synthetic resin) is preferable.
The following mainly describes a case where hot air is applied to the curtain material 2.

The heat treatment unit 21 may have any configuration as long as it can perform heat treatment processing on the curtain material 2. For example, if the heat treatment unit 21 is the dry heat type processing described above, the hot air generator 21a and this hot air generation are provided. A blower path 21b for sending hot air from the machine 21a to the set processing machine 10, a storage case 21c for temporarily collecting the hot air from the blower path 21b, and an ejection hole for ejecting the hot air from the storage case 21c to a lower portion 10c in the set processing machine 10 21d may be included.
The temperature of the hot air applied to the curtain material 2 is not particularly limited, but may be, for example, 100° C. or higher and 130° C. or lower, or 100° C. or higher and 150° C. or lower. It does not matter if the temperature is higher or 180° C. which is a higher temperature.

On the other hand, the heat treatment section 21 may have a steam generator 21e that mixes steam from a midway part of the air passage 21b as long as it is wet heat processing.
In addition, the heat treatment unit 21 may have a partition that surrounds the lower portion (skirt portion) 2c of the curtain material 2 in the set processing machine 10.

<Set depth adjustment unit 22>
As shown in FIGS. 1 to 4, the set depth adjustment unit 22 is capable of adjusting the curtain depth direction position (also referred to as the front-back position) Pt of the pin member 11 described above.
The set depth adjusting unit 22 may be provided in any of the set processing machines 10 as long as the position Pt of the pin member 11 in the curtain depth direction can be adjusted. It may be provided in the lower part 10c in the processing machine 10, or may be provided in the middle part of the curtain length direction V or in the upper part in the set processing machine 10 according to the position of the pin member 11.

The set depth adjusting unit 22 may have any configuration as long as the position Pt of the pin member 11 in the curtain depth direction can be adjusted, but a member that supports the mountain pin member 11a and the valley pin member 11b described above (for example, described above. Of the continuous link structure 12a or the like in the set width adjusting unit 12 or a frame that does not have the function of adjusting the position Ph in the curtain width direction), either the mountain side or the valley side is moved along the curtain depth direction T. It may be configured to allow it.
The drive source for such movement is not particularly limited, but may be manual. For example, a cylinder mechanism may directly move the member that supports the pin member 11 in the curtain depth direction T, or drive from a motor or the like. A member that supports the pin member 11 may be moved in the curtain depth direction T by transmitting force through a chain, a pulley, or the like.

When the set depth adjusting unit 22 moves the continuous link structure 12a or the like in the set width adjusting unit 12 described above as a member supporting the pin member 11 in the curtain depth direction T, the set processing machine 10 causes the pin member 11 to move. It is possible to simultaneously adjust the curtain depth direction position Pt and the curtain width direction position Ph.
When the set depth adjusting unit 22 moves a frame or the like having no function of adjusting the curtain width direction position Ph in the curtain depth direction T as a member that supports the pin member 11, the set processing machine 10 Only the curtain depth direction position Pt of the pin member 11 can be adjusted.

<Hanging part 23>
As shown in FIGS. 1 to 4, the hanging portion 23 suspends the curtain material 2 locked in the set processing machine 10.
The hanging portion 23 has a member for hanging the curtain material 2 (curtain runner, curtain hook, etc.), and is provided in the upper portion 10b in the set processing machine 10.

The hanging portion 23 may have any other configuration as long as the curtain material 2 can be hung, but may have, for example, the above-described continuous link structure 12a (upper continuous link structure).
When the hanging portion 23 has an upper continuous link structure, this upper continuous link structure also has a plurality of central connecting shafts of the X-shaped link, and a hanging member capable of suspending the curtain hook on the central connecting shaft ( A member having a through hole for hanging the curtain hook) may be attached to the tip of the substantially rod-shaped member.

Since the hanging portion 23 has the upper continuous link structure, the position Ph in the curtain width direction of the hanging member can be adjusted even in the upper portion of the curtain material 2.
The drive source 23M for expanding and contracting such an upper continuous link structure is also not particularly limited, but similarly to the set width adjusting unit 12, for example, a driving force from a motor or the like is transmitted via a chain, a pulley, or the like. Then, the upper continuous link structure may be expanded or contracted, or the upper continuous link structure may be expanded or contracted directly by a cylinder mechanism to adjust the curtain width direction position Ph of the pin member 11.

In addition, the hanging part 23 has a curtain runner for hanging the curtain hook of the curtain material 2 and a curtain rail for movably mounting the curtain runner, or the entire hanging part 23 or a part of the hanging part 23 is a curtain length. You may have the raising/lowering mechanism 25 which raises/lowers in a direction. Further, by independently raising and lowering the plurality of hanging portions 23, it becomes possible to simultaneously set and process the curtain fabrics 23 having different curtain lengths L (form the folds 3 on the curtain fabric 2).
The lifting mechanism 25 described above may have any configuration as long as it can lift the entire hanging part 23 or a part of the hanging part 23 in the curtain length direction. For example, the lifting function 25 includes the following three frames 25a, It may have 25b and 25c.

In detail, the elevating mechanism 25 includes a large frame 25a having the above-mentioned pin member 11 and the set width adjusting portion 12 at the bottom, and a size smaller than the large frame 25a in plan view (curtain width direction H of the large frame 25a. Is smaller than the length of the large frame 25a and has a depth smaller than the length of the large frame 25a in the curtain depth direction T, and a further round of the middle frame 25b (narrower than the length of the middle frame 25b in the curtain width direction H). The depth is smaller than the length of the middle frame 25b in the curtain depth direction T).
Further, the elevating mechanism 25 elevates and lowers the small frame 25c with respect to the middle frame 25b, and elevates and lowers the middle frame 25b with respect to the large frame 25a. It may be provided with a lifting drive source 25d by transmitting (see FIGS. 2 and 3).

The size of the large frame 25a is not particularly limited, but for example, the length (frame width) in the curtain width direction H is 380 cm or more and 500 cm or less, preferably 400 cm or more and 480 cm or less, and more preferably 420 cm or more and 460 cm. It may be the following (440 cm or the like).

The length may be 420 cm or less (400 cm or the like), and the size of the small frame 25c is not particularly limited. For example, the length (frame width) in the curtain width direction H is 285 cm or more and 405 cm or less, preferably May be 305 cm or more and 385 cm or less, and more preferably 325 cm or more and 365 cm or less (346 cm or the like).

The lifting width (stretching width) of the lifting mechanism 25 is not particularly limited, but may be, for example, 170 cm or more and 290 cm or less, preferably 190 cm or more and 270 cm or less, and more preferably 210 cm or more and 250 cm or less (230 cm or the like).
The distance (maximum height) from the lower end of the pin member 11 to the hanging portion 23 when the elevating mechanism 25 is most extended in the curtain length direction V is also not particularly limited, but is, for example, 290 cm or more and 410 cm or less, preferably 310 cm or more. It may be 390 cm or less, more preferably 330 cm or more and 370 cm or less (350 cm or the like).

The distance (minimum height) from the lower end of the pin member 11 to the hanging portion 23 when the elevating mechanism 25 is most contracted in the curtain length direction V is also not particularly limited, but is, for example, 60 cm or more and 180 cm or less, preferably 80 cm or more. It may be 160 cm or less, more preferably 100 cm or more and 140 cm or less (120 cm or the like).
The hanging part 23 may be the continuous link structure 12a used for the set width adjusting part 12 to respond to the expansion and contraction of the continuous link structure 12a used for the set width adjusting part 12, but the hanging part 23 and the continuous link structure 12a may be used. Or the continuous link structure 12a is not used for the hanging part 23 in the first place, the set width adjusting part 12 can be expanded and contracted independently of the hanging part 23, and the curtain hook in the hanging part 23 can freely move in the curtain width direction H. The upper width Wb and the hem width Wc of the curtain 1 can be independently changed, which is preferable.

<Cover part 24>
As shown in FIGS. 1 to 4, the cover portion 24 shields at least one opening of the set processing machine 10.
The cover portion 24 may have any configuration as long as it can shield the opening of the set processing machine 10, but may be, for example, a sheet (sheet-like material).

As such a sheet, the cover portion 24 may include a tuck-up type shielding sheet, a winding type shielding sheet, and/or a side opening sheet.
Even with such a cover 24, it is possible to prevent heat from moving from the opening of the set processing machine 10 (to prevent heated heat from escaping from the inside to the outside, or from flowing from the outside to the inside during cooling). ), the efficiency of formation of the folds 3 by heat treatment can be improved.

<Test 1 (shape test when stretched)>
Examples 1-1 to 1-6, Examples 2-1 to 2-3, Examples 3-1 to 3-4, Examples 4-1 to 4-3, Examples 5-1 to 5- described above. 4, the curtains of Examples 6-1 to 6-7, Comparative Examples 1 to 3 and Concrete Example 1 were stretched, and the upper width Wb and the hem width Wc of these curtains stretched and the upper width Wb- The hem width Wc (value obtained by subtracting the hem width Wc from the upper width Wb) is shown in Tables 1 and 2 below.
In Test 1, the largest curtain width (maximum curtain width) Wmax is the upper width Wb or the hem width Wc, and the smallest curtain width (minimum curtain width) in all of these examples, comparative examples, and specific examples. Wmin was the upper width Wb or the hem width Wc which is not the maximum curtain width Wmax.

Examples 1-1 to 1-6, Examples 2-1 to 2-3, Examples 3-1 to 3-4, and Comparative Examples 1 to 3 are shown in Table 1, and Examples 4-1 to 4- Table 2 shows 3, Example 5-1 to 5-4, Example 6-1 to 6-7, and Specific Example 1.
In addition, the evaluation in Tables 1 and 2 (evaluation of the shape when stretched) is "x" when the absolute value of the upper width Wb-hem width Wc is "greater than 8.0 cm", and "greater than 3.0 cm," When it was "8.0 cm or less", it was marked as "○", and when it was "3.0 cm or less", it was marked as "A".

<Evaluation of Test 1 (evaluation of shape when stretched)>
As shown in Tables 1 and 2, in consideration of Comparative Examples 1 to 3 in which the set width ratio H1 is "less than 0.20", the values of the upper width Wb-the bottom width Wc are "+15.5 cm" and "+9". 0.5 cm", "+13.0 cm", the hem width Wc is about 10 cm or more wider than the upper width Wb, and the entire curtain when stretched has a very hakama shape, and when used for windows, etc. Can not be closed even when closed (because it has a hakama shape and the hem width is larger than the upper width, so even if the hem side is closed, it is vacant in the upper left and right and in the center) , The original function of the curtain cannot be fulfilled.
However, just by setting the set width ratio H1 to "0.20 or more", the absolute value of the upper width Wb-hem width Wc must be "8 cm" regardless of the bending resistance G and the crease ratio H2. Or less" (that is, the absolute value of the upper width Wb-the bottom width Wc falls within "8 cm or less", which means that the maximum width difference Dmax is also 8 cm or less).

Further, the curtain 1 of Examples 3-2, 5-1, 6-3 in which the set width ratio H1 is "0.23", and Example 2-2 in which the set width ratio H1 is "0.237", Even though the curtain 1 of 4-1 has various stiffness G (33.8 mm, 55.5 mm, 71.8 mm, 91.3 mm, 95.7 mm), their upper width Wb-hem width The value of Wc is "+2.5 cm", "+3.0 cm", "+2.0 cm", "+4.5 cm", "+4.0 cm", or the like, which is a very small value of "5 cm or less", which is almost rectangular. It has a shape (the original shape of the curtain) and can fully fulfill the original function of the curtain.
Therefore, if the set width ratio H1 is set to "0.23 or more", the absolute value of the upper width Wb to the hem width Wc can be set to "5 cm or less" even for curtains having various bending resistances G. Therefore, the preferable lower limit value of the set width ratio H1 is “0.23 or more”.

Furthermore, the curtain 1 of Example 1-3 in which the set width ratio H1 is “0.30” and the curtain 1 of Example 1-5 in which the set width ratio H1 is “0.34” are very large ( Even if the hardness is (hard) G (110.8 mm), the values of these upper width Wb-hem width Wc are very small at "+1.5 cm" and "-2.0 cm", and are substantially rectangular. Yes, these can also fully fulfill the original function of the curtain.
That is, if the set width ratio H1 is set to "0.30 or more", the absolute value of the upper width Wb to the hem width Wc is set to "5 cm or less" or "3 cm or less" even for a curtain having a large bending resistance G. The lower limit value of the set width ratio H1 is more preferably "0.30 or more".

Then, collecting examples in which the absolute value of upper width Wb-hem width Wc is "3 cm or less", examples 1-2, 1-3, 1-5, 2-3, 3-1 to 3-3. -3, 4-2, 4-3, 5-1 to 5-3, 6-1 to 6-4, 6-7, and the values of the upper width Wb-the bottom width Wc are "+2.5 cm" and "+1". .5 cm", "-2.0 cm", "-1.0 cm", "+1.0 cm", "+2.5 cm", "-1.0 cm", "+1.0 cm", "+2.0 cm", ""+3.0cm","+1.0cm","-2.0cm","+2.0cm","-0.5cm","+2.0cm","-2.0cm","+3.0cm" Although the values are very small in many examples, these bending resistances G are all types (110.8 mm, 95.7 mm, 91.3 mm, 71.8 mm, 55.5 mm, 33.8 mm). Also, the sewing fold width ratio H2 and all types (1.5, 2.0, 2.5) cover all types, and it is suitable for any curtain having a bending resistance G and a sewing fold ratio H2. If the folds 3 are formed on the curtain material 2 with the set width ratio H1 (when set), the absolute value of the upper width Wb-hem width Wc is "3 cm or less", which is a very rectangular shape, and the original function of the curtain is sufficient. It can be set and processed into a curtain that can fulfill all needs.
At that time, it does not matter whether the pin member 11 in the set processing machine 10 is fixed or the position Ph in the curtain width direction is adjusted by the set width adjusting unit 12.

Of the examples in which the absolute value of these upper width Wb-hem width Wc is "3 cm or less", the largest stitch fold width ratio H2 is 11 "2.0", and then 4 ". 1.5" followed by two "2.5".
Therefore, if the sewing fold width ratio H2 is set to around “2.0” (that is, preferably 1.2 or more and 2.7 or less, more preferably 1.4 or more and 2.4 or less), the upper width Wb− It can be said that the absolute value of the hem width Wc tends to be small.

On the other hand, collecting Examples and the like in which the absolute value of the upper width Wb-the hem width Wc is “greater than 3 cm and 8 cm or less”, Examples 1-1, 1-4, 1-6, 2-1, 2-2, 3-4, 5-4, 6-3, 6-5, 6-6, and the values of the upper width Wb-the bottom width Wc are "+5.0 cm", "-4.0 cm", and "-". 7.0 cm", "+6.0 cm", "+4.5 cm", "-6.0 cm", "-7.0 cm", "+4.5 cm", "-4.0 cm", "+6.0 cm". However, among these, the most common stiffness G is 3 "110.8 mm" and "33.8 mm", then 2 "95.7 mm" and 1 "91.3 mm". "And "55.5 mm", and the bending resistance G is "71.8 mm", the absolute value of the upper width Wb-hem width Wc was not "greater than 3 cm and 8 cm or less".
Therefore, the bending resistance G is around “71.8 mm” (that is, the lower limit value of the bending resistance G is preferably 40.0 mm or more, more preferably 50.0 mm or more, as described above, or If the upper limit of G is preferably 100.0 mm or less, more preferably 90.0 mm or less), it can be said that the absolute value of the upper width Wb-the bottom width Wc tends to be small.
In addition, in the specific example 1 in Table 2, the value of the upper width Wb-the bottom width Wc is "+4.5 cm", and only the absolute value of the upper width Wb-the bottom width Wc (that is, the maximum width difference Dmax) is calculated. since it is a "8cm or less" if you look at, it can be said that an example in which concretely represent Curtain 1 (example).

<Test 2 (Ease of storage, shape test when stored)>
Examples 1-1 to 1-6, Examples 2-1 to 2-3, Examples 3-1 to 3-4, Examples 4-1 to 4-3, Examples 5-1 to 5- described above. 4, half of the upper width Wb when the curtains of Examples 6-1 to 6-7, Comparative Examples 1 to 3 and Concrete Example 1 were stretched (1/2 of the upper width Wb when stretched). ), the upper width Wb' and the hem width Wc' of the curtain when stored in the curtain width direction H (when stored), the upper width Wb' of the storage-the hem width Wc' (the upper width Wb' of the storage The value obtained by subtracting the hem width Wc' at time), and (1/2 of the upper width Wb at the time of extension)-the upper width Wb' at the time of storage (from 1/2 of the upper width Wb at the time of storage, The values obtained by subtracting the upper width Wb' are shown in Tables 3 and 4 below.
As for (1/2 of upper width Wb when extended)-upper width Wb' when stored, the upper width Wb of the curtain when extended corresponding to the state where the window is closed by the curtain is half (1/2). Since it can be said that it corresponds to the state where the curtain is opened, the closer the upper width Wb' when stored is to this value (1/2 of the upper width Wb when extended), or (the upper width when extended) The smaller the upper width Wb' when stored than the value of 1/2) of the width Wb, the easier the curtain is to open (easy to store).

In Test 2 as well, in all of the examples, comparative examples, and specific examples, the largest stored curtain width (also referred to as the maximum curtain width Wmax) is the upper width Wb' or the hem width Wc at the time of storage, and the smallest storage time. The curtain width (also referred to as the minimum curtain width Wmin) was the upper width Wb' or the hem width Wc' at the time of storage that is not the largest curtain width at the time of storage.
Here, "when stored in the curtain width direction H (when stored)" in the present invention means that when a curtain is used in the window, the curtain is contracted in the curtain width direction H in order to take in light from the window. When the curtain is opened (bent or shrunk), the curtain is contracted in the curtain width direction H. It does not matter whether a fastener such as a tassels is used.

Further, the "upper width Wb' during storage" in the present invention is the curtain width of the upper portion 1b (2b) of the curtain 1 (or curtain material 2) during storage.
In the present invention, the "hem width Wc' during storage" is the curtain width of the lower portion (hem portion) 1c (2c) of the curtain 1 (or curtain cloth 2) during storage.
Examples 1-1 to 1-6, Examples 2-1 to 2-3, Examples 3-1 to 3-4, and Comparative Examples 1 to 3 are shown in Table 3 and Examples 4-1 to 4- Table 4 shows 3, Example 5-1 to 5-4, Example 6-1 to 6-7, and Specific Example 1.

Furthermore, among the evaluations in Tables 3 and 4, the evaluation of ease of storage is as follows: (1/2 of upper width Wb when extended)-upper width Wb' when stored is "-10.0 cm or less". When it was "x" (nothing actually became x), when it was "greater than -10.0 cm and 0.0 cm or less", it was considered "△" and "greater than 0.0 cm and 15.0 cm or less". When it was, it was marked with "○", and when it was "greater than 15.0 cm", it was marked with "⊚".
In the evaluation of the stored shape in Tables 3 and 4, when the absolute value of the stored upper width Wb-hem width Wc is “greater than 8.0 cm”, it is “Δ” and “greater than 5.0 cm, 8. When it was "0 cm or less", it was marked "○", and when it was "5.0 cm or less", it was marked "⊚".

In the comprehensive evaluation in Tables 3 and 4, the evaluation of the ease of storage and the evaluation of the shape at the time of storage are added to the evaluation of the shape at the time of extension in Tables 1 and 2, and the evaluation with the lowest evaluation among the three evaluations is comprehensive. It was evaluated.
For example, in the case of Comparative Example 1, the ease of storage and the evaluation of the shape when stored are good, but the evaluation of the shape when stretched, which is the most important as a curtain, is “x” (that is, even when trying to close a curtain of a different shape). Since it could not be closed and it was not possible to sufficiently block the light entering through the window, which is the original function of the curtain), the overall evaluation was rated as "x". The same applies to other examples, comparative examples, and specific examples.

<Evaluation of test 2 (evaluation of ease of storage)>
Considering the examples, comparative examples, and specific examples shown in Tables 3 and 4, the curtain having any bending resistance G and sewing fold ratio H2 is stored as the curtain 1 as the set width ratio H1 becomes smaller. It's getting easier.
Of these, Example 5-4 in which the set width ratio H1 which is the only “Δ” in the evaluation of easiness of storage is “0.95” is the upper width Wb′ during storage, but the upper width Wb during storage is Since the value is smaller than Wb, in fact, if the set width ratio H1 is "0.95 or less", the curtain is contracted (curved or contracted) in the curtain width direction H to open the curtain. It is understood that it is possible (even if the set width ratio H1 has an upper limit, it is possible to store the curtain if at least the set width ratio H1 is set to "0.95 or less").

Further, comparing this embodiment 5-4 with the embodiment 5-3 in which the set width ratio H1 is "0.70", in the embodiment 5-4, (1/2 of the upper width Wb at the time of extension)- The value of the upper width Wb' at the time of storage is a negative value of "-9.5 cm" (that is, the upper width Wb' at the time of storage is larger than 1/2 of the upper width Wb at the time of extension). However, in Example 5-3, the value of (1/2 of the upper width Wb at the time of extension)-the upper width Wb' at the time of storage is a positive value of "+11.5 cm" (that is, the upper width at the time of storage). The width Wb' is smaller than 1/2 of the upper width Wb at the time of extension).
Therefore, while the set width ratio H1 is changed from "0.95" to "0.70", the value of "(1/2 of the upper width Wb when extended)-the upper width Wb' when stored is negative. There is a value of the set width ratio H1 that switches from "0" to a positive value, and it can be said that this value is "0.825" which is an intermediate value between "0.95" and "0.70".

Further, as described above, regardless of the bending flexibility G and the sewn fold ratio H2, the smaller the set width ratio H1, the easier the curtain 1 can be stored. Similarly, in the case of G and the curtain having the sewn fold width ratio H1, the set width is "(the upper width Wb at the time of extension) 1/2-the upper width Wb' at the time of storage switches from a negative value to a positive value". The value of the ratio H1 exists, and it can be said that this is “0.825”.
Therefore, it can be said that “0.825 or less” is preferable as the upper limit of the set width ratio H1.

<Evaluation of Test 2 (Evaluation of shape when stored)>
Considering the values of the upper width Wb' and the hem width Wc' at the time of storage in all the examples, comparative examples, and specific examples shown in Tables 3 and 4, the set width ratio H1 and the seam fold width ratio H2 thereof, It can be said that the values are random regardless of the bending resistance G, but examples and comparative examples in which the bending resistance G is relatively large (the bending resistance G is 110.8 mm, 95.7 mm, 91.3 mm). In the evaluation of the shape at the time of storage, although at most “◯” was stopped and there was no “⊚”, the examples with comparatively small bending resistance G and comparative examples (having bending resistance G of 71.8 mm and 55. 5 mm, 33.8 mm) are almost "○" or more, and "◎" is also very large. Therefore, the lower the bending resistance G to a certain extent, the smaller the difference between the upper width Wb' and the hem width Wc' during storage. It is also thought that there is a tendency to become.
The evaluation of the stored shape is shown in the evaluation of the ease of storage described above (1/2 of the upper width Wb during extension)-the upper width Wb' during storage is a positive value (that is, , The upper width Wb' when stored is smaller than 1/2 of the upper width Wb when extended), even if the hem width is slightly wider than the upper width when stored, the light coming in from the window There is little obstruction, and it can be said that the original function of the curtain is not significantly affected.
Further, even in the above evaluation of ease of storage, if the curtain is fastened with tassels or the like during storage, the upper width Wb' during storage is naturally much smaller than half the upper width Wb during extension. Therefore, it can be said that the degree of importance is lower than the evaluation of the shape at the time of extension related to the original function of the curtain.

<Evaluation of Test 2 (Comprehensive evaluation)>
Considering the examples, comparative examples, and specific examples shown in Tables 3 and 4, folds 3 are formed on the curtain fabric 2 with an appropriate set width ratio H1 for any curtain having a bending resistance G (setting process). ) Then, if the sewn fold 3'is sewn at an appropriate sewn fold width ratio H2, three of "shape when stretched", "ease of storage", and "shape when stored" are evaluated as "○" or more at the same time. You can do it.
In detail, if the bending resistance G is 110.8 mm, all three evaluations are "O" or more by setting the set width ratio H1 and the seam fold width ratio H2 in Examples 1-2 and 1-3. (That is, the overall evaluation is "○").

Similarly, even if the bending resistance G is 95.7 mm, if the set width ratio H1 and the sewing fold width ratio H2 as in Example 2-1 are set, the overall evaluation becomes “◯”, and the bending resistance G is 91. If the set width ratio H1 and the seam fold width ratio H2 are the same as those in Example 3-4, the overall evaluation is “◯”, and even if the bending resistance G is 71.8 mm, Example 4 is also used. If the set width ratio H1 and the seam fold width ratio H2 are -1, the overall evaluation is "○", and even if the bending resistance G is 55.5 mm, it is as in Examples 5-1 to 5-3. If the set width ratio H1 and the sewn fold width ratio H2 are set, the comprehensive evaluation is “◯” or “⊚”, and even if the bending resistance G is 33.8 mm, all of the embodiments 6-1 to 6-6 are performed. If the set width ratio H1 and the sewn fold width ratio H2 are set, the overall evaluation is “◯” or “⊚”.
If the set width ratio H1 is “0.70 or less” as in Examples 1-2, 3-4, 4-3, 5-3, 6-5, and 6-7, it is easy to store. The evaluation of the shape at extension is "○" or more (that is, "easy to store" and "shape at extension" can both be achieved), and the above-described upper limit of the set width ratio H1 is Thus, it can be said that “0.70 or less” is more preferable.

From the results of Tests 1 and 2, as in the set processing machine 10 according to the present invention, by forming the folds 3 on the curtain material 2 with an appropriate set width ratio H1, the set processing suitable for the curtain 1 can be performed, and the curtain It is possible to suppress that the overall shape of 1 (mainly the overall shape when stretched in the curtain width direction H) becomes an irregular shape such as a hakama shape, an inverted trapezoidal shape, or a barrel shape (“suppression of curtain deformation”). ), while maintaining the original shape of the curtain, the entire shape of the curtain 1 does not have a hakama-like shape, so even when it is used for windows, etc., it is possible to sufficiently block the light to be injected, and the original function of the curtain is maintained. I can do it.
Further, from the results of the tests 1 and 2, even in the curtain 1 having the hard cloth portion and the soft cloth portion as in Examples 2-1 to 2-3, the bending resistance G calculated by the above-mentioned formula 1 was obtained. The average value of B is similar to that of other examples and specific examples having a uniform flex G, and the range of the above-mentioned flex G (not particularly limited, for example, JIS-L-1096:2010). If the flexibility is in accordance with Method A, the lower limit thereof may be, for example, 30 mm or more, preferably 40 mm or more, more preferably 50 mm or more, and the upper limit is not particularly limited. (For example, 120 mm or less, preferably 100 mm or less, more preferably 90 mm or less), or the set width ratio H1 and the sewing fold width ratio H2 of the curtain 1 having the above hard cloth portion and soft cloth portion are uniform. Similar to other examples and specific examples having the bending resistance G, the range of the set width ratio H1 described above (the lower limit value of the set width ratio H1 is 0.20 or more, preferably 0.23 or more, more preferably When it has an upper limit value of 0.30 or more, for example, 0.95 or less, preferably 0.825 or less, more preferably 0.70 or less) and the range of the sewing fold width ratio H2 (particularly Although not limited, for example, 1.0 or more and 3.0 or less, preferably 1.2 or more and 2.7 or less, and more preferably 1.4 or more and 2.4 or less) It can be seen that "suppression" can be realized.
