Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing pleated products such as skirts, dresses, blouses, slacks and the like that have been pleated.

[0002]

2. Description of the Related Art A process for making a crease in a cloth, such as a skirt, is known. For example, a skirt with a crease is called a flared skirt, a gathered skirt, a pleated skirt, and the like, and the process of adding this kind of fold to a skirt, a dress, a blouse, a slacks, etc. is generally called pleating. The "crease" itself is called a pleat in relation to pleating.

When pleated, a moderate amount of shading appears on clothes, and a visual effect provides an aesthetic impression. Further, since the pleating process adds flexibility to the garment, the cramped feeling can be wiped off and sufficient activity can be secured even when the garment has a small dimension.

Pleated products such as pleated skirts, dresses, blouses and slacks are usually formed by the following steps.

First, the cloth is cut into parts having a predetermined shape (cutting process).

A part is pressed (press working). By pressing, sharp pleats are formed by the following pleating process.

The parts are put on a pleating machine and desired folds (pleats) are attached to the parts (pleating). Complex pleats that are difficult to form with pleating machines are done manually.

Parts are placed in a heat treatment apparatus and heated by saturated steam for heat treatment (heat treatment processing). By this heat treatment, the pleats are fixed and the collapse of the pleats is prevented, and the pleats having good holding properties are obtained.

Sew parts with pleats with a sewing machine,
Finish pleated products (sewing).

As described above, the pleated product is subjected to pleating and then sewn into a pleat product. Here, after pleating the fabric, the pleated fabric may be cut into parts and then sewn. However, even in this case, sewing is still performed after the pleat processing.

The pocket attachment and the button attachment are performed in the sewing process.

Recently, parts are sewn into semi-finished products,
Post pleating for semi-finished products (po
A processing method which should also be called "st pleats process" is provided in Japanese Patent Laid-Open No. 2-269866.

According to this vowel pleat processing, since the pleat processing is performed after sewing, the flexibility characteristic of the pleat processing is not lost. In addition, since there are no restrictions on sewing, it is possible to design freely and obtain designs that are rich in variations with different aesthetic impressions.

[0014]

As described above, according to the conventional processing method, the cutting process and the press process are performed.
Pleating, heat treatment, sewing, and many other processes, as well as post-processing to put pleated products in the packaging box, it takes a lot of time to commercialize them, and it is not possible to quickly respond to demand.

Pleating is performed by sandwiching a part before sewing or a part after sewing between an upper mold and a lower mold (pleats) having an uneven shape corresponding to a desired fold (pleat). For widely used pleats, standard pleats made of metal are prepared in consideration of durability, and pleats are processed by attaching the standard pleats to a pleating machine.

However, pleats that are difficult to perform with a pleating machine, for example, complicated pleats such as taper side pleats, accordion pleats, and pattern matching are manually performed by using a paper pleated mold. From the point of view, it takes time to commercialize.

In both the pleating machine and the manual work, the pleating process utilizes the pleating type.
Pleating without pleats is not possible, and the design of pleats is restricted, making it difficult to produce pleat products with a wide variety of designs.

Even if a new pleat type is to be prepared, a pair of upper and lower pleat types must be prepared. In addition, a pleat mold is formed in a size such that the whole is pleat-processed at once. Therefore, it takes a long time to mold the pleated mold, and the pleated mold is a hindrance to rapid commercialization. Furthermore, the pleat type becomes expensive.

It is an object of the present invention to provide a method for processing a pleat product, which enables swift commercialization of pleat products having a wide variety of designs.

[0020]

In order to achieve this object, according to the present invention, a core plate is used in place of the conventional pleat type consisting of an upper die and a lower die, and a semi-finished product after sewing is used. The product is folded on the core plate as the core. Then, the folded semi-finished product is stored in a box to prevent the shape from collapse, and the semi-finished product is placed in the box and heat-treated in a heat treatment apparatus.

When the semi-finished product is heat-treated while being placed in a box and folded, the semi-finished product is provided with folds (pleats) along the edge of the core plate without losing its shape during the heat treatment.

[0022]

Embodiments of the present invention will now be described in detail with reference to the drawings.

A method of processing a pleated product according to the present invention for a T-shirt (tee shirt) 10 as shown in FIG. 1 will be described. Assuming that the parts are left and right sleeves 11L11R, front body 12F, and back body 12B in order to avoid complication, the sleeve, front body, and back body are first cut from the cloth, and the edges thereof are sewn with a sewing machine, and then, as shown in FIG. (A) Semi-finished product 14
To form.

Then, the semi-finished product 14 is folded. The folding of the semi-finished product 14 may be performed along the core plate 16 from the beginning, but in the embodiment, the semi-finished product is first folded to an appropriate size and then the core plate is used.

That is, as shown in FIG. 1 (A), the left and right sleeves 11L11R are folded to the front (upper in the drawing). Then, as shown in FIG. 1B, the left half is overlapped with the right half along the center line.

The core plate 16 is placed on the semi-finished product 14 previously folded into the shape shown in FIG.
As shown in (D), the left part and the right part are folded into a table, and the edge of the semi-finished product is processed as shown in (E) in FIG. Then, fold the upper part to the front as shown in.

The core plate 16 is formed by cutting a material having appropriate hardness and air permeability, such as cardboard, into a desired shape. Since the core plate 16 serves as a core for folding, it is usually formed in a rectangular shape such as a square or a rectangle, but may be formed in a pentagonal shape if it does not hinder folding.

Then, as shown in FIG. 3 (F), the semi-finished product 14 together with the core plate 16 is folded twice on the surface,
As shown in Fig. 3 (G), the edge of the semi-finished product is processed,
It is folded into the shape shown in FIG.

Semi-finished product 1 folded around the core plate 16
As shown in FIG. 4, 4 is stored in the box 22. Box 22
Is formed from, for example, cardboard with good air permeability, and in the embodiment, the box-shaped upper half (cover) and lower half are connected at one end so that the cover can be locked to the lower half. There is. The width and depth of the box 22 are set to accommodate the semi-finished product 14 loosely, while the height of the box is set to press the semi-finished product from above and below when the cover is covered.

The shape of the box 22 is an example, and it goes without saying that boxes of various other shapes can be used. Box 2 for wrapping paper
2, the semi-finished product 14 may be wrapped with wrapping paper, and the wrapping paper may be bound with a string. In addition, the semi-finished product
You may hold down. Furthermore, it is advisable to puncture the semi-finished product 14 with a needle, a pin or the like to prevent the folding of the semi-finished product from loosening.

Since the box 22 is formed as described above, the semi-finished product 14 is pressed from above and below and is stored in the box without loose folding. The box 22 is the heat treatment device 2
Put in 4.

The heat treatment apparatus 24 is a known one, and the inside of the heat treatment apparatus is filled with saturated steam.
The semi-finished product 14 in the box is fully immersed in the saturated steam up to the inside thereof because 2 is made of cardboard having good air permeability. Since the semi-finished product is folded around the core plate 16, the semi-finished product is dipped in the saturated steam to form folds (a kind of pleats) along the edge of the core plate into the semi-finished product and are fixed. If the inside of the heat treatment device 24 is made negative pressure, the pleats can be sharply formed.

Then, as shown in FIG. 5 in which the semi-finished product 14 after the heat treatment is taken out from the box 22 and spread out, the core plate 1
A pleated T-shirt (pleated product) 10 having the outer shape of 6 as a unit is obtained.

In the conventional processing method, a part before sewing or a part (semi-finished product) after sewing is sandwiched between an upper die and a lower die (pleat type) having irregularities corresponding to a desired pleat,
Heated after pleating.

On the other hand, as described above, in the present invention, the pleats having the outer shape of the core plate 16 as a unit are attached to the semi-finished product by heat-treating the semi-finished product while being put in the box 22 and folded. In the heat treatment, pleating is performed at the same time. Further, the folding of the semi-finished product 14 along the core plate 16 is performed manually, but is performed quickly along the core plate which is the core, and can be performed quickly. Therefore, as compared with the conventional processing method in which the pleating process and the heat treatment process are independently performed, the number of steps is reduced in the present invention, the pleated product can be rapidly produced, and the demand can be sufficiently satisfied.

Further, in the conventional processing method, since the pleat mold is large in one set in the upper and lower parts, the pleat mold cannot be molded quickly and inexpensively. However, in the present invention, the core plate 16 is used instead of the pleated type, and the core plate is a small one that can be formed by cutting cardboard or the like and can be folded and made into a compact semi-finished product 14. Good. Therefore, the core plate 16 can be formed quickly and inexpensively, and the formation of the core plate does not hinder the crystallization. Moreover, various and various core plates 16 can be easily molded.

In the conventional method, the manual pleating process cannot be performed quickly because the parts or semi-finished products are sandwiched between the upper and lower pleated molds one by one. Therefore, it takes a long time for the pleating process by hand, and the pleating process tends to become a bottleneck in the width of a series of steps.

However, according to the present invention, the semi-finished product 14 can be quickly folded along the core plate 16. Further, although the folds are fixed at the same time in the heat treatment step, the heat treatment time does not become long. Therefore, in the present invention, there is no step that becomes a neck, and the pleated product can be quickly obtained.

Since the creases are fixed (a kind of pleat processing) after sewing, it is possible to design without being restricted by sewing. Then, by changing the shape, size and position of the core plate 16 or by folding the right half and the left half together as in the embodiment, it is possible to create a design with a variety of unique aesthetic impressions and high added value. Pleated products are easily obtained.

Furthermore, since the parts are sewn before pleating, it is not necessary to consider the restoring force of the cloth, and it is not necessary to sew while holding the parts. Therefore, sewing can be performed quickly. In addition, since it is not pleated, the overlapping of the fabrics is small and the sewing can be easily performed with the sewing machine.

Since the pleats are processed after the sewing, the flexibility, which is a characteristic of the pleats, is not impaired by the sewing, and a pleat product having high flexibility can be obtained.

The sewing is carried out in advance, and the pleated product is immediately completed by pleating, and it is not necessary to add a hand after the pleating. It is also compactly folded. Therefore, it can be taken out from the box 22 and stored in the packaging box as it is. In particular, if a packaging box is used as the box 22, the packaging step can be omitted, the product can be taken out of the heat treatment device 24 and immediately flowed to the sales route, and the commercialization is further accelerated.

Since it is compactly folded and stored, it can be easily carried. Further, since it is wrapped in the core plate 16, it does not lose its shape while being carried.

The core plate 16 can be molded at low cost, and even if the pleated product is sold with the core plate attached, the pleated product does not become expensive even if the core plate is so-called disposable.

Even if the pleats are impaired by wearing and the flexibility of the pleated product is lost, the pleated product having high flexibility can be easily restored simply by folding the core plate 16 and performing heat treatment.

In the conventional processing method of pleating with a pleating machine, there is a risk that the pleated type attached to the pleating machine may break the button or the pleated type may be damaged by the button, so that the buttoning is performed after the pleating. .

On the other hand, in the present invention, the semi-finished product 14 is merely folded on the core plate 16 made of a material such as cardboard, and there is no risk of the button being broken by the core plate.
Further, even if the core plate 16 is somewhat damaged by the button, there is no problem because the core plate is disposable. Therefore, buttons can be attached before pleating, and pleated products with buttons are also
It can be handled like a pleated product without buttons. Further, the pocket does not become an obstacle to the pleating process, and the pocket can be sewn before the pleating process.

In the case of a semi-finished product with buttons, it is preferable to fold the buttons so that they are located on the uppermost surface, and sandwich the separator between them and the lower surface so that the marks of the buttons do not appear on the lower surface. . Further, if it is difficult to fold the button so that it is located on the uppermost surface, it is preferable to isolate the upper and lower sides of the button with a separating plate. For example, the separator is made of breathable cardboard, as is the core, box.

Another embodiment is shown in FIGS. Also in this embodiment, the T-shirt 60 is to be pleated. Similarly to the first embodiment, the left and right sleeves 61L. 61R,
Semi-finished product 64 by sewing front body 62F and back body 62R in advance
Then, as shown in FIG. 6 (A), the sleeves are folded on the front side, and then, as shown in (4), the lower half is overlapped with the upper half.

Then, as shown in FIG. 6 (B),
The lower part is overlapped with the upper part along the center line, and the left half part is overlapped with the right half part along the center line, and the semi-finished product 64 is folded compactly as shown in FIG. 6C.

In this embodiment, the folded semi-finished product 64
A bellows-shaped core plate 66 having substantially the same outer shape as that of the present invention, which can be bent into six, is used. As shown in FIG. 7D, the core plate is put into a semi-finished product, and the core plate is bent. Then, the semi-finished product is folded together with the core plate (see FIGS. 7D to 7F).
Instead of being put in the semi-finished product 64, the core plate 66 may be placed above or below the semi-finished product and bent.

The semi-finished product 64 is loosely housed in the box 72 which also serves as a packaging box, and the semi-finished product is pressed from above and below by the cover to put the box in the heat treatment device 74 (see FIG. 8). Then, after the heat treatment, the semi-finished product 64 is taken out from the box 72 and unfolded, and as shown in FIG. 9, a T-shirt (pleated product) 60 having pleats with the outer shape of the core plate 66 as a unit is obtained.

In this embodiment, since the bendable core plate 66 is used, the semi-finished product 64 is naturally folded by bending the core plate. Therefore, folding of the semi-finished product 64 can be performed accurately and quickly without requiring skill. Further, since the semi-finished product 64 is sandwiched and folded by the bent core plate 66, sharp pleats are formed. The bendable core plate 66 can also be formed at an extremely low cost as compared with the conventional pleat type.

Since the box 72 is a packaging box, it is sent to the sales route immediately after being taken out of the heat treatment apparatus without passing through the packaging process. Further, since it is sandwiched by the core plate 16 and folded, the pleats are held well and the shape of the pleats does not collapse.

The core plates 16, 66, the boxes 22, 72, and the separators need only have appropriate hardness and have good air permeability so as not to impede the flow of saturated steam in the heat treatment process. Not limited.

A shape that does not easily become a folding core, for example,
If you make a heart-shaped, star-shaped, or substantially rained animal or plant stand out on the core plate, or use a separately molded plate of this shape as an auxiliary core plate, put it on the core plate and fold the semi-finished product The shape of heart, etc. can be molded and fixed by heat treatment, and a pleat product completely different from conventional pleat products can be obtained.

In the embodiment, the present invention has been described by exemplifying the T-shirts 10 and 60 as the pleated products, but the present invention is not limited to the T-shirt, and the blouse, the skirt, the slacks,
Various pleat products such as one-pieces and cocktail dresses can be processed by the processing method of the present invention.

The folding in the embodiment is an example, and the folding can be set arbitrarily by changing the position of the core plate.

The above-mentioned embodiments are intended to explain the present invention, and do not limit the present invention at all, and all modifications and alterations made within the technical scope of the present invention are also included in the present invention. It goes without saying that it will be done.

[0060]

As described above, according to the method for processing a pleat product of the present invention, the outer shape of the core plate is set as a unit by heat-treating the semi-finished product in the box while folding the core plate as the core. Since the pleats are attached to the semi-finished product and the folds are fixed in the heat treatment to reduce the number of steps, the pleated product can be rapidly produced.

Since the core plate is used as a core, folding can be performed quickly, and even if the folds are fixed at the same time in the heat treatment step, the heat treatment time does not become long. Also, a core plate instead of the pleat type can be easily molded. Therefore, there is no step that becomes a neck, and the pleated product can be rapidly produced.

Since the pleats are processed after sewing, it is possible to design without being restricted by sewing. By changing the shape and size of the core plate and the position of the core plate, or by folding and folding the semi-finished products, a design with a variety of unique aesthetic impressions can be embodied in a pleated product, resulting in a pleated product with high added value. Easily obtained.

Since the parts are sewn before pleating, it is not necessary to consider the restoring force of the cloth, and it is not necessary to sew while holding the parts. Therefore, sewing can be performed quickly. Further, since it is not pleated, the number of cloths sewn at the same time is small and the sewing can be easily performed.

Since the pleats are processed after the sewing, the flexibility which is a characteristic of the pleats is not impaired by the sewing, and a pleat product having a high flexibility can be obtained.

Since the sewn is performed in advance, the pleated product can be immediately completed by performing the pleating process, and after the pleating process, the pleated product can be quickly commercialized without any need for any additional work.

Further, since it is compactly folded, it can be taken out of the box and stored as it is in the packaging box, and it can be easily carried without losing its shape. Although the core plate is disposable, it can be inexpensively molded, which does not make the pleated product expensive.

If a packaging box is used as the box, the packaging process can be omitted, and the product can be put on the sales route immediately after being taken out from the heat treatment apparatus, which further speeds the commercialization.

Even if the pleats are impaired in their retainability due to wearing and the flexibility of the pleated product is lost, the pleated product having high flexibility can be easily restored simply by folding it on the core plate and subjecting it to heat treatment.

There is no risk of the buttons being broken by the core plate, and buttons can be attached by sewing before pleating. You can also sew pockets by sewing before pleats.

If a bendable core plate is used, the semi-finished product is naturally folded due to the bending of the core plate, and the folding of the semi-finished product can be performed accurately and quickly without requiring skill. In addition, because the semi-finished product is sandwiched between the bent core plates and folded, sharp pleats can be formed. Also,
Good pleats retention and no loss of shape.
