DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edge stitching tape or label in which a fiber fusion portion on both side edges is wrapped with a sewing thread, and further relates to a margin stitching method for accurately and densely covering the fiber fusion portion on both side edges of a tape material. .

[0002]

2. Description of the Related Art A woven polyester label to be sewn on a commercially available textile is woven in a narrow loom into a belt shape, and is further woven.
Shred each sheet. The method of weaving with a narrow loom has the drawbacks of low production efficiency and high cost.Therefore, a method of weaving a wide fabric with synthetic fibers using a high-speed loom such as a rapier loom and heat-cutting the wide fabric into a strip shape. Has become the current mainstream.

[0003]

When a wide woven fabric is heat-cut into a strip, the weft yarn of the wide woven fabric is melt-cut, and linear fiber fusion parts are formed on both side edges of the obtained woven tape. This fiber fusion portion has a hard glass-like appearance when it is a polyester fiber, and has a remarkable sense of incongruity with the entire structure in feel and appearance. When the label cut from the woven tape is bent to be sewn to clothes, the fiber fusion portions on both side edges are broken to produce a fusion protrusion. When the label with the melted protrusion is sewn on clothes, the melted protrusion contacts the skin of the user if it is underwear, and it itches, causing discomfort when worn and possibly damaging the skin. In addition, in the case of an outer garment such as ski wear, the sweater or the inner garment shirt worn underneath may be frayed or fluffy.

[0004] A large number of users, such as apparel manufacturers, have strongly demanded prevention of generation of fiber fusion parts for woven labels obtained by heat-cutting wide woven fabrics. As a measure to prevent the occurrence of fiber fusion parts, a method of ultrasonically cutting wide fabrics has already been proposed.However, even if ultrasonic cutting can reduce the melted portion of the fiber, the cutting point is likely to be frayed. The problem remains. On the other hand, when both sides of the woven label are sewn with an overlock sewing machine and the fiber fusion part is wrapped with sewing thread, the protrusion due to the fiber fusion part on both sides is reduced, and the sense of incongruity with the entire structure regarding the feel and appearance can be considerably eliminated, In overlock sewing, due to the presence of a woolly thread to be used and a sewing thread tangled with the woolly thread,
The width of the stitches on both side edges is widened and the portion rises high, which is inconvenient when a woven label is sewn and is not aesthetically preferable.

[0005] An object of the present invention is to provide a woven tape having excellent aesthetic appearance and a good tactile sensation, in which the side seams at both side edges are not conspicuous.

It is another object of the present invention to provide a woven label which is excellent in aesthetic appearance and has a good tactile sensation at both side edges without being noticeable.

[0007] Another object of the present invention is to provide a woven label that does not generate any protruding pieces even when folded during sewing, and does not cause discomfort to a garment wearer.

Yet another object of the present invention is to provide an edge stitching method for automatically and quickly edge stitching a woven tape and tightly wrapping a fiber fusion portion on both edges with a sewing thread.

Still another object of the present invention is to provide an edge stitching method which does not pull the woven tape during the edge stitching and does not cause uneven sewing, thread breakage or fluffing of the sewing thread for single-ring stitching wrapping the fiber fusion portion. To provide.

[0010] These and other objects, features and advantages of the present invention will become more apparent to those skilled in the art from the following description.

[0011]

In order to achieve the above object, a woven tape according to the present invention is a woven tape obtained by heat-cutting a wide-width woven fabric. And a single loop stitch in which the sewing thread of the thread loop portion extends laterally along the vicinity of the tape side edge while crossing the tape side edge. In this woven tape, a single thread forming a single-ring stitch is closely in contact with each other while intersecting with the side edge of the tape, so that the fiber portion of each side edge is covered with the sewing thread.

In this woven tape, it is preferable that the inclination of the sewing thread of the single-ring stitch on both side edges is substantially symmetric with respect to the center line as viewed from the tape plane. When the woven tape is cut horizontally, a woven label can be obtained. If desired, this woven label partially weaves the shrinkable yarn as a weft yarn at the part to be folded at the time of sewing, and slightly dents both side edges of the part to be folded at the part to be folded due to shrinkage treatment after weaving. .

[0013] In the edge stitching method of the present invention, a tape material having a fiber fusion portion on both side edges is set up and fed in the longitudinal direction, and one of a sewing machine having a horizontally operated sewing needle and a forward and backward swinging looper is provided. A single loop stitch is formed in the lateral direction while feeding the sewing thread back and forth along the vicinity of the side edge of the tape. Further, in this edge stitching method, the tape material is reversed in the longitudinal direction, and in a reverse feed sewing machine having a horizontally operated sewing needle and a forward / backward swinging looper, a sewing thread is moved back and forth along the vicinity of the other tape side edge. To form a single-ring stitch that continues in the lateral direction while feeding.

In this edge stitching method, when the sewing machine needle passes below the front end of the presser foot, and the looper with the hooked hook is lowered to a position in front of the needle tip, the sewing thread of the thread hook is used. Is preferably in direct contact with the upper surface of the tip of the presser without directly contacting the side edge of the tape. As a result, the sewing thread of the thread loop portion does not directly contact the side edge of the tape at the time of tightening when a strong tensile force is generated, and always forms a constant single loop sewing regardless of the hardness and thickness of the tape.

[0015] Preferably, the tape material to be fed is positioned by a first guide plate that receives the upper edge and a second guide plate that is in contact with the lower edge. First
The second guide plate and the second guide plate can be repositioned in the vertical direction, and the vertical distance between the upper inner peripheral surface of the U-shaped portion of the first guide plate and the upper surface of the horizontal portion of the second guide plate corresponds to the width of the tape material. I do.

If necessary, when weaving the wide fabric, a contractile yarn is partially woven as a weft at a portion to be folded at the time of sewing. This wide woven fabric is heat-cut in a band shape, and then a single-ring stitch is formed along the vicinity of the side edge of the tape, and the obtained tape is partially shrunk by shrinking a shrinkable thread by a predetermined shrinking treatment, and folded at the time of sewing. Slightly depress both side edges of the site.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The woven tape of the present invention is a single woven tape which continues in the lateral direction while sending a sewing thread back and forth along the vicinity of both side edges where fiber fusion parts formed by heat-cutting a wide fabric are present. A chain stitch is provided, and one sewing thread forming a single ring stitch crosses the tape side edges and is in close contact with each other to cover the fiber fusion portion of each side edge. When the inclination of the single-ring stitch is substantially symmetric with respect to the center line when viewed from the plane of the tape, twisting of the tape or the label can be prevented. The edge-stitched tape may be used as a woven ribbon in the form of a strip, or may be cut laterally and used as a woven label. It is preferable to use the same thin thread as the weft thread of the tape material because the color tone of the entire tape can be unified. The tape can be flattened by a post-processing hot press, and the entire tape can be made approximately the same thickness.

In the case of a woven label, a contractible yarn partially woven as a weft may be provided at a portion to be folded at the time of sewing, and in this case, the folded portion is formed by shrinkage treatment after weaving. Slightly recess both sides of the site. This shrinkable yarn may be widely woven into the folded portion as a weft yarn, or 3 to 5 yarns may be woven only at each bending point. The shrinkable yarn may be a heat shrinkable yarn that shrinks by heating, or a water shrinkable yarn or a chemically reactive shrinkable yarn that shrinks by spraying or impregnating with water or a chemical.

In the edge stitching method of the present invention, a tape material having a fiber fusion portion is set up and sent in the longitudinal direction,
A single loop stitch is formed in the lateral direction while the sewing thread is fed back and forth along the vicinity of one tape side edge. In this method, after one side edge of the tape material is sewn in a single loop, the tape material may be inverted in the longitudinal direction, and a single ring stitch may be formed along the vicinity of the other tape side edge.

Preferably, when performing single-ring stitching on the tape side edge with a sewing needle, the sewing needle passes below the front end of the presser foot, and the sewing thread of the thread ring does not directly contact the tape side edge. Directly in contact with the upper surface of the tip of the presser foot. As a result, the sewing thread of the thread loop portion does not directly contact the side edge of the tape at the time of tightening when a strong tensile force is generated, and a constant single loop sewing can be always formed regardless of the hardness and thickness of the tape. The tape material to be fed is positioned by a first guide plate receiving the upper edge and a second guide plate in contact with the lower edge, and the first and second guide plates can be repositioned in the vertical direction.

[0021]

As is well known, a large number of tape materials 2 are simultaneously produced from the wide fabric 3 (FIG. 15), and a weaving mechanism 90 (FIG. 16) is used for weaving the wide fabric 3. The weaving mechanism 90 is constructed by combining a wide loom 92 such as a rapier loom, a projectile loom, an air jet loom, etc., which operates at high speed, and a jacquard machine 94 which performs a warp shedding motion when weaving a wide fabric. The organization is plain weave, oblique weave,
Any of satin weaves may be used. In the jacquard machine 94, the wide weaving machine 92 can weave a complicated pattern according to the pattern of the crest paper, and the weaving tape portion 2a weaves the wide fabric 3 having the characters 96 (FIG. 3) and the pattern arranged in a strip shape. To achieve. The obtained wide fabric 3 has a width of 70 to 260 cm and a wide loom 92.
For example, a cutting device installed in front of or behind the breast beam 96 is used to heat-cut the guide yarns 97 in a belt shape. This cutting apparatus comprises, for example, a large number of knives 98 arranged in parallel at regular intervals, each knife having a temperature of about 280 ° C., which is higher than the melting point of the polyester fiber.
Heat to Heat-cut many tape materials 2
Has a linear fiber fusion portion (not shown) on both side edges thereof, and each tape material is wound around a winding core 100 in a wide loom 92.

The core 100 of the obtained tape material 2 is shown in FIG.
The tape material 2 is pulled out from the winding core and transported by the first guide member 16 in the horizontal direction. The first guide member 16 feeds the tape material 2 standing in the longitudinal direction to the edge stitch sewing machine 14, and the U-shaped portion 58 of the first guide plate 60 and the second
Tape material 2 between horizontal portion 62 of guide plate 64
Is accurately positioned, and is intermittently fed in the direction of the arrow in FIG. In the tape material 2, in FIG. 11, the portion above the needle position 40b is the edge stitch width h.
The edge stitch width h can be adjusted by appropriately raising and lowering the tape position.

Referring to FIG. 11, when the sewing machine needle 40 advances and pierces the stopped tape material 2 at, for example, a point 102 a, the sewing thread 7 passed through the needle hole passes from the tape back side to the front side together with the sewing machine needle 40, Thread ring 1 on the tape front side
04 occurs. Immediately after the needle 40 advances to the position 40c in FIG. 9 and then starts retreating, the looper 42 descends to the position 42a behind the needle hole of the needle 40 on the tape front side, and further turns slightly to catch the thread ring portion 104. . Next, needle 40
Retreats from the tape material 2 and the tape material 2
It moves intermittently by the distance d in the direction of the arrow 1, ie, the direction of the arrow in FIG. The looper 42 ascends with the thread ring 104 caught up with the retraction of the sewing machine needle 40, further moves backward from the tape front side to the back side, and starts descending when it comes to the tape back side. When the sewing needle 40 is retracted to the position indicated by the solid line in FIG. 9, the looper 42 with the thread ring 104 hooked is lowered to the front position 42b at the needle tip. At this time, the sewing thread 7 of the thread ring portion 104 does not directly contact the side edge of the tape material 2 but directly contacts the upper surface of the tip of the presser foot 37. When the sewing machine needle 40 advances again, the looper 42 turns backward and separates from the thread loop 104, and the needle passes through the thread loop 104 pulled out by the looper 42 on the back side of the tape, and the point 1
The tape material 2 is pierced with 02b. As a result, the thread ring portion 104 of the sewing thread 7 can be sewn to the side edge of the tape. As the sewing machine needle 40 advances, the looper 42 starts to ascend, and the next thread loop 104 is sewn at the position 40b by the same operation as described above. The thread loop part 10 like
4 comes off the tip of the presser foot 37, and the sewing thread 7 of the thread ring 104 directly contacts the tape side edge. Since the sewing thread 7 of the thread ring portion 104 does not directly contact the tape side edge at the time of tightening where a strong tensile force is generated, the sewing thread 7 does not break or fluff regardless of the hardness and softness of the tape material 2 and the like. The formed single-ring stitch 8 can be formed. Hereinafter, the above operation is repeated to perform the sewn.

In the tape material 2 that has passed through the one-side sewing device 10, one sewing thread 7 forming the single-ring sewing 8 intersects with the fiber fusion portion on the side edge of the tape, and the seam is continuously formed without overlapping. Exists. Actually, the sewing thread 7 is closely contacted without forming a gap as shown in FIG. 11, and even a thin sewing thread covers the fiber fusion portion densely. When the one side edge of the tape material 2 of the one-side sewing device 10 is edge-stitched, a core 86 is formed.
(FIG. 12), and the wound tape material 2 is passed through the apparatus 10 again to obtain a woven tape 106 whose both side edges are sewn as shown in FIG. The woven tape 106
The inclination of the sewing thread 7 of the single loop stitch 8 at both side edges is substantially the same direction as viewed from the plane, and if the pattern is a repetitive pattern, the label may be cut into individual labels to form a woven label. This type of tape uses a thin sewing thread 7 and a thread
Since a, 102b, and the like are only one line in a straight line, the edge stitch width h can be easily adjusted by appropriately raising and lowering the tape position at the time of stitching. Is hardly impaired. The weft of the tape material 2 may be used as the sewing thread 7 for the woven tape 106, and the color and design of the entire tape can be unified.

The woven label 110 shown in FIG. 3 is made from a marginally sewn tape 112 (FIG. 2). In the label 110, the inclination of the sewing thread 116 of the single-ring stitches 114 and 115 at both side edges is substantially symmetric with respect to the center line as viewed from the label plane, whereby the twist of the label 110 can be effectively prevented. To obtain the tape 112, the tape material 2 is run once by the both-side sewing device 118 (FIG. 13).
At each side edge of the tape 112, single-ring stitches 114, 11
The single thread 116 forming the fiber 5 intersects with the fiber fusion portion on the side edge of the tape, and the seam is continuously present without being superposed. Even the thin sewing thread 116 covers the fiber fusion portion densely. The tape 112 may be used as it is if it is a series of patterns. The tape 112 is heat-cut laterally for each label at the position indicated by the dashed line in FIG.
The woven label 110 shown in FIG. 3 is obtained. The label 110 is end-held at a position indicated by a chain line in FIG. 3 in a subsequent bending step.

The double-side stitching device 11 for producing the tape 112
8 is a structure obtained by combining two apparatuses 10 of FIG. 7, but the first sewing machine 120 feeds the tape material 2 in the direction of the arrow in FIG.
The tape feed direction is opposite to that shown in FIG. Also, the second
In the sewing machine 122, the tape feed direction is the same as that of the sewing machine 14 (FIG. 7) because the tape material 2 is fed in the arrow direction of FIG. With respect to the first sewing machine 120, the tape material 2 coming out of the mounting table 124 of the tape winding core is
The guide member 130 is sent to the sewing machine 120 via the guide member 130 and the guide member 130 (FIG. 8). The tape material 2 having passed through the sewing machine 120 passes through a horizontal guide member 136 and a pair of upper and lower rollers 138 via vertical rollers 132 and 134, and the guide member 136 and the roller 138 are connected to the horizontal guide member 22 and the roller 24 (FIG. 7). It has almost the same structure. The second sewing machine 122 has the same structure as that of the sewing machine 14 (FIG. 7).

As shown in FIG. 14, below the roller 138 on the sewing machine 120 side,

4, and further through a horizontal roller 145 and a horizontal guide member 146 at the upper side, and then the vertical roller 1 on the sewing machine 122 side.
48,150. Due to the raising and lowering movement of the roller 144, a shift in the feed speed between the sewing machines 120 and 122 can be reduced. On the other hand, on the sewing machine 122 side,
An opening 156 is provided in the table 154 in the vicinity of the lower side of the table 2, and the tape material 2 picked up by the pair of rollers 152 is sent out to the lower side of the table. No) and wind it up on the core.

In the both-side sewing device 118, the core 158 of the tape material 2 is placed on the circular seat of the mounting table 124, the tape material 2 is pulled out from the core, and is conveyed in the horizontal direction by the guide member 130. The guide member 130 feeds the tape material 2 standing in the longitudinal direction to the sewing machine 120 to accurately position the tape material, and intermittently feeds the tape material to the left by the presser disk 160 while one of the single-ring stitches 115 (FIG. 2)
Is formed. The tape material 2 having one edge sewn is drawn in the horizontal direction via the guide member 136 and the rollers 138, 138, and is further fed out in the horizontal direction by the rollers 144, 145 and the guide member 146. The tape material 2 stands on the vertical roller 148 in the longitudinal direction, and at this time, the single-ring stitch 115 is located on the lower side. Further, the guide member 162
As a result, the tape material 2 is fed into the sewing machine 122, and the other single-ring stitch 114 (FIG. 2) is formed while being intermittently fed rightward by the presser disk 164. The tape 112 whose both side edges are sewn is taken up by rollers 152 and 152 and wound around a core below the table 154.

In still another woven label 166 shown in FIG. 6, both side edges 168 of the folded portion 167 are slightly concave. A shrinkable yarn 172 is partially woven as a weft in the tape material 170 that is cut into the woven label 166. Even if the shrinkable yarn is widely woven into a portion 174 that is a folded point 167 as shown in FIG. 3 to 5 strands may be woven only at each point. The shrinkable yarn 172 used is
For example, white polyester high shrinkage yarn (manufactured by Toray Co., Ltd.) or nylon yarn which heat shrinks at about 140 ° C. or rayon yarn which shrinks in water. The woven label 166 is partially shrunk by a predetermined shrinking process.

It is preferably 0.4 mm.

From the tape material 170 to the label material 175
To manufacture (FIG. 5), when weaving a wide fabric 176 (FIG. 17) in which both warp and weft are synthetic fiber yarns,
A shrinkable yarn 172 is partially woven as a weft at a portion to be folded at the time of sewing as a weft at a label interval, and then the wide fabric 176 is heat-cut in a strip shape for each tape portion 170a. The obtained tape material 170 (FIG. 4) is fed to a double-sided sewing device 118, and the both side edges are sewn by the device to form single-ring stitches 177,177. Next, when the tape material 170 having both edges sewn is heated to about 140 ° C. and pressed, as shown in FIG. 5, both side edges of the bent portion 167 are depressed by about 0.3 mm, for example. If desired, the label material 175 is processed with a resin such as a chemical glue to adjust the shape. The label material 175 is heat-cut laterally for each label by a separate heat-cut device (not shown) after resin processing, and each cut position is a mark 178. The obtained woven label 166 is pressed after being end-held in a subsequent bending step.

The woven label 166 has a folded point 167
The fiber fusion portion is bent downward due to the depressed both side edges, and no protruding piece of the fiber fusion portion is formed at the corners 182 of the both side edges in the bending line 180 as shown in FIG. Also,
Since the width of the folded portion 167 is slightly reduced, the portion is not exposed from the edge of the label body when the portion is bent to the back side, which is preferable from the viewpoint of aesthetics.

[0041]

According to the woven tape of the present invention, compared to a woven tape obtained by simply heat-cutting a wide woven fabric in a strip shape, the sewn portions on both side edges are inconspicuous and excellent in aesthetic appearance and have a good tactile sensation. . The woven label obtained from the woven tape does not produce any protruding pieces even when folded at the time of sewing, and does not cause discomfort to the wearer of the garment. When the woven label is sewn on an undergarment, a good feeling of wearing the underwear is maintained, and when sewn on an outer garment such as ski wear, the sweater or the inner garment worn under the garment does not cause any obstacle.

According to the edge stitching method of the present invention, it is possible to obtain a beautiful woven tape having a good tactile sensation of the woven tape and a narrow edge stitch width by tightly wrapping the fiber fusion portions of both edges with sewing threads. In addition, it is more preferable to perform edging with the same thread as the weft of the tape in terms of aesthetics of the woven tape. In this edge stitching method, the woven tape is not pulled at the time of edge stitching, and non-uniform sewing, thread breakage and fluffing of a sewing thread do not occur in single-ring stitching, so that the woven tape can be edged automatically and quickly. it can.
