Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a counterfeit product which is very similar to a genuine product by irradiating with light of a specific wavelength a woven tape or a woven label in which the inserting yarn and the fiber fusion portion located on both side edges are wrapped with a sewing thread. The present invention relates to an anti-counterfeit tape, a label and a method for manufacturing the same, which can easily detect

[0002]

2. Description of the Related Art In recent years, as the added value of famous brands and popular characters attached to labels and products themselves has increased,
There are also unscrupulous traders who try to get unfair profits from freeride, and counterfeit products with labels imitating brands and characters are flooding the market. Even in international transactions, counterfeit products are manufactured in large quantities using cheap labor in underdeveloped countries, and imported and sold at a far cheaper price than genuine products.
There are many incidents that cause significant damage to genuine product sellers.

[0003] These counterfeit products are very similar in appearance to genuine products due to the sophistication of dyeing technology and sewing technology for general textile products.
Even professional traders often cannot easily distinguish counterfeit products from genuine products. In this case, the counterfeit product exists for a long period of time in the same sales route as the genuine product, causing irreparable damage to the distributor of the genuine product.

For this reason, it is necessary to detect unfair counterfeit products at an early stage, such as clothing and ornaments. For example, clothing is made of special fabric or sewn with a special thread. This method is costly and cannot be easily changed even if it is re-mimicked by a manufacturer of counterfeit goods. Further, as a forgery prevention label, a part of the woven label is printed with ink containing a special fluorescent dye. In this printing method, the label surface design and name can be visually observed as usual, and the woven label emits light of a specific wavelength so that a retailer or the like can easily confirm the genuine product.
The label manufacturing process is increased and the raw material cost is increased.

[0005]

Regarding the anti-counterfeit label, a method of sewing a thread that reversibly changes color when irradiated with light of a specific wavelength is disclosed in JP-A-6-306727 and JP-A-7-92911. There is. Since the manufacturing process of these anti-counterfeit labels is the same as the conventional process, it can be manufactured at a relatively low cost. On the other hand, to make these anti-counterfeit labels cheaper,
A general method is to obtain a woven tape by weaving a wide fabric with a polyester fiber or the like using a high-speed loom such as a rapier loom and heat cutting the wide fabric into a band.

At the time of this heat cutting, the weft threads of the wide fabric are melt-cut, and linear fiber melted portions are formed on both side edges of the obtained woven tape. This fiber fusion portion is made of polyester fiber and has a hard glass-like appearance, and is very uncomfortable in touch and appearance with the whole structure. As a measure for preventing the generation of the fiber fusion portion, a method of ultrasonically cutting the wide fabric has already been proposed. However, even if the molten portion of the fiber can be reduced by the ultrasonic cutting, the cut portion is easily broken.

Further, JP-A-11-172546 and JP-A-11-200173 propose a method of wrapping a fiber fusion portion on both side edges of the tape with a single ring stitch portion. According to this manufacturing method, the woven tape is tightly edged by one sewing thread, and the tape is accurately fed to the single chain stitch sewing machine at the time of the edging. In this manufacturing method, in the process of manufacturing the woven tape or the woven label, only the step of sewing the side edges of the tape is added before the label cutting / bending process, and the high-speed manufacturing thereof is not hindered at all. In the obtained woven label and woven tape, the fused portions of the fibers on both side edges are tightly covered with the sewing thread and are not exposed, and no fused protrusions are generated even when folded, so that the skin is not damaged when sewn on underwear. ,
Even if it is sewn on the outerwear such as ski wear, the sweater or inner shirt worn underneath does not fray or fluff.

[0008] Even if it is possible to sew a woven label or woven tape in which the fiber fusion portion is wrapped with a single ring sewing portion, a thread that is reversibly discolored by irradiation with light of a specific wavelength for prevention of forgery, The addition of the two steps of weaving the photo-reversible color-changing thread and forming the single chain stitch portion leads to a considerable cost increase. In addition, this woven label and woven tape have some unevenness and roughness remaining on the side edges of the tape after the fiber fusion part is wrapped in the single-loop stitch part, and the tactile sensation is slightly deteriorated. If the brightness is significantly different from that of the tape weft, the presence of the back weft can be discerned from among the closely arranged sewing threads at the side edges thereof, which may cause a loss of aesthetic appearance of the label or tape.

An object of the present invention is to provide an inexpensive anti-counterfeit tape which has a good tactile sensation by eliminating unevenness and roughness on both side edges and is aesthetically pleasing. Another object of the present invention is to provide an inexpensive anti-counterfeit label which has good tactile sensation by eliminating unevenness and roughness on both side edges and is aesthetically pleasing.

Another object of the present invention is to provide a method of manufacturing an anti-counterfeit tape in which, when the woven tape is sewn, the fiber fusion portions on both side edges are tightly wrapped with the sewing thread and at the same time the insertion thread is fed. . Still another object of the present invention is to provide a forged tape in which the side edges of the tape are sewn using a well-known overlock sewing machine and the fiber-melted portions on both side edges are tightly wrapped with a sewing thread and at the same time an insertion thread is fed. It is to provide a manufacturing method. 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, an anti-counterfeit tape according to the present invention is a woven tape obtained by heat cutting a wide fabric, and fibers formed on both side edges by this heat cutting. Inserts where reversible color change occurs when at least one of the fusion zone and the single ring stitching part where the sewing thread of the thread ring part along the side of the tape side edge continues laterally while crossing the tape side edge. With a thread.
With this anti-counterfeit tape, the inserted yarn is in contact with the fiber melting part and is linearly enclosed in the single-loop stitch part, and by irradiating light of a specific wavelength, the inserted yarn is read to determine whether it is a genuine product. In addition to the determination, the influence of the fiber fusion portion is mitigated by the insertion thread while covering the fiber fusion portion of the side edge with the sewing thread forming the single chain stitch portion.

In the anti-counterfeit tape of the present invention, at least one of the sewing threads of the single loop sewing portion may reversibly change color by irradiation with light having a specific wavelength, instead of the insertion thread. The anti-counterfeit tape can be formed with an overlock sewing machine or the like to form a hem stitch portion along the vicinity of the side edge of the tape, and a linear insertion yarn can be enclosed in the hem stitch portion in contact with the fiber fusion portion.
The anti-counterfeit label of the present invention has a tape in which patterns and characters are continuously woven, and the tape may be cut into each pattern and characters. This label is sewn to clothing or the like after the folding step and the like.

In the manufacturing method of the present invention, a tape material having fiber-melting portions on both side edges is erected in the longitudinal direction and is fed at the same time, and at the same time, an inserted yarn that reversibly discolors when irradiated with light of a specific wavelength is used. Send it in contact with. By a sewing machine equipped with a horizontally operating sewing machine needle and a looper that swings back and forth, the sewing thread is wrapped back and forth along the vicinity of one side edge of the tape while being wrapped in a single continuous stitch portion that extends in the lateral direction. Enclose the insertion thread in a straight line.

In the manufacturing method of the present invention, a tape material having one side sewn is reversed in the longitudinal direction, and another insertion yarn is fed so as to be in contact with the other fiber fusion portion, and along the vicinity of the side edge of the other tape. It is preferable to wrap it up with a single chain stitch portion that continues in the lateral direction while feeding the sewing thread back and forth. At least one of the insertion thread or the sewing thread of the single loop sewing portion arranged on both side edges reversibly changes color when irradiated with light of a specific wavelength.

In another manufacturing method of the present invention, a tape material having a fiber fusion portion on both side edges is fed horizontally in the longitudinal direction, and at the same time, an inserted yarn that reversibly changes color upon irradiation with light of a specific wavelength is formed into a fiber. It is sent so that it contacts the melting part. With a known overlock sewing machine, the sewing thread is wrapped forward and backward along the vicinity of the side edges of each tape, and wrapped in a laterally continuing edge sewing section, and the insertion thread is linearly enclosed by the edge sewing section. Although the edge seams are formed on both side edges of the woven tape, the insert threads that reversibly change color upon irradiation with light of a specific wavelength may be arranged on only one side edge.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The anti-counterfeit tape of the present invention comprises a fiber fusion portion 4 formed by heat cutting a wide fabric.
(FIG. 2) Around the side edges where the (FIG. 2) exists, as shown in FIG. 1 to FIG. 1
As shown in 3, an overlock sewing machine etc.
Form 60. At the same time as forming the edging portions 6 and 160, the linear insertion yarn 7 is enclosed in the edging portion so as to be in contact with the fiber fusion portion 4.

The insertion threads 7 and 7 used in the present invention are usually
At least one of them is reversibly discolored by irradiation with light having a specific wavelength. The insertion thread 7 is usually one or many twisted threads like the sewing thread 5, but non-twisted threads or the like can also be used. The photo-reversible color-changing yarn emits light when irradiated with a lamp having ultraviolet rays such as black light, has almost no afterglow, and does not emit light when irradiated with ordinary sunlight or fluorescent light.

This photoreversible color-changing yarn is generally produced by kneading a predetermined amount of a fine inorganic fluorescent substance and spinning it, and usually, it is preferable to use a plurality of twisted yarns. The polymer in which the fluorescent substance is kneaded is polyester, nylon, acrylic, or cellulose acetate having a relatively high transparency, and polyester is preferably used as the polymer in terms of strength. If the knitting yarn of the fluorescent substance cannot be used alone for strength, it may be twisted with other ordinary fibers or made into a composite yarn wound around other fibers, for example, by kneading the fluorescent substance. It may be one or a plurality of filaments that are composite-spun, or a core-sheath composite thread or a composite thread in which a polymer in which a fluorescent substance is kneaded and an ordinary transparent polymer are laminated.

The fluorescent substance kneaded into the photo-reversible color-changing yarn preferably has a finer particle size, and generally has a particle size of about 1 to 1.
It is 3 μm. This fluorescent substance is, for example, a red color developing material (composition: Y ₂ O ₂ S: Eu), and this red color developing material has a peak wavelength of 624 nm. As a red color developing body,
Y ₂ O ₃ : Eu (peak wavelength 611 nm), YVO: E
u (peak wavelength 619 nm), (Y, Gd) BO ₃ : E
For example, u (peak wavelength 611 nm) may be used, and a plurality of these may be mixed and kneaded.

The fluorescent substance is a blue color former (composition: Sr ₅
(PO ₄ ) ₃ Cl: Eu) may be used, and this blue color developing material has a peak wavelength of 445 nm. As a blue color developing material, Z

Ag, Cu (peak wavelength 527 nm), (Zn, Cd)
S: Cu (peak wavelength 525 nm) and the like can be exemplified, and a plurality of these may be mixed and kneaded.

The photoreversible color-changing yarn used in the present invention may be produced by adding a photochromic compound which is an organic compound to a polymer and spinning the polymer. Photochromic compounds cause discoloration due to photoisomerization by moving hydrogen atoms, generation of free radicals by dissociation, ring cleavage, etc., and various azo compounds such as hydrazone, osazone, fulgide, stilbene, biimidazolyl and derivatives, bianthrone. Can be exemplified. As these compounds, those that change from colorless or pale yellow to blue, purple, magenta, or the like and whose color change is remarkable may be adopted.

The photo-reversible color-changing thread is generally colorless or light yellow, and although not shown, it is also possible to use it for at least one of the sewing threads 5 of the single ring sewing portion 6. In this case, the insertion yarn 7 may be a normal yarn instead of the photo-reversible color-changing yarn. Since the color of the photo-reversible color-changing yarn is usually about colorless, light yellow, light blue, light green or light pink, if the ground color of the woven tape 1 or the woven label 9 is dark, a feeling of strangeness is likely to occur, Its use is limited in terms of aesthetics.

In the woven tape 1 illustrated in FIG. 1, while the suture thread 5 is fed to the front and the rear of the tape along the vicinity of both side edges where the fiber fusion portion 4 (FIG. 2) formed by heat cutting of the wide fabric is present. A single chain stitch portion 6 that continues in the lateral direction is provided, and one sewing thread 5 that forms the single chain stitch portion 6 intersects the tape side edge 3 and covers the fiber fusion portion 4. At the same time as forming the single loop stitch portion 6, at least one of the single loop stitch portions 6, 6 usually has a linear insertion thread 7 (FIG. 2) that reversibly changes color upon irradiation with light of a specific wavelength. The melting portion 4 is contacted and sealed.

The edge-sewn tape material 2 (FIG. 1) may be used as the woven tape 1 in a strip shape or may be cut in the lateral direction to be used as the woven label 9. Tape material 2
Does not require any special process or device for manufacturing, since it only encloses the photo-reversible color-changing yarn as the insertion yarn 7 during its weaving. In addition, since the sewing thread 5 of the single chain stitch portion 6 is in close contact with the sewing thread 5, the color of the inner insertion thread 7 is not conspicuous,
The color tone of the entire tape can be unified by the color of the sewing thread 5. Therefore, even if the ground color of the tape is a dark color, it is possible to use a photo-reversible color-changing yarn that is nearly colorless in the insertion yarn 7. The woven tape 1 or the woven label 9 can be flattened by hot pressing as a post-treatment so that the entire tape has almost the same thickness.

The woven tape 1 or the woven label 9 is exactly the same as a normal one under the sunlight or fluorescent light even if the insertion yarn 7 is a photo-reversible color-changing yarn. Traders and consumers
When the woven tape 1 or the woven label 9 is irradiated with ultraviolet rays with a black light, it can be confirmed that the insertion thread 7 is colored between the sewing threads 5 of the single ring sewing portion 6, and it is easy to confirm that the woven tape is a genuine product. And it can be identified reliably.

In the woven tape 1 or the woven label 9,
Since the photo-reversible color-changing yarn is usually the same as the surrounding yarn, it is almost impossible to recognize that the photo-reversible color-changing yarn is enclosed as the insertion yarn 7. Even if we can recognize the existence of photo-reversible color-changing yarn,
It is practically difficult to enclose a photo-reversible color-changing thread that develops a specific color such as red in the single ring stitch portion 6. In the photo-reversible color-changing yarn, the inorganic fluorescent substance is generally less toxic than the organic compound fluorescent substance, and has good weather resistance, printability and other processability.

Instead of the photo-reversible color-changing yarn, a so-called photo-reactive yarn can be used as the inserting yarn 7 or the sewing thread 5 of the single ring sewing portion 6. This photoreactive yarn is manufactured by spinning with a polymer containing an infrared laser dye or by adhering an ink containing the infrared laser dye. This photoreactive yarn has a property of absorbing, for example, only infrared rays having a wavelength of 785 nm and emitting infrared rays having a longer wavelength, particularly infrared rays having a wavelength of 833 nm.

This photoreactive yarn is colorless and transparent, and even if infrared rays contained in the sunlight are absorbed and infrared rays of a specific wavelength are reflected under the sunlight, it cannot be visually identified. Since the infrared laser dye particularly absorbs infrared light having a wavelength of 785 nm and emits infrared light having a longer wavelength than this, in order to identify the photoreactive yarn, laser light having a wavelength of 785 nm is irradiated to obtain its reflected light. If a laser diode having a relatively narrow emission wavelength range is used as the light emission source, laser light having a wavelength of 785 nm can be emitted.

The weak infrared rays reflected from the photoreactive yarn can be amplified by an optical amplifier and then captured by a CCD camera to obtain an image of the photoreactive yarn. Since most of the reflected light has a wavelength of 833 nm, it is preferable to amplify the reflected light after passing through a notch filter having a wavelength range of 820 to 840 nm, and optical noise is removed by passing the filter to obtain a clear image. By identifying this image, it is possible to easily confirm that the garment with the woven label is authentic. Infrared light, which is reflected light, can be detected by an inexpensive CCD camera, and an expensive device such as an infrared scope is unnecessary.

On the other hand, as shown in FIG. 13, with respect to the woven tape 162 in which the fiber-melted portion formed by heat cutting of the wide fabric is present, the edge stitching portion 160 is formed along the both side edges with an overlock sewing machine or the like. May be formed. When forming the hemming portion 160, a linear insertion thread 164 is enclosed therein so as to be in contact with the fiber melting portion, and the supply mechanism of the insertion thread 164 is functionally different from that disclosed in FIGS. 7 and 11. It is almost the same. The overlock sewing machine performs overedging with one or two needles, and the formed edge seam has a large amount of thread polymerization and is thicker than the single chain stitch portion 6 in the following examples, but the sewing thread is If it is thin, it can be put to practical use.

In the manufacturing method of the present invention, the tape material 2 having the fiber-melting portion 4 is vertically erected and fed, and the sewing thread 5 is fed back and forth along the vicinity of one tape side edge 3 in the lateral direction. At the same time that the subsequent single chain stitch portion 6 is formed, the insertion thread 7 is enclosed in the single chain stitch portion. In this method, after forming the single chain stitch portion 6 and enclosing the insertion thread 7 on one side edge 3 of the tape material 2, the tape material is inverted in the longitudinal direction, and the other side area 3 of the tape side edge 3 is also reversed. The single loop stitch portion 6 may be formed along the line.

In another manufacturing method of the present invention, the tape material 166 is fed horizontally in the longitudinal direction, and at the same time, the insertion yarn 164 is fed so as to be in contact with the fiber fusion portion. An overlock sewing machine 170 (FIG. 14) such as a system overlock sewing machine is used to feed the sewing thread back and forth along the vicinity of one side edge of the tape, and the edge stitching portion 1 continues in the lateral direction.
It is wrapped with 60, and the insertion thread 164 is linearly enclosed by the edge sewing portion. With respect to the overlock sewing machine 170, as shown in FIG. 14, by arranging the rightward and leftward sewing machines continuously, it is possible to form the edge sewing portions 160, 160 on both side edges of the tape material 166 by one run. Even with one overlock sewing machine, if the tape material 166 is run twice, the edge sewing portions 160, 160 can be formed on both side edges thereof.

EXAMPLES The present invention will now be described based on examples, but the present invention is not limited to the examples and can be modified by those skilled in the art without departing from the spirit and scope of the present invention. It should be understood that there is.

In the woven tape 1 shown in FIG. 1 and FIG. 2, as is well known, the tape material 2 is produced by heat-cutting a wide woven fabric into a strip shape to produce a large number of the woven tapes at the same time. Part 4 (FIG. 2) has occurred. This wide fabric is woven with, for example, polyester fiber yarn, nylon fiber yarn, cotton yarn, and the like, and the synthetic fabric yarn is woven into at least the heat cut portion of the wide fabric.

In the present invention, the tape material 2 is provided with a single ring stitch portion 6 which continues in the lateral direction while feeding the sewing thread 5 (FIG. 1) back and forth along the vicinity of the side edge 3. In the single ring stitched portion 6, a linear insertion thread 7 is sealed in contact with the fiber fusion portion 4. The sewing thread 5 may be as thin as the weft thread of the tape material 2 or as thick as the wooly thread.
In general, the sewing thread 5 is a large number of twisted threads or non-twisted threads, and its design may be changed by changing its count and color.

Although the insertion yarn 7 is composed of a large number of twisted yarns, non-twisted yarns can also be used. The insertion yarn 7 is manufactured by kneading a predetermined amount of an inorganic fluorescent substance having a particle diameter of about 1 to 3 μm and spinning the mixture, and for example, a red color material (composition: Y ₂ O ₂ S: Eu) is used as the fluorescent substance. . The insertion thread 7 emits red light when irradiated with black light, has almost no afterglow, and is colorless when irradiated with ordinary sunlight or fluorescent light.

When the tape material 2 is continuously woven with characters 8 and patterns as shown in FIG. 3, the tape material 2 can be cut in the lateral direction and used individually as a woven label 9 or can be used as a woven tape as it is after edging. It is also possible to do so. The characters 8 and the patterns on the tape material 2 may be woven at the same time when the wide cloth is woven, or may be partially or wholly formed by printing after heat cutting into a large number of tape materials 2.

This cutting device is composed of, for example, a large number of knives arranged in parallel at regular intervals. A large number of heat-cut tape materials 2 have linear fiber fusion parts 4 (FIG. 2) on both side edges thereof, and each tape material is wound around an appropriate winding core in a wide loom.

The obtained winding core 90 of the tape material 2 is placed on the circular seat of the mounting table 20 in the one-side sewing machine 10 of FIG. 4, the tape material 2 is pulled out from the winding core, and is horizontally moved by the first guide member 16. Transport in the 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 62 of the first guide plate 60 and the second guide member 60.
Tape material 2 between the horizontal portion 63 of the guide plate 64
Is accurately positioned, and is intermittently fed in the direction of the arrow in FIG. 4 by the protruding table 34 and the pressing disk 36. In the tape material 2, the portion above the needle position 40b in FIG. 8 is the hemming width h, and the hemming width h can be adjusted by appropriately moving the tape position up and down.

Referring to FIG. 8, when the sewing machine needle 40 advances and pierces the stopped tape material 2 at, for example, a point 92 a, the sewing thread 5 passing through the needle hole passes together with the sewing machine needle 40 from the back side of the tape to the front side. Thread ring 93a on the tape front side
Occurs. Immediately after the needle 40 advances to the position 40c in FIG. 6 and then starts to retreat, the looper 42 descends to the position 42a behind the needle hole of the needle 40 on the tape front side, and further swivels slightly to hook the thread ring portion 93a. . Next, the needle 40 retracts and comes out of the tape material 2, and the tape material 2 intermittently moves in the arrow direction of FIG. 8, that is, the arrow direction of FIG. The looper 42 ascends while the thread ring portion 93a is hooked as the sewing machine needle 40 retreats, further moves backward from the tape front side to the back side, and starts descending when coming to the tape back side. When the sewing machine needle 40 retreats to the position indicated by the solid line in FIG. 6,
The looper 42 with the thread loop portion 93a still hooked descends to the front position 42b of the needle tip. At this time, the thread ring portion 93a
Sewing thread 5 of the tape side edge 3 without directly contacting,
It directly contacts the upper surface of the tip of the presser foot 37. Sewing needle 4
When 0 moves forward again, the looper 42 turns reversely and the loop 9
3a, the needle passes through the thread loop portion 93a pulled out by the looper 42 on the back side of the tape and pierces the tape material 2 at a point 92b. As a result, the thread ring portion 93a can be sewn to the tape side edge 3. The looper 42 starts to rise as the sewing machine needle 40 advances, and the next thread ring portion 93b is sewn at the position 40b by the same operation as described above.
As shown in the figure, the front thread ring portion 93a is disengaged from the tip of the presser foot 37, and the sewing thread 5 of the thread ring portion 93a directly contacts the tape side edge 3. Since the sewing thread 5 of the thread ring portion 93a does not directly contact the tape side edge 3 at the time of tightening in which a strong tensile force is generated, regardless of the hardness and softness of the tape material 2,
The single thread sewing portion 6 can be always formed with almost no breakage or fluffing of the sewing thread 5. Hereinafter, the above-described operation is repeated to perform edge sewing.

On the other hand, the insertion yarn 7 is fed from a yarn winding (not shown) located above the device 10 and supplied through a yarn tensioner 57 (FIG. 4) and a yarn guide 58. The insertion thread 7 further passes through the through hole of the thread guide bar 59 (FIG. 8) and runs substantially parallel to the tape side edge 3, and is wrapped in the single loop stitch portion 6 by the turning of the thread ring portion 93. Presser foot 3
When it passes through 7, it comes into contact with the side edge 3, that is, the fiber fusion portion 4.
As shown in FIG. 2, since the insertion thread 7 is interposed between the sewing thread 5 of the single chain stitched portion 6 and the fiber fusion portion 4, the fiber fusion portion 4
The thread breakage and the fluffing of the sewing thread 5 due to are almost completely prevented.

In the one-side sewing device 10, when one side edge of the tape material 2 is edge-sewn, the tape material 2 is wound around the winding core 86 (FIG. 9), and the wound tape material 2 is passed through the device 10 again, so that both side edges are Weed-woven tape can be obtained. In this woven tape, the inclinations of the sewing thread 5 of the single chain stitched portion 6 on both side edges are substantially the same in a plan view, and can be processed into a woven label 9 (FIG. 3) by cutting each label one by one. In this woven tape, the weft thread of the tape material 2 may be used as the sewing thread 5, and the color and design of the entire tape can be made uniform.

In the edge-sewn tape material 2, one sewing thread 5 forming the single loop stitch portion 6 intersects with the fiber fusion portion 4 at the tape side edge 3 without overlapping, and in reality, the thread loop portion 93.
The sewing threads 5 of each of the above are closely contacted with each other without a gap as shown in FIG. Moreover, since the insertion thread 7 is in contact with the fiber fusion portion 4 in the single loop stitch portion 6, the irregularities and roughness of the tape side edge 3 due to the fiber fusion portion 4 are eliminated, and the feel of the tape is significantly improved. The insertion thread 7 is concealed by the sewing thread 5 of the single-loop stitch portion 6 even if the insertion thread 7 is significantly different from the tape weft thread in terms of its brightness, so that the appearance of the tape is not impaired.

Although the double-sided sewing device 118 shown in FIG. 10 has a structure in which two devices 10 of FIG. 4 are combined, the first sewing machine 120 feeds the tape material 2 in the arrow direction of FIG. 10, that is, to the left. The tape feeding direction is opposite to that of the sewing machine 14 (FIG. 4). In addition, the second sewing machine 12

In the second sewing machine 122, the insertion thread 7
Is fed from a spool (not shown) located above the device 118 and is fed through the yarn tensioner 110 and the yarn guide 112, as in the device 10 described above. Insert thread 7
Runs further in parallel with the tape side edge 3 through a through hole of a thread guide rod (not shown), is wrapped in the single loop stitch portion 6 by the turning of the thread ring portion, and passes through the presser foot 114. Then, it comes into contact with the side edge, that is, the fiber fusion portion 4. As shown in FIG. 2, the insertion yarns 7, 7 on both side edges are interposed between the sewing thread 5 of the single loop sewing portion 6 and the fiber melting portion 4, so that the fiber melting portion 4 breaks or fluffs the sewing thread 5. To prevent almost completely.

As shown in FIG. 12, an opening 142 is provided in the table 140 below the roller pair 138 on the sewing machine 120 side. The tape material 2 picked up by the roller pair 138 is sent out to the lower side of the table 140 through the opening 142, is wound around the rollers 144 which can move up and down from both rollers, and further, the upper horizontal roller 145 and the horizontal guide member 1.
Vertical rollers 148, 15 on the sewing machine 122 side.
Send to 0. By the vertical movement of the roller 144, the difference in the feed speed between the sewing machines 120 and 122 can be alleviated. On the sewing machine 122 side, on the other hand, an opening 156 is provided in the table 154 in the vicinity of the lower part of the take-up roller 152, and the tape material 2 picked up by the roller pair 152 is sent out to the lower side of the table, and the tape material 2 is picked up in the same manner as the device 10. It winds up on a winding core through a roller (not shown) that can move up and down.

In the double-sided sewing device 118, the winding core 158 of the tape material 2 is placed on the circular seat of the mounting table 124, and the tape material 2 is pulled out from the winding core and 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 2, and intermittently feeds the tape material 2 to the left by the presser disk 96, while the single chain stitch portion 6 ( 2) is formed and the insertion thread 7 is linearly enclosed. The tape material 2 sewn on one side is pulled in the horizontal direction via the guide member 136 and the roller pair 138, and further the roller 1
44, 145 and the guide member 146 send out in the horizontal direction.
The tape material 2 stands on the vertical roller 148 in the longitudinal direction, and at this time, the original single loop stitch portion 6 is located on the lower side. Further, the guide member 162 feeds the tape material 2 into the sewing machine 122, and intermittently feeds it to the right with the presser disc 164 to form the other single chain stitch portion 6 and enclose the insertion thread 7. The tape 1 whose both edges have been sewn is taken up by the rollers 152, 152 and wound around the core under the table 154.

In order to obtain the woven tape 1 shown in FIG. 1, the tape material 2 is run once by the double-sided sewing device 118 (FIG. 10). On both side edges of the tape 1, one sewing thread 5 forming the single chain stitch portions 6, 6 is a fiber fusion portion 4 of the tape side edge 3.
And the seams thereof continuously exist without being superposed, and the thin thread 5 also tightly covers the fiber fusion portion 4. The tape 1 can be used as it is as long as it is a series of patterns. If desired, the tape 1 is resin-processed with chemical glue or the like to adjust the shape.

When the tape 1 is heat-cut in the lateral direction for each pattern or character, the woven label 9 illustrated in FIG. 3 can be formed. The woven label 9 is end-held at the position indicated by the alternate long and short dash line in FIG. 3 in the subsequent folding step. At this time, resin processing may be performed in advance, and thereafter, heat treatment may be performed in the lateral direction for each label by a separate heat cutting device. The woven label 9 thus obtained is subjected to end-holding in a subsequent folding step and then pressed.

On the other hand, as illustrated in FIG. 14, by using the overlock sewing machine 170, the fiber-melted portions on both side edges of the tape material 166 (FIG. 13) are sewn to the edge stitching portion 16.
You may wrap it with 0,160. When forming the hemming portion 160, a linear insertion thread 164 is enclosed therein so as to be in contact with the fiber fusion portion. The supply mechanism of the insertion thread 164 is
Functionally similar to that disclosed above. The hemming device 168 has right and left overlock sewing machines 170, 170 at predetermined intervals, and a tape speed adjusting mechanism 172 is installed between the sewing machines. A sewing thread having a color suitable for the ground color of the woven tape 162 is threaded through the known overlock sewing machines 170, 170 to form the tape material 16
We sew each one side edge of 6.

The speed adjusting mechanism 172 includes a weight roller 174 that can move up and down, and has a detection mechanism that detects the tension of the tape material 166 fed to the roller 174 and moves the roller up and down. Due to the existence of this detection mechanism,
The tape material 166 passing through the roller 174 maintains a constant speed. As a result, the front and rear overlock sewing machines 17
Even if there is a slight difference in tape feeding speed between 0 and 170, the speed of the tape material 166 fed to the rear overlock sewing machine 170 is always constant, and the rear sewing machine 170 can maintain stable thread sewing.

The woven tape 1 that has passed through the edge sewing device 168
62 (FIG. 13) is formed with closely edging portions 160 along the fiber fusion portions on both side edges, and both fiber fusion portions are wrapped by the edging portions 160, 160. By wrapping the fiber fusion parts on both side edges of the tape with the sewing thread of the edge seam 160, it can be used as it is as a woven ribbon. With this woven ribbon, it is possible to change the design by changing the count and color of the sewing thread of the edge sewing portions 160, 160, or to add a decorative effect by pattern sewing.

In the woven tape 162, when the edge stitching portion 160 is formed, a linear insertion thread 164 is enclosed therein so as to be in contact with the fiber fusion portion. The insertion yarn 164 is made of a large number of twisted yarns, and is manufactured by kneading a predetermined amount of an inorganic fluorescent substance having a particle size of about 1 to 3 μm and spinning it. For example, as the fluorescent substance, a red coloring material (composition: Y ₂ O) is used. ₂ S: E
u) is used. The insertion thread 164 emits red light when irradiated with black light, has almost no afterglow, and is colorless when irradiated with ordinary sunlight or fluorescent light.

To obtain a woven label from the woven tape 162, the woven tape is further heat-cut in the lateral direction for each label by a separate heat cutting device (not shown). The obtained rectangular woven label is subjected to end-holding or center-holding in a subsequent folding step and then pressed. After the folding process, the woven label is sewn to a predetermined portion of clothing such as a blouson or a cutter shirt.
