Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cloth display tag or a cloth tag attached to clothing or the like.

[0002]

[Prior art]

 Clothes are sewn with cloth display tags or tags (hereinafter referred to as display tags) or welded with hot-melt adhesive. When manufacturing this display tag, the material, precautions, manufacturer name or product number, etc. are printed on a cloth tape made of synthetic fiber fabric, and this is printed with an electrothermal melting and cutting machine using nichrome wire. It is heat-cut in the width direction at a predetermined length and cut into individual display tags.

[0003] In the heat-cut display tag, a cutting line formed by melting and cutting in the width direction of the cloth tape is formed. Since the cutting line is obtained by locally melting a synthetic fiber fabric, A lump of synthetic resin is formed linearly. Therefore, the cutting line is considerably harder than the other cloth portions.

[0004]

[Issues to be solved by the invention]

 As shown in FIGS. 4 (A) and 4 (B), a display tag 22 having a cutting line 21 obtained by heat-cutting a cloth tape 20 made of a synthetic fiber fabric as described above and heat-cut is used for the display tag 22. Since the portion obtained by melting and cutting the fiber woven fabric in a linear shape is solidified, the width of the portion of the melted cutting line 21 is large or the cloth tape 20 is formed of a thick synthetic fiber woven fabric. If the heating temperature of the nichrome wire of the heat cutter is higher than necessary and the amount of the cloth tape melted is large, a hard and thick cutting line 21 is formed or the wire is hardened and deteriorated as if carbonized.

[0005] The display tag 22 manufactured in the above cutting process is often fixed to the back portion of a case where the display tag 22 is fixed to a collar portion of a neck of clothing or underwear such as pants. Also, when worn on a shirt, underwear, or the like, such as an outerwear, even if the cutting line 21 is formed by heat cutting with electroheating like a display tag 22 made of a conventional cloth tape 20. There was relatively no problem.

However, in the case of underwear that directly contacts the skin, particularly underwear that directly contacts a soft body such as an infant or a woman, the cutting line formed by solidifying the synthetic resin as described above. 21, especially the edges or corners of the cutting line may damage the skin. In particular, when the tape is cut by a heated nichrome wire, a sharp lump is formed at the end of the cut line depending on the heating temperature of the nichrome wire, the usage time, and the like. In addition, when this cutting line ends at the edge of the width of the display tag, a sharp corner 21a is formed, which may damage the skin.

The present inventor has tried various cutting methods in order to solve such a defect of the cloth display tag by the conventional electrothermal heat cut. If the cloth tape is simply cut with scissors, a hard cutting line is not formed as described above, but the fibers at the cut end of the display tag are not cohesive and are broken during use. Requires end treatment. In addition, heat cutting can efficiently manufacture, but has problems as described above.

[0008] The method of thermally cutting the cloth tape such as the heat cut is advantageous from the manufacturing process of the display tag because the cutting operation and the end treatment are performed at the same time. Problem.

The inventor tried a method of cutting a synthetic fiber cloth tape by applying ultrasonic waves, and found that many fibers constituting the cloth tape could be cut by ultrasonic vibration. Was done. Moreover, the cut portion was as soft and pleasant as the original fabric. In addition, when the cloth was pressed against this cutting line and rubbed, it was confirmed that there was no breakage.

[0010] Considering the cutting line, a pressing force and an abrasion force due to ultrasonic vibration are generated in the synthetic fiber by ultrasonic waves, and some fibers are softened and cut off, or a part is melted. However, it was confirmed that the melting range was a very small range in which the pressing force of the ultrasonic wave acted, and did not extend to other portions. The limitation of this melting range is important in the present invention and means that it does not form a hard cutting line as in conventional heat cutting.

When the ultrasonic wave is applied to the synthetic fiber fabric, a part of the cloth is softened according to the frequency and intensity of the ultrasonic wave and the state of pressing between the ultrasonic horn and the pedestal. In addition, a state of melting occurs, and further, a state in which the whole is softened or melted and cut in the thickness direction of the cloth changes variously.

[0012] Even in the case of cutting, a large amount of heat is not applied to a large area as in the case of cutting by heat cutting, and heating is limited to a small area where ultrasonic waves are transmitted. Also, in the molten state, the parts subjected to the pressing force do not melt at once, but the fibers are softened slowly in a small number of areas subjected to high frictional force or joined by melting. Do you get it.

FIG. 4B shows an end portion of the cloth tape 20 (display tag 22) formed by the conventional heat cutting, and a cutting line 21 indicates that the resin constituting the synthetic fiber is melted and hardened. However, even if this portion is formed into a thin linear shape, the hardness cannot be reduced.

On the other hand, FIGS. 5A and 5B show an end portion cut by an ultrasonic cutting machine, and the cutting line 7a of the cloth tape 1 is naturally cut as a whole. Although the whole is partially melted due to heat generated by friction and is united with each other, some of the fibers 1a are pressed together in a softened state, and a small range of fibers is kept in a molten state while maintaining softness. It was confirmed that they were adhered. In addition, the ends of the fibers in a small area are pressed and joined under heating, so that the cut line 7a of the cloth tape 1 does not fall apart.

[0015] This invention is based on the characteristics of cutting with friction heating of fibers by ultrasonic waves as described above, that is, the fact that fibers cut by softening by friction heating are joined by a small number of fibers, and heat itself is reduced. Since it is not added to the cloth tape all at once, the molten state does not propagate rapidly to the adjacent fibers, but the heat energy generated by friction is limited to the part where ultrasonic waves act. It is a thing that utilizes that.

The present invention utilizes the fact that the cutting line 7a formed by ultrasonic cutting is soft, and that no sharp hard corner 21a is formed at the corner 7c as shown in FIG. 4B. It is intended to provide a display tag made of cloth.

Further, as shown in FIG. 6, by cutting the corner portion 7b so as to form an arc or oblique shape, a soft and skin-friendly cloth display tag is provided as a whole.

[0018]

[Means for Solving the Problems]

 The cloth display tag according to the present invention is obtained by paying attention to the characteristics of the ultrasonic wave, and is configured as follows.

1) A fabric tape of a synthetic fiber or a mixed fiber mainly composed of a synthetic fiber, which has been subjected to predetermined printing, is cut in a transverse direction at a predetermined length by an ultrasonic cutter.

[0020] 2) The cutting line is constituted by a straight line section cut in the width direction of the textile tape, and an inclined section (corner) extending from the straight line section to both side edges of the textile tape. And

3) The inclined portion is formed in an arc shape or a linear shape.

4) The material of the display tag is characterized in that the synthetic fibers are polyester fibers, nylon fibers, or polypropylene fibers.

5) The cutting line cut by the ultrasonic cutting machine is characterized in that some of the fibers are joined or melted and joined in a softened state at the cut end.

[0024] This invention is based on the idea that when fabricating a display tag made of tape made of a synthetic fiber woven fabric, the ultrasonic energy is used to cut the fiber together with a small range of heat of abrasion, and the heat generated at that time. The present invention relates to a display sign made of cloth that utilizes welding characteristics by softening or welding by local melting.

[0025] The cloth display tag according to the present invention forms an ultrasonic horn or a cutting line projecting in area on the pressing table opposed to the ultrasonic horn, and preferably, the cutting line is a corner of the display tag. The portion corresponding to the portion is formed in an arc shape.

[0026]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a cloth tape 1 made of a synthetic fiber woven fabric for forming a display tag T, which is printed at predetermined intervals (material name, product number, precautions, manufacturer name, telephone number). 2), and a portion indicated by a chain line 3 between the prints 2 indicates a line (7a in FIG. 5) to be cut by the ultrasonic cutting machine.

FIG. 2 is a plan view showing a main part of an ultrasonic cutting machine 4 which is a part of a manufacturing apparatus of the display tag T. FIG. The coil constituting the vibrator 13 is energized by 12 to generate a vibration of a predetermined frequency, and the vibration is transmitted to the pedestal 5 via the cone 14, and the pedestal 5 is oscillated by an ultrasonic wave. It has become.

The cutting blade 6 is pressed against the receiving table 5 with a predetermined pressure as shown by an arrow P to melt the woven fibers on the cloth tape 1 by the pattern 7 of the cutting blade 6 and by ultrasonic vibration. Disconnect. A cutting pattern 7 is formed on the cutting blade 6 as described later, and a cutting portion 7a is formed according to the pattern 7.

As shown in FIG. 7 (A), the cutting pattern 7 is formed in a Y-shape with a straight portion A and curved portions B, B on both sides of the tip surface 6a of the cutting blade 6. The straight line portion A is a cutting line that is cut for each display tag T, and the curved portions B and B are portions that cut the corners of the display tag T so as to cut out round. The curved portions B, B mean a corner or an inclined portion.

As shown in FIG. 7 (B), the cutting pattern 7 has a curved portion B, B in which a portion cutting the corner of the display tag T is formed, or a linear inclined portion as shown in FIG. 7 (C). C and C can be used, and if the corners of the display tag T are not damaged, the underwear can be manufactured.

The size and shape of the cutting pattern 7 may be individually determined according to the width of the cloth tape 1, the characteristics of the fabric, and clothing such as underwear using the display tag T.

In the present embodiment, an example in which the cutting pattern 7 is formed in a Y shape is shown. It is also possible to prepare a cutting blade 6 having a B or an inclined portion C and change the process so as to cut the corner in multiple stages.

As described above, when the cloth tape 1 is supplied between the cutting blade 6 and the receiving table 5 using the ultrasonic cutting machine 4 and the ultrasonic wave is applied between the two, FIG. (B) As shown in (B), the cutting line 7a is pressed while the fibers are softened, or a small area of the fibers is melted and joined, and the portion of the cutting line 7a is the original fabric. It has been confirmed that it has the feel of

The cutting line 21 of the display tag 22 by the conventional heat cut shown in FIG. 4 is solidified as a whole, and in particular, the corner 21 a is sharp as shown in FIG. In the device of this invention, as shown in FIG. 5 (B), the corner 7c does not form a hard lump of synthetic resin at all.

In particular, in the case of a display tag attached to underwear for infants and women, it is preferable that the corners are further processed to be curved or inclined. The display tag T which is gentle on the skin is manufactured by forming the corner 7b in an arc shape as shown in FIG. 6 (A) or the corner 7d which is cut diagonally as shown in FIG. 6 (B). can do.

In the meantime, in the ultrasonic cutting machine shown in FIGS. 2 and 3, the cutting pattern 7 is formed on the receiving table 5 side, and it is not necessary to provide the cutting pattern 6 on the cutting blade 6 side. Further, it is best to process the entire cutting line 7a in one step, but it is also possible to optionally process the cutting line 7a in two or three steps.
