Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape having a lace-like pattern and a method for manufacturing the same. This tape can be used, for example, as a decorative frill or ribbon for handicrafts.

[Prior Art] As tapes having conventional patterns, knitted fabrics or embroidered fabrics made of lace thread or the like are well known.

In addition, so-called chemical lace-like products are also known, which are obtained by applying a welding process to the joints of the threads of a woven fabric to prevent fraying, and then dissolving the pattern using a chemical or the like.

[Problems to be Solved by the Present Invention] Although the former knitted fabrics and embroidered fabrics using lace yarn have a luxurious feel, they cannot be mass-produced and tend to be expensive.

The latter technique is cheap and suitable for mass production, but is not suitable for drawing delicate patterns.

The present invention has been made to solve these problems of the prior art.

A specific object of the present invention is to have a delicate lace-like pattern,
Another object of the present invention is to provide a tape that can be mass-produced.

Another object of the present invention is to provide a method for manufacturing a tape having a lace pattern as described above.

[Means for Solving the Problems] The tape having a lace-like pattern of the present invention is formed by forming a perforated pattern and a stamped pattern on a fabric tape body having high frequency fusion or ultrasonic fusion properties. Features.

Further, the method for manufacturing a tape having a lace-like pattern according to the present invention is characterized by having the following steps.

That is, (a) superimposing a support sheet on a fabric tape having high frequency welding or ultrasonic welding properties to create a fabric consisting of at least two layers; (b) forming a perforation pattern and a stamped pattern on the tape body; radiating high frequency or ultrasonic waves to the fabric on the pattern imparting means to continuously cause high frequency fusion or ultrasonic fusion to form a lace pattern; (c) a tape having a lace pattern; This is the step of peeling off the support sheet from the support sheet.

Examples of fabrics having high frequency welding properties include soft vinyl chloride, nylon, vinylidene chloride, hard vinyl chloride, and acetate film.

In addition to the above-mentioned materials, fabrics with ultrasonic bonding properties include
Most thermoplastic polymeric materials can be used.

The support sheet is peeled off in the final process and does not remain on the product. As the material for this sheet, for example, polypropylene film, cellophane (trademark), and paper can be used.

As the high frequency radiating device, for example, a commercially available high frequency welder or high frequency sewing machine can be used. As the ultrasonic emitting device, for example, a commercially available ultrasonic welder or ultrasonic sewing machine can be used.

The pattern imparting means is provided with protrusions for forming a perforation pattern and a stamping pattern on the tape body.

This protrusion can be provided on the cradle of a high-frequency welder or the feed roller of a high-frequency sewing machine. Similarly, this protrusion can be provided on the pedestal of an ultrasonic welder or on the feed roller of an ultrasonic sewing machine. For making holes, it is preferable to use protrusions with approximately the same thickness as the main tape, and for making stamped patterns, it is preferable to use protrusions with a thinner thickness.

As for the hole punching pattern, holes of various sizes can be appropriately arranged on the tape. As the stamped pattern, for example, an animal/plant pattern or a geometric pattern can be adopted.

The fabric consisting of the main tape and the support sheet is continuously fed into a high frequency or ultrasonic radiation device.

Therefore, the main tape undergoes high frequency welding or ultrasonic welding to form a lace-like pattern in accordance with the pattern imparting means.

In the final step of peeling off the support sheet, the fabric from the holes in the tape remains on this sheet so that it will not be scattered around the work area.

[Function] According to the present invention, a tape having a delicate lace-like pattern as the pattern imparting means can be easily obtained by high frequency welding or ultrasonic welding. Even if you make a hole, the area around the hole will harden, so it will not fray from there.

[Example] Hereinafter, the present invention will be described in detail based on the accompanying drawings.

The tape 1 shown in FIG. 1 is an embodiment of the present invention.

The tape body 2 is woven from chemical fibers such as nylon, and is long and narrow as a whole.

In this embodiment, the width is approximately 3 cm. A large number of small holes 3 are punched in the edge of the main body to form a line pattern. Large and small patterns 4 are punched here and there in the center of the main body, and stamped patterns 5 of animals, plants, geometric figures, etc. are formed.

As shown in FIG. 2, most of the main body 3 and 4 pass through the front and back, but the stamped pattern 5 is depressed only on the surface.

A method of manufacturing a tape having a lace-like pattern will be explained based on FIGS. 3 and 4.

FIG. 3 is a schematic diagram of a pattern imparting process using an ultrasonic sewing machine. In this figure, numeral 6 is a horn of the ultrasonic sewing machine, and 7 is a feed roller. The tape body 2 is fed between the horn 6 and the feed roller 7, and the horn 6 emits ultrasonic waves.

It is necessary to overlap the support sheet 8 on this tape body in advance to form at least two layers of fabric.

The tape body 2 is made of a fabric having ultrasonic welding properties, such as nylon. For example, polypropylene is used as the support sheet 1-8.

As clearly shown in the enlarged view of FIG. 4, the feed roller 7 is engraved with pattern-imparting means such as animal and plant patterns and geometric patterns. The pattern imparting means are protrusions, and the protruding portions 9 having approximately the same thickness as the tape body 2 penetrate through the tape body 2 and become through holes 3 and 4.

The protruding portion 10 having a thickness smaller than that compresses the tape body 2 and forms the stamped pattern 5.

These patterns 3, 4.5 in the tape body 2 are hardened by ultrasonic radiation, so that they form a lace-like pattern. The parts 3 and 4 where holes are made are hardened around the holes, so they will not fray from there. The pressed portion 5 is compressed and fused and becomes somewhat transparent.

Although not shown, the same effect can be obtained by using a high-frequency welder, a high-frequency sewing machine, or an ultrasonic welder. When a high frequency welder or an ultrasonic welder is used, the protrusions of the patterning means can be provided on the pedestal.

After forming the lace-like pattern on the tape in this way, the support sheet 8 is peeled off from the tape 1.

The perforated parts 3 and 4 of the tape body 2 remain attached to the support sheet 1 8 and are not scattered in the work area.

[Effects of the Invention] Since the present invention has the above-mentioned configuration, a tape having a delicate lace-like pattern corresponding to the pattern imparting means can be obtained.

Further, since the lace pattern is formed by high frequency welding or ultrasonic welding, it can be obtained easily and inexpensively.
