Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hook-and-loop fastener mainly used for clothing, covers, bags, bags, etc.

[Conventional technology]

Conventionally, tape-shaped continuous surface fasteners have been known to have cut-off broken lines so that they can be cut and separated at predetermined lengths. (For example, Jitsukaiaki
(Refer to Publication No. 53-140760) [Problem to be solved by the invention] However, in conventional products with broken cut lines for separation cutting, it is difficult to identify the position of the broken cut lines because of the loops and hooks that stand up on the surface of the hook and loop fastener. Also, since no fraying prevention means are provided, the cut ends tend to fray, and furthermore, in the uncut portion on the broken line, the thread that is the material of the hook and loop fastener is pulled out when it is cut and separated. It has been difficult to obtain a cut surface fastener with good appearance.

Therefore, the present invention solves the conventional problems and provides a hook-and-loop fastener of a predetermined length that makes it easy to identify the cutting position, allows easy cutting of the tape with bare hands, and prevents the cut ends from fraying. The purpose of this invention is to provide a hook-and-loop fastener that can be used.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention is a tape-shaped continuous surface fastener, which is formed by melting and solidifying the surface fastener in a concave shape from the surface at every predetermined length in the width direction. Separation cutting grooves 5 and 5a having thin bottoms that are thin enough to be torn apart are provided so that cutting can be performed easily and with good physical condition.

〔Example〕

An embodiment of the present invention will be described. There are various kinds of surface fasteners, but the typical one is a loop tape in which countless fine loops 3 made of thin plastic thread are densely grown on the top surface of a base fabric 2 knitted or woven with synthetic fiber yarn, as shown in Figure 4. , similarly, it is made of a hook tape in which countless fine hooks 4 are densely protruded, and the loop surface of this loop tape and the hook surface of the hook tape are used in close engagement with each other.

In the present invention, as shown in FIG. 1, the loop tape and the hook tape of the hook-and-loop fastener 1 are separated and cut into grooves 5 according to the required lengths according to the intended use, such as clothing covers, bags, etc. When the fabric is formed and sewn, the loop tape and the hook tape are torn off and used at the thin bottom of the groove.

The groove 5 for separation and cutting is made by cutting a loop (or hook) made of plastic and a base cloth made of synthetic fiber into a narrower shape from the surface of the tape using an electric heating roller, an electric heating edge, an ultrasonic wave, etc. A thin wall with a moderate thickness that cannot be torn off by handling such as winding onto a bobbin, packaging, or transportation, but can be easily torn with bare hands. The bottom part of the part is formed with a width that is not completely hidden by the loop (or hook), and the groove 5 is formed into a V-shaped groove that widens toward the surface. The melted and solidified portions become translucent, exhibiting a different coloration than other unmelted tape portions, and are not completely hidden by loops (or hooks), making it easy to identify the grooves. When forming a V-shaped groove, loops 3 (or hooks 4) located on both sides of the groove 5 as shown in FIG.
If the tape is heated so that it is tilted toward the side opposite to the groove 5, the groove can be more easily identified, and the appearance of the hook-and-loop tape after cutting will also be improved. Note that although the shape of the groove for separating and cutting is V-shaped in FIGS. 1 and 2, it may also be a U-shaped groove 5a as shown in FIG. Further, although the grooves are formed in a direction perpendicular to the length direction of the tape, grooves may be formed in an oblique direction or other directions depending on the purpose, the place of use, etc.

A loop tape and a hook tape, in which grooves 5 and 5a for separation and cutting are provided in the width direction at predetermined lengths, are each wound onto a bobbin 6 as shown in FIG. 5, packaged, and sent to a sewing factory. When shipped to a retail store and used, the loop tape and hook tape are pulled out from the bobbin 6 and torn off by hand at the grooves for separation and cutting, and the cut loop tape and hook tape are used as a set, making it very easy to handle hook and loop fasteners. The tape will not bend or twist during transportation, so the appearance of the product will not be damaged.

[Effect of idea]

The present invention consists of a tape-shaped continuous surface fastener, which is formed by melting and solidifying it in the width direction at predetermined lengths, and has a thin section at the bottom that is thin enough to be torn off. By providing grooves, the tape can be cut very easily with bare hands, and since the cut ends are in a molten solid state, loops, hooks, base fabrics, etc. will not fray, and it is easy to cut the tape separately. Because the grooves are melted and solidified, they are translucent and have a different coloration from other tape parts, and because they are not hidden by loops or hooks, the grooves can be immediately identified, making them easy to use when cutting with scissors, cutters, etc. There is no need to measure the tape each time, it can be easily cut without any cutting equipment, and it greatly improves the efficiency of the sewing process, and since it can be handled as one long continuous tape, it can be wound onto a bobbin etc. This makes it possible to transport and handle the hook-and-loop fastener very conveniently, and since the tape does not bend or twist during transport, the appearance of the product is not damaged.
