Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an adjusting guide tape which constitutes a waist size adjusting means for wearing clothes such as pants and skirts, and a manufacturing method thereof.

[0002]

2. Description of the Related Art Generally known waist size adjusting means is, for example, as shown in FIG. 1, an outer waist band at one or two left and right waist portions (W) of pants (P). (W1) and the inner waist band (W2) are provided with an overlapping part, and a synthetic resin of a predetermined width in which a large number of hook teeth are arranged in a row along the longitudinal direction of the surface facing the outer surface of the inner waist band (W2) Both ends of the guide rail band (R) made by sewing the cloth band (C) to the tape main body only or on the back side of the tape main body are sewn so that the latch teeth forming surface is on the inside. Then, on the guide rail band (R), a slider (S) made of a thermoplastic synthetic resin equipped with a claw that engages with the retaining tooth is attached, and the slider is attached.
(S) is configured to be used by being fixed to the outer waist band (W1).
-13211, Japanese Patent Publication No. 7-93886, and many other publications, publications, and patent publications.

[0003]

The guide rail band (R) described in these publications is a tape made of a synthetic resin which is excellent in flexibility and in which latching teeth are integrally formed along the longitudinal direction of the surface. As a structure in which a cloth material is sewn on the main body to improve the appearance, the cloth material surface is the outer surface, that is, the surface on which the latching teeth are formed as described above. The synthetic resin tape is used as a guide for the size adjusting slider (S) by overlapping the outer surface of the inner waist band (W2) and sewing both ends of the inner waist band (W2) to the inner waist band (W2). Since the main body is flexible, it does not hinder the fitting to the waist, but the thickness of the tape main body is 1.5-2 mm because it is required to have a thickness that does not damage the latch teeth. The thick and tape-based (11) cloth material is sewn between cloth materials. It becomes harder than the garment, which causes a decrease in the sewing work efficiency from the need to sew carefully and surely without causing needle breakage.

Further, the thickness of the tape main body also affects the thickness of the size adjusting slider through which the guide rail band (R) passes, and the thickness increases to give a feeling of discomfort around the waist and also to adjust the size. Since the overlapping part of the outer waist band (W1) and the inner waist band (W2) with the slider attached inside, the swelling from the other waist part surface becomes large, and the sliding contact damage on the inner surface of the outer jacket, If the upper clothes are not worn, there is a risk that the exposed swelling part will be brought into sliding contact with the arm and scratched.

In order to eliminate such a decrease in the sewing work efficiency and the abrasion of the arm, for example, a guide rail band (R) has been developed in which hook teeth are formed on a tape made of nylon cloth by embroidery means, and it is commercially available. Although it has been used, although the decrease in sewing work efficiency has been resolved, the formation of hook teeth by embroidery means
Although it can be done relatively easily with an embroidery sewing machine, the manufacturing efficiency becomes poor and the cost increases, and because the latching teeth are repeatedly engaged with the latching claws of the size adjusting slider, embroidery formed hooks are used. The strength and durability of the teeth are difficult.

According to the present invention, it is possible to secure excellent manufacturability, improve sewing work efficiency, prevent arm scratches, secure the strength and durability of the retaining teeth, and eliminate discomfort during mounting. It is an object of the present invention to provide a guide tape for adjusting waist size and the like and a manufacturing method thereof.
