JPH0874111A - Production of shoulder pad for western style clothing - Google Patents

Abstract

PURPOSE: To provide a production method not to develop spindle-shaped cut extra parts during conventional shoulder pad production processes, thereby obviating the waste of a shoulder pad material to reduce production cost. CONSTITUTION: This shoulder pad for western style clothing is obtained by dividing a shoulder pad material into two. Specifically, the shoulder pad material 10 is molded in such a way that both sides of the material are molded with the horizontal centerline thereof as boundary slantly upward to provide both sides of the centerline with a laterally symmetric slant parts 20 inrestorable at normal temperatures, and both the sides of the centerline are bent downward and toward the centerline so as to each form an arc-shaped cross section to furnish a bent part 22 inrestorable at normal temperatures, followed by cutting the shoulder pad material longitudinally along the centerline.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a shoulder pad for clothes. The present invention relates to a method for manufacturing waste material for shoulder pad, in particular.

[0002]

2. Description of the Related Art A general prior art of this kind is to bend the laminated material for shoulder pads in a generally arcuate cross section and cut the center portion into a spindle shape with a blade so that the sleeve side is inward when viewed from a plane. This is a step of manufacturing a pair of left and right shoulder pad that has a circular arc shape. Therefore, the spindle-shaped cut portion becomes a surplus portion 36, and eventually the material is wasted (see FIG. 6). The surplus part is 15
It is said to occupy about 20%, and it has been a bottleneck in the manufacturing process of the shoulder pad for a long time, and its improvement measures have been desired.

For example, the invention described in Japanese Examined Patent Publication No. 1-12845 is known, but although the improvement of the shortening of the manufacturing process has been made, the material is still wasted.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks of the prior art. The object of the present invention is to provide a spindle-shaped excess cut in the conventional shoulder pad manufacturing process. The purpose of this is to prevent the parts from being generated, to reduce the waste of the shoulder pad material, and to reduce the cost.

[0005]

In order to achieve the above-mentioned object, the present invention has a basic structure in which a shoulder pad pad material is divided into two parts, and a shoulder pad pad for clothes is manufactured. By forming the working material with the center line in the horizontal direction as a boundary, with its both sides directed obliquely upward, both sides of the center line are provided with symmetrical sloping portions that do not restore at room temperature, and A curved part that does not restore at room temperature is formed by curving both sides in the direction of the center line downwards in a circular arc shape with the center part as the boundary, and then the shoulder pad material is formed along the center line. It employs a process of separating the inclined portion by cutting in the vertical direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the embodiments of the present invention will be described with reference to FIGS.

In the structure of the present invention, the type of the shoulder pad material 10 and the number of layers thereof are not concerned. It is also possible to use a single material such as urethane or foam. As is generally practiced, stacking 2-3 to 10 or more sheets is adopted depending on the application, and the inventor naturally plans this. In this embodiment, the upper and lower layers are composed of the surface layer material 12, the back layer material 14, and the filler material 16 inserted between them, but this is merely an example for convenience of description. It will be easily understood.

In the present invention, as will be described later, a step of forming the shoulder pad material 10 into a certain shape so as not to be restored at room temperature is adopted during the manufacturing process. Therefore, when the three types of materials forming the shoulder pad material 10 are natural fibers, it is desirable that at least one type of the materials be subjected to thermosetting resin processing or thermoplastic resin processing. Of course, such a process may be a commonly adopted method. For example, a thermosetting resin or a thermoplastic resin may be applied or sprayed on the surface of the material 10. When synthetic fibers including thermosetting fibers and thermoplastic fibers are used as raw materials, it is not necessary to perform the above-mentioned treatment.

Next, as is apparent with reference to FIGS. 1 and 2, the laminated shoulder pad material 10 is formed in such a manner that both sides thereof are diagonally upward with the center line 18 as a boundary in cross section. On both sides of the center line 18, symmetrical inclined portions 20 that are not restored at room temperature are provided.

In this case, it is appropriate that the inclination angle α between the inclined portions 20 on both sides is approximately 160 degrees.

In addition to the inclined portion 20, the center line 1 is formed on both sides of the center line 18 with the center portion P as a boundary.
The curved portion 22 that is not restored at room temperature is formed by curving downward in the eight directions in a circular arc cross section.

In the method of forming the sloped portion 20 and the curved portion 22 described above, the sloped portion 20 and the curved portion 22 are provided with a concave and convex upper mold 24 and a lower mold 26 having symmetrical shapes, and subjected to a heat squeezing treatment. Done by. In this embodiment, the case in which the inclined portion 20 and the curved portion 22 are simultaneously molded by the molding die 30 is shown, but the invention is not necessarily limited to simultaneously molding both.

The center line 18 side of the inclined portion 20 is a portion to be brought into contact with the sleeve portion side of clothes after use after cutting, and the curved portion 2
Numeral 2 is a portion of the shoulder of the clothes which is brought into contact with the front body side and the back body side. Therefore, the curved portion 22 may be provided by a secondary process other than the molding of the inclined portion 20 after the inclined portion 20 is molded.

As described above, since the material is processed by thermosetting resin or thermoplastic resin, its shape will follow the shape of the molding die by being heated and pressed, and thus the shape of the molding die can be easily adjusted. Does not restore. In this way,
By the heating and pressing treatment, a shoulder pad material 28 formed as shown in FIG. 4 whose shape is not restored at room temperature is obtained.

Then, the formed shoulder pad material 28
Is cut by a blade 38 in the vertical direction along the center line 18 to separate the inclined portion 20.

Here, the laminated shoulder pad material 10
In the cross section, the both sides of the center line 18 are formed diagonally upward with the center line 18 as a boundary, whereby symmetrical left and right inclined portions 20 are provided on both sides of the center line 18, and in addition to the inclined portion 20, Since a curved portion 22 having an arcuate cross section is provided on both sides in the direction of the center line 18 and downwards with respect to the center line P of the center line 18 of the center line 18, the shoulder pad material 28 is placed on the center line 18. By cutting along the longitudinal direction, the shoulder pad 34 can be obtained in which the sleeve-corresponding portion 32 is inwardly arcuate when viewed from the plane.

The shoulder pad 34 is similar to that which has been conventionally obtained by bending laminated shoulder pad materials into a generally arcuate cross section and cutting the central portion into a spindle shape with a blade. There is no problem with the function as.

In this way, the shoulder pad material 28 thus formed is divided into two parts, and a pair of left and right shoulder pad 34 is obtained.

[0019]

Since the present invention has the above-mentioned structure, it has the following effects. Although the spindle-shaped material is wasted in the conventional method of manufacturing the shoulder pad by dividing into two, the present invention does not waste any material, and the shoulder pad can be manufactured at low cost. .
