Abstract

PURPOSE:To manufacture a product of which the corners are seamless with good working efficiency by containing a working process for a wrapping member and a buckle core, a covering process for which the peripheral part of sewing is positioned on the outside of the buckle core, and a holding process for which the buckle core is held with the inner periphery part of both a front member and an inside member. CONSTITUTION:Leather is cut out in the shape of a frame, and a front member 1 and an inside member 2 are separately formed. After they are overlapped so that their surface sides are on the outside, their peripheries are sewed with a thread line 3, and thus a wrapping member 4 is made. On the other hand, a buckle core 6 in the shape of another frame is independently made and a holding groove 5 is formed around the inside thereof. After that, the buckle core 6 is inserted between the front member 1 and the inside member 2, and a peripheral part 7 sewed with the thread line 3 is positioned on the outside of the outer periphery of the buckle core 6. An adhesive agent is filled in the holding groove 5 on the buckle core 6, and both an inner peripheral part 8 of the front member 1 and an inner peripheral part 9 of the inside member 2 are held without falling off.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing a walnut buckle.

[Conventional technology]

Conventionally, as shown in FIG. 8, a belt-shaped knoremi material α2 sewn together at a corner part αυ is folded in half and placed over each side of the buckle core α, and at the same time, the thread shell a. A walnut buckle with a U sewn around the circumference is known.

[Problems that the invention attempts to solve]

When making the base of the buckle described in the above-mentioned conventional technology, the seaming process of the corner part αυ is difficult to work with since the surface (to) 1 is difficult to work with, and the product is produced with traces of the seam left on the corner. There were some unfavorable things like that.

An object of the present invention is to provide a new method for manufacturing a buckle that is easy to work with and can produce a product that does not leave seam marks at the corners.

[Failure to solve the problem]

In order to achieve the above object, the method for manufacturing the packle of the present invention includes cutting a flexible sheet such as leather, cloth, or synthetic resin material into a frame shape to form the front material +1) and the back material (2) in the same manner. , these front materials (11) and back materials (2) are polymerized in a state where the front side faces outward, and in this polymerized state, the outer peripheries of these front materials (1) and back materials (2) are formed into threads (3). ) and the manufacturing process of a frame-shaped buckle core body (6) made of a hard material such as metal or hard plastic and having a clamping tll (5) around the inner binding surface. , The inner diameter hole (1)' of the front material (1) or the back material (2
) is inserted between the front material (1} and the back material (2}) through the inner diameter hole (2)' of the thread (3).
] of positioning the stitched edge (7) on the outside K of the outer circumferential edge of the buckle core body (6);
), the green part (9) is irremovably inserted into the fastening curve (5) of the buckle core (6).

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. First, leather is cut into a frame shape to form a front material (1) and a back material (2) in the same manner. (1), the back material (2) is polymerized so that the front side faces outward, and in this polymerized state, the outer periphery of the front material (11, back material (2)) is sewn with thread (3). Walnut wood (4) is produced.

Separately from this, a frame-shaped buckle core body (6) having a fastening groove (5) formed around the inner circumferential edge surface is made of a metal material and made by pasting.

After that, the buckle core body (6) is inserted through the inner diameter hole (l)' of the front material (1) or the inner diameter hole (2)' of the back material (2).
is inserted between the back material (1) and the back material (2), and the stitched edge (7) formed by the thread (3) is positioned outside the outer periphery of the buckle core (6).

Next, the inner green part (8) of the front material (1) and the inner peripheral edge (9) of the back material (2) are attached to the fastening grooves (5) in the buckle core (6) with an adhesive (not shown). ) was placed in a mold so that it could not be pulled out, and the finished product was obtained by holding it in place.

The present invention provides a means for attaching the front material (11) with an adhesive so that the outer peripheral edge (11' of the front material (11) outside the thread (3) does not crack); In addition, there is a means for cutting and aligning the edge surfaces of both outer peripheral edges Ql (I1'), a means for attaching a stopper, and a means for attaching a lock so that the inner peripheral edge f81 (9) does not come off from the clamp @ (5). Same part of the core (8)
(9) and a means for press-fitting it into the clamp 1m1 (5) may be provided as appropriate.

[Function] and [Effects of the Invention] Since the present invention has the above-described configuration, the seaming process of the corner portion αυ described in the above-mentioned conventional technique can be omitted, and the intended manufacturing work can be simplified. The present invention has an excellent effect of completely achieving the purpose of providing a new method for manufacturing tsukuru, which can produce a product with good elasticity and no seam marks left on the corners.
