JPH03210201A - Manufacture of instep of shoe - Google Patents

Abstract

PURPOSE:To obtain a completely finished instep completed product by a simple work by sticking a lunar core with an adhesive agent to the heel part of the back leather separated from the surface instep leather before it is completed to make the instep, superposing the surface instep leather on the back leather and seaming their upper part opening peripheral edges, thereafter, executing lifting by a last and forming the heel. CONSTITUTION:Before it is completed to make the instep, a lunar core 3 impregnated with an adhesive agent is stuck to the heel part of the back leather 2 separated from the surface instep leather 1. Subsequently, the surface instep leather 1 is superposed on the leather 2 to which the lunar core 3 is stuck and their upper part opening peripheral edges 1', 2' are seamed. Next, lifting is executed by a last and the heel is formed. In that case, by executing the forming by applying heat, the lunar core 3 adheres completely to the back leather 2. In such a way, a process for inserting the lunar core 3 between the surface instep leather and the back leather of the instep completed product can be eliminated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing shoes, particularly uppers for women's shoes.

[Prior art] When manufacturing shoe uppers, conventionally, the cut upper skin and lining skin are overlapped and sewn around the upper opening periphery of the heel. In the next step, a moon-shaped core was inserted between the skins, and then a wooden mold was used to create the heel part of the finished armor product.

[Problem to be solved by the invention]

However, since the relatively long moon-shaped core was manually inserted into the heel of the finished armor product while being applied with adhesive, it was time-consuming and did not improve work efficiency, and it was not possible to insert it completely. This tendency was particularly strong as the moon-shaped core becomes longer when the heel is higher, as in women's shoes.

An object of the present invention is to provide a method for manufacturing shoe uppers that is simpler and allows a perfectly finished finished upper product to be obtained.

[Means to solve the problem]

In order to solve the above object, the method for manufacturing a shoe upper according to the present invention involves attaching a moon-shaped core with adhesive to the heel part of the lining, which is separate from the upper skin, before the manufacturing of the upper is completed. The lining is pasted on, the outer skin is superimposed on the lining, and the periphery of the upper opening is sewn, and then the heel is formed by hanging with a wooden mold.

〔Example〕

Figures 1 to 3 show the manufacturing sequence of a particularly long women's shoe upper with a moon-shaped core.

In the method of manufacturing a shoe upper according to the present invention, before the manufacturing of the upper is completed, the heel portion of the lining 2 (Fig. 2), which is separate from the upper skin 1 (Fig. Attach the moon-shaped core 3 impregnated with the agent as shown in Figure 2. Then, the outer skin 1 is superimposed on the inner skin 2 with the moon-shaped core 3 attached, and the upper opening peripheries 1' and 2' are sewn with sewing thread 4 as shown in FIG. Next, use a wooden mold to shape the heel. At this time, since the molding is performed by applying heat, the moon-shaped core 3 completely adheres to the back skin 2.

〔Effect of the invention〕

In the method for manufacturing shoe uppers of the present invention, a moon-shaped core with adhesive is attached to the heel part of the lining, which is separate from the outer skin, before the manufacturing of the upper is completed. The leathers are overlapped and the edges of their upper openings are sewn together, and then they are hung using a wooden mold to form the heel, so a moon shape is created between the upper skin and the inner skin of the finished product, as in the past. There is no need for the troublesome process of inserting the core (this reduces work time and
The insertion of incomplete moon-shaped cores is eliminated, and a perfectly finished and good finished armor product can be obtained.
