Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of manufacturing shoes that utilizes a counter inserted into the heel of the shoe.

[Conventional technology]

Conventionally, various types of counters have been used, but all of them have been monolithic (many have a base fabric impregnated with the same type of material).

[Problem to be solved by the invention]

The counter, which is the original function of shoes as described in the above conventional technology, does not allow shoes to be used for a long time (24 to 48 hours).
If the counter was not left in the shoe last, it would not dry and harden, resulting in a defect that would prevent it from being accurate enough to perform its function. In other words, during shoe manufacturing, if the shoe slips off the last in a short period of time, the top line of the shoe or the curved portion of the shoe tends to be deformed, which has always been the subject of complaints.

The purpose of the present invention is to satisfy the requirements for a counter necessary to protect the feet as an essential function of shoes and maintain the shape of shoes, and to solve and streamline problems in shoe manufacturing.

[Means to solve the problem]

In order to achieve the above object, the method for manufacturing shoes of the present invention includes the following steps: impregnating and coating both sides of a base fabric with a different type of resin to obtain a dry and solidified counter; and immersing the counter in a solvent. The step of inserting the counter into the heel part after immersing it in this solvent and molding it, and the step of removing it from the mold when one of the foreign resins has hardened as the solvent evaporates, are carried out in this order. It is.

〔Example〕

To explain embodiments of the present invention with reference to the drawings, woven fabric (cotton fabric, warp thread number 20, weft thread number 10)
Alternatively, one side of the base fabric 1 made of nonwoven fabric (polyester long fibers) is impregnated with a rubber material (natural rubber latex with a vulcanizing agent added) 2 that makes the shoes soft and easy to wear, and the shoes are made into a shoe last. In order to remove the shoe from the shoe last in a short time while it is inserted in the shoe, it is dried in 3 to 5 hours, and the other side of the base fabric 1 is dried for 24 to 48 hours in order to meet the conventional counter requirements. The counter is constructed by impregnating a hard resinous material (high styrene emulsion) 3 which can be made and air-dried in a thick manner and then drying and solidifying it.

Next, the counter is immersed in a solvent, and after being immersed in the solvent, the counter is inserted into the heel part and molded. After drying for 3 to 5 hours, a molding process is performed to complete the shoe.

[Effect]

The rubber material 2 serves the function of making it possible for the shoe to slip out of the shoe mold in a short time, and the hard resin material 3 serves the original function of the shoe (protecting the foot when wearing shoes and maintaining the shape of the shoe). ), and the rubber material 2 assists the hard resin material 3 to function sufficiently, and is a film that is difficult to dissolve.

That is, in order to incorporate different purposes and properties into a single counter, the above problem cannot be solved unless the counter is a double-faced counter, which is not found in conventional counters.

〔Effect of the invention〕

Since the present invention has the above-mentioned structure, it not only has the remarkable effect of being able to quickly release a shoe with a soft top line and a firm rise and curve from the shoe last, but also has the following advantages: It also has the effect of

Note 1: The shoe manufacturing process has been shortened and production control has become easier.

2 Maintenance within the factory (reduction and organization of factory space)
, and their work consciousness increases.

3. Due to the tendency to produce a wide variety of products in small quantities, costs will be reduced due to an increase in the number of types of shoe lasts.

4. Warehouse and stock of shoe lasts will be reduced.

5. Conventional counter materials were expensive because they relied on imported products, but the counter of the present invention is made entirely domestically, so costs can be significantly reduced.

6. The counter of the present invention has a double-faced structure, and only the square and the rubber material 2 remain around the counter, so this remaining part is fused to the leather and has the advantage that there is no difference in level caused by the counter.

Claims (1)

[Claims] 1 A process of impregnating and applying a different kind of resin on both sides of the base fabric to obtain a dry and solidified counter, a process of dipping this counter in a solvent, and inserting the counter after being dipped in this solvent into the heel part. 1. A method for manufacturing shoes, which comprises sequentially carrying out the step of molding and molding, and the step of molding when one of the different resins has hardened as the solvent evaporates.
