Medium insertion and method for mfg. shoes

Abstract

The invented shoe middle pad is that on the mounting surface of shoe middle pad which is facing to the middle sole, a detachable dual surface adhesion belt is sticked on in such way that the middle pad is firstly inserted in the interior of instep and middle sole sewel up each other to make middle pad corresponding to heel position locate on the middle sole there, then pill off the remained double surface adhesion belt on the middle pad and press it on the middle sole simultaneously so that the middle pad can simply adhere on the middle sole. This method can increase the wrokability and enhance the adhesive strength between the shoe middle pad and middle sole.

Description

technical field [0001] The present invention relates to a mid-pad of a shoe and a method of manufacturing the mid-sole of a shoe, which is provided with a detachable double-sided adhesive tape, which can be installed on the mid-sole of the shoe very simply. Background technique [0002] Now according to image 3 A general manufacturing process of shoes will be schematically described. First, in step (a), leather or artificial leather is sewn into the shoe upper (upper part) 11 . On the other hand, in the process (b), the midsole 13 is attached to the wooden form 12 by nailing, bonding, or the like. [0003] In step (c), the vamp 11 is covered on the wooden form 12, and the lower edge of the vamp 11 is sewn to the outer periphery of the midsole 13, that is, hanging. The bottom surface 11a of the shoe upper 11 can also be raised for good adhesion of the sole in subsequent processes. [0004] The subsequent process varies with the VP method and the CP method, and the CP meth...

Problems solved by technology

[0009] Therefore, after the process (f) is finished, at the stage where the midsole is surrounded by the upper, the surfaces of the midsole and the midpad that have been coated with the adhesive should be relatively matched to each other to install the midsole on the midsole. It is also a troublesome work for skilled operators, and the work efficiency is extremely low

[0010] Moreover, in the stage where the midsole is surrounded by the upper, the operation of applying the adhesive to the midsole must be thinner in order to make the adhesive coating evenly, which will lead to a decrease in the bonding strength of the mid-pad and the midsole. decline

[0011] After applying the adhesive on the center pad, it is necessary to wait for the adhesive to dry, and this time will also reduce the work efficiency

[0012] Moreover, while waiting for the adhesive to dry, the middle pads cannot be stacked for storage, so it is extremely uneconomical in terms of space.
