Description

[Detailed Description of the Invention] This invention was developed with the aim of increasing the efficiency of pasting operations and obtaining high-quality products.

The drawings show an example of the apparatus used in carrying out the invention,
l is the support rod, and jl above the support rod l! A lVc pressure receiving plate is provided, and a pressing plate 3 is provided directly above the pressure receiving plate 4 and is movable vertically in close proximity to the pressure receiving plate JJC, and the pressure receiving plate is wrapped on the pressure receiving plate side of the bottom crimping device. After 5K, I set up a rubber bag.
The rubber bag 4A has a shape that approximates the shoe body sI/c when inflated, and has a lower end Kg! A sealing device 7 is provided to close the gap between the air inlet 6 and the support rod 1 that protrudes beyond the rubber bag.

Then, a solvent-activated urethane adhesive α was applied with a doctor knife and dried, and the fabric was shaped to resemble the shoe itself! I! Process the lining fabric t to obtain a lining fabric t, fit the lining fabric t into a rubber bag and install it in the device, and insert the lining fabric 1K insole 9.
The lining fabric T and the insole 9 are adhered to each other with urethane adhesive α, and the same urethane adhesive α is applied to the surface of the insole D, while the shoe body is bonded with the solvent of the adhesive α described in jIcIIr. After pouring a certain amount of methyl ethyl ketone and allowing the methyl ethyl ketone to sufficiently adhere to the inner surface of the shoe body S, the shoe body S is quickly fitted into the lining fabric T, the pressure plate 3 is lowered, and the pressure plate 3 and the pressure receiving plate are pressed together. Hold the sole side of the shoe and glue the shoe body 5, the midsole and the lining fabric R to each other, and then inject 9 Qi from the injection port 6 to inflate the rubber bag. The lining fabric L is brought into pressure contact with the inner surface of the shoe body S by the expansion pressure of q, and the creases are brought into contact with the inner surface from 1 to 12 minutes.
After holding the rubber bag for 0 seconds, the product is removed from the equipment after removing the rubber bag, and an elliptical reinforcing tape sB is attached to the shoe opening to complete the product.

In addition, the rubber bag used in the experiment was 9 atm pressure/cd.
I used a soft bag that can expand to almost double its size, but it is fine as long as it is moderately soft.Also, you can use a synthetic resin bag instead of a rubber bag without any problem.

The material for the lining cloth t is made of suffumelite, but of course it does not have to be made of suffumel, and the amount of adhesive α applied to this lining cloth tVc is appropriate to be #-t coop7-・mt/! ; If it is less than 01/ylsst, the adhesive force will decrease and sA;ol! /let or more, the adhesive a tends to make the entire product too hard; however, it seems that the amount of application should be determined depending on the type of adhesive.

In addition, there is also a method of attaching the backing cloth fK adhesive after obtaining the backing cloth t processed by IIi.

Depending on the pressure of the injected air, an outer star can be placed around the shoe body to prevent the shoe body from inflating too much due to air pressure.

Since the present invention has the above-mentioned configuration, it is possible to reliably bond the lining fabric of the body part and the shoe body 5 without any trouble, which has been considered difficult up to now. The various defects of conventional products caused by "floating" can be universally eliminated and high-quality products can be provided.
