Problems solved by technology

[0012] 1. Unable to provide complete support for the foot
[0013] 2. Not suitable for use in shoes designed with arches
[0018] 1. High processing cost (due to the need for molds and hot molding equipment, and more materials)
[0019] 2. The hardness and weight increase, but the elasticity becomes worse

Embodiment Construction

[0047] see Figure 1 to Figure 8 , the method for making insole provided in a preferred embodiment of the present invention, its process description is as follows:

[0048] Such as figure 1 As shown, first prepare a sheet-like main body 31 made of PU foam material, a cloth layer 32 made of non-woven fabric and a mesh-shaped bottom layer 33 whose surface friction coefficient is larger than that of the main body 31 surface friction coefficient .

[0049] refer to figure 2 , attach the cloth layer 32 to the top surface of the main body 31 with an adhesive, and at the same time attach the bottom layer 33 to the bottom surface of the main body 31 , thereby forming a base material 30 .

[0050] refer to image 3 and Figure 4 , continue to carry out the forming operation on the base material 30, and use the chopping knife and the die base with a specific insole shape to stamp the base material 30 in advance, thereby obtaining a number of sheet bodies 40; because it is made by...

Abstract

The no-heating molded shoe insole making process includes preparing one sheet with top side and bottom side, and no-heating molding the sheet to form side walls, with at least part of the side walls being inwards inclined from the top side to the bottom side.

Description

technical field [0001] The present invention relates to insoles, in particular to a method for making an insole without heating and molding and its finished product. Background technique [0002] Currently commercially available insoles can be classified into flat insoles and molded insoles according to their structures. [0003] Among them, the flat insole is a sheet-like base material formed by foaming (note: the base material is made of polyurethane (Polyurethane-PU) or ethylene-vinyl acetate copolymer (Ethylene VinylAcetate-EVA)...etc. made) is placed between a shoe-shaped chopping knife and a mold base with the same shoe-shaped punching holes, and the substrate is obtained by chopping the base material from top to bottom with the chopping knife; since the physical properties of the base material itself have not been destroyed, therefore The foam structure of the side wall of the flat insole is complete and has good elasticity. When in use, it can provide good support a...
