WO2007065367A1 - Method of manufacture of a removable insole - Google Patents

Abstract

Method of manufacture of a removable insole, in which a surface material is stuck on a shaped non-thermoplastic interlayer, which is stuck on a thermoplastic bottom material, and the brim of the surface material is clung to the thermoplastic bottom material immediately. All materials are shaped into removable insole by mold according to the shape of the removable insole. The brim of the removable insole is the immediate stickup part of the thermoplastic bottom material and the surface material, and the non-thermoplastic interlayer is covered with the thermoplastic bottom material and the surface material.

Description

 Manufacturing method

 This refers to the manufacturing method in the field of processing technology. Background wood

 It is freely exchangeable and meets the requirements of rest and workers.

 It extends along the curvature of the sole of the foot to the vertical of the foot

 The function is not at home but also for cleaning.

 Generally, most plastic materials are processed, such as EVA PP. Plastic materials are often high due to insufficient physical properties due to their physical properties. Content

 The purpose of this book is to solve the shortcomings in the existing wood.

 Method of production. Methods Plastic and non-plastic materials are mixed and processed into shapes. The physical properties of plastic and non-plastic materials are sufficient to overcome the defects.

 The manufacturing method described herein includes the following steps and

 The first step is above the plastic material in the formed non-plastic material and above the non-plastic material at the outer edge of the non-plastic material

 Plasticity Direct

 Second, shape the upper material through the mold

The direct part of plasticity is in the non-plastic material.

 This mold includes the lower mold part and the direct plastic part of the upper and lower molds to make it plastic. Plasticity includes moldable vinyl acetate copolymer EVA and polyvinyl chloride.

 VC or ethylene PE non-plastic materials include molded, or (P includes or leather.

This Generally, non-plastic materials, that is, materials whose finished products are heated and still shaped, have a lot of defects in processing, such as not easy to reshape, high shrinkage, surface wear resistance, and high processing cost. The ingenious use of non-plastic materials in plastic materials not only overcomes the processing cost of non-plastic materials but also greatly reduces the low special characteristics of non-plastic materials to solve the high rate of simple plastic materials.

 Compared with the existing wood, the present wood has the following and beneficial effects

 1. The plastic and non-plastic materials are mixed and processed

2. Due to the non-plastic materials, the soft, elastic, elastic, etc.

 3. The large-scale merger that could have been made must be made by hand. 1 is the material in this manual

 2 is made by this

 3 is a schematic diagram of the mold and parts in this specification. Hugh way

 The following group and this step. EVA, VC or EVA on the upper plastic. PE can completely replace non-plastic materials, and sponges or sponges can completely replace each other. The effect is still very good.

 1

 Step 1 As shown in 1 above the plastic non-plastic material tungsten above the plastic EVA 2 above the non-plastic material sponge 2

3 in non-plastic material sponge 2 outer edge of plastic EVA directly

 I.e. the part shown in 4

Second, the upper material is formed through the mold according to the shape. The direct part of the edge plastic EVA 3 4 of the non-plastic material tungsten is 2 of them.

 As shown in 2 and 3, the mold includes two parts: upper mold 5 and lower mold 6. The mold is at the heel. Upper mold 5 and lower mold 6 are vertical. Direct plastic EVA

 The direct part of 3 4 is made of plastic to solve the problem caused by the height drop.

 2

 Step 1 In the non-plastic material formed above the plastic VC 2 In the non-plastic material 2 Above the 3 3 At the outer edge of the non-plastic material 2 The plastic VC is connected to the part shown in 4

 Second, the material will follow the shape: mold,. , Forming, making edge plastic VC 3 direct part 4 non-plastic material 2 is in it.

 3

 The first step is above the plastic E 1 in the molded non-plastic material sponge 2 in the non-plastic material sponge 2 3 leather 3 in the non-plastic material sponge 2 the outer edge of the plastic P is directly the part shown in 4

 Second, shape the upper material through the mold

The edge of the plastic PE leather 3 is the direct part 4 of the non-plastic material sponge 2 is in it.

 The above can be better.

Claims

 Requirement 1.
