Method for fixing a decorative member on a vamp of a shoe in a three dimensional manner

Abstract

A method for fixing a decorative member on a vamp of a shoe in a three dimensional manner includes: a step of pressing which includes: preparing a sole mould filled with a semi-cured sole, and a decorative-member mould filled with a semi-cured decorative member, pushing the decorative-member mould against the vamp with the semi-cured decorative members and the semi-cured sole pressed against the bottom surface; and a step of heating which includes: heating the shoe to melt the semi-cured sole and decorative members; the decorative members and the sole will be fully cured.

What is claimed is: 
     
         1 . A method for fixing a decorative member on a vamp of a shoe in a three dimensional manner, the vamp including an upper surface, a lateral surface and a bottom surface, the method comprising:
 a step of pressing including: preparing a sole mould and a decorative-member mould, wherein the sole mould includes a sole mould cavity and a first abutting surface, the decorative-member mould includes a decorative-member mould cavity and a second abutting surface, filling the sole mould with a semi-cured sole, filling the decorative-member mould with a semi-cured decorative member, pushing the decorative-member mould against the upper surface or the lateral surface of the vamp, with the second abutting surface pressing against the upper surface or the lateral surface to attach the semi-cured decorative members to the upper surface or the lateral surface; pushing the sole mould against the bottom surface with the first abutting surface pressing against the bottom surface to attach the semi-cured sole to the bottom surface; and   a step of heating including: heating the vamp to melt the semi-cured sole and decorative members; the decorative members and the sole are cured when heated to a predetermined temperature.   
     
     
         2 . The method as claimed in  claim 1 , wherein the semi-cured sole and the decorative member are made of a material selected from a group consisting of rigid polyurethane, casting and polyurethane. 
     
     
         3 . The method as claimed in  claim 1 , wherein the sole mould and the decorative-member mould are made of a material selected from a group consisting of polyurethane, thermoplastic polyurethane and silicon. 
     
     
         4 . The method as claimed in  claim 1 , wherein the sole mould and the decorative-member mould are soft or rigid moulds. 
     
     
         5 . The method as claimed in  claim 1 , wherein in the step of heating, the semi-cured sole and decorative members are heated to 30-80° C. when they are heated to a melted state. 
     
     
         6 . The method as claimed in  claim 1 , wherein the predetermined temperature is 60-120° C.
