Abstract

A method for making a shoe in a three dimensional manner includes: a step of sewing and weaving, a step of prototyping, a step of inserting an insole, a step of seaming, a step of inserting a shoe tree, a step of pressing which includes: preparing a sole mold filled with a semi-cured sole, and a decorative-member mold filled with a semi-cured decorative member, pushing the decorative-member mold 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 cloth sleeve to melt the semi-cured sole and decorative members; the decorative members and the sole will be fully cured.

Claims (12)

1. A method for making a shoe in a three dimensional manner, comprising:

a step of sewing including: sewing a net cloth into a cloth sleeve, wherein the cloth sleeve has an open end, a closed end, and an annular connecting portion between the open end and the closed end, defining a portion between the annular connecting portion and the closed end as an inner layer, and defining a portion between the annular connecting portion and the open end as an outer layer;

a step of prototyping including: folding and tucking the inner layer from the annular connecting portion into the outer layer to make the inner and outer layers overlapped, so that the annular connecting portion forms a shoe opening, and the inner layer defines an inner space;

a step of inserting an insole including: inserting the insole between the inner layer and the outer layer;

a step of seaming including: seaming the open end to seal the insole between the inner and outer layers;

a step of inserting a shoe tree including: inserting the shoe tree into the inner space to prop open the inner and outer layers in the shape of the shoe tree;

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 first abutting surface is abutted against the cloth sleeve, the decorative-member mould includes a decorative-member mould cavity and a second abutting surface, the second abutting surface is abutted against the cloth sleeve, filling the sole mould cavity with a semi-cured sole, filling the decorative-member mould cavity with a semi-cured decorative member, pushing the decorative-member mould and the sole mould against the outer layer to attach the semi-cured decorative member and the semi-cured sole to the bottom surface to the outer layer; and

a step of heating including: heating the cloth sleeve to melt the semi-cured sole and decorative member, the decorative member and the sole inside the sole mould are melt and cured when heated, when the cloth sleeve cools off, the inner and outer layers are solidified into the shape of the shoe tree.

2. The method as claimed in claim 1 , wherein the net cloth is made of a material selected from a group consisting of hot melt yarn, hot melt filament, thermoplastic polyurethane and polyurethane particles.

3. 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 polyurethane and polyurethane.

4. The method as claimed in claim 1 , wherein the semi-cured decorative member and the semi-cured sole are melted when heated to 30-80° C.

5. 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.
