Embodiment Construction

[0026] The invention provides a method for processing shoe uppers and general shoes, in which the multi-layered composite sheets are heated and activated to be stretchable and then put into a mold. The mold is used to press the composite sheet into the desired three-dimensional shape to form the composite upper. The formed upper can be attached to the sole together with other components to produce a shoe. The processing method of the invention simplifies the structure of the shoe, reduces the processing cost, and makes the processing of the shoe upper more flexible, so that the shoe has various characteristics.

[0027] figure 1 The flowchart of shows generally a kind of method of processing shoe upper of the present invention. Wherein in step 10, two or more layers of materials are used to form a substantially planar composite sheet; in step 12, the substantially planar sheet is heated and activated to be extensible; in step 14, once the planar composite sheet is substantia...

Abstract

A method of manufacturing a multi-layer, composite footwear upper having a three-dimensional geometry includes the steps of forming a substantially planar composite sheet from two or more layers, heating the composite sheet, and compression molding the composite sheet into the three-dimensional geometry of the footwear upper. The composite sheet is formed by laminating a first layer of thermoplastic foam to a second layer of thermoplastic urethane (TPU), preferably in the form of a TPU film. A third layer of mesh fabric can be interposed between the first and second layers. The composite sheet is compressed after heating in a mold cavity to achieve the desired three-dimensional geometry. The composite sheet can be compression molded into separate sections which are assembled after molding to form the footwear upper. Alternatively, the composite sheet can be compression molded into a seamless, unitary footwear upper that requires minimal, if any, assembly for completion. The multi-layer composite upper can be applied to a sole to form performance footwear suitable for use in a wide range of conditions.

Description

Background technique [0001] Many outdoor sports require specialized shoes designed for use in extreme conditions. Specialized footwear such as hiking boots, skates, ski boots, hiking boots, etc. provide the wearer with protection from extreme temperatures, humidity, and damage to the feet from difficult terrain. In order to provide this type of protection, special shoes are usually made of a material or a combination of materials that are insulating, moisture-resistant, and wear-resistant. [0002] Production of specialty shoes is labor and cost intensive and requires complex and expensive molding and sewing equipment. For example, the production of special shoes with leather requires manual cutting and sewing of leather. Equally, expensive and complicated high-pressure injection equipment and moulds must also be used to produce special-purpose shoes with plastic raw materials. [0003] In addition, the production of specialty shoes often requires multiple layers of materia...
