Leather shoe upper processing and molding method

Abstract

According to the technical scheme, the invention provides a leather shoe upper processing and molding method. The method comprises the following steps: a, making a reference plate body, which is samewith an upper leather side, by virtue of a hard plate body; b, using leather leftover materials obtained from cutting; c, splicing and sewing the leather leftover materials in the reference plate body; d, hot-ironing sewed parts of the upper leather side which is sewed in the step c; e, brushing glue to the upper leather side in the step d and sticking lining cloth; f, heating and softening the upper leather side which is stuck with the lining cloth; g, bushing the softened upper leather side in a shoe last and implementing lasting; h, trimming the lasted upper leather side; i, molding the upper which is trimmed in the step h; j, implementing cold-molding on the upper which is obtained from hot-molding in the step i; and k, sewing the cooled upper with a sole. According to the technical scheme, the leather shoe upper processing and molding method, which can save production cost, protect environment and avoid harm, is provided.

Description

technical field [0001] The invention relates to the field of leather shoe production, in particular to a method for processing and shaping the upper of leather shoes. Background technique [0002] When making leather shoes, the upper needs to be processed, and then the upper and the matching sole are stitched or bonded to form a finished product. [0003] The processing and shaping of the upper is the key to ensure the beauty and quality of leather shoes. The traditional shoe upper processing steps mainly include: a. Select leather material; b. Cut the selected leather material into a specific size shoe upper leather surface; Fitting the interlining; d, heating the upper leather with the interlining to soften it; e, putting the softened upper leather into the shoe last for stretching; f, stretching the lasted shoe upper Trimming the surface so that its edges are flat and fully fit the shoe tree; g, bonding the leather surface of the shoe upper in step f to the sole, and th...

Problems solved by technology

[0004] In the above-mentioned processing technology, more scraps will be produced during cutting, and the scraps are usually not properly utilized, resulting in a waste of resources, and the production cost cannot be reduced; and when the upper and the sole are bonded, the glue contains More harmful substances have certain harm to the wearer's body

Moreover, during the molding process, the top of the upper is heated at the same temperature as the side, which makes the top prone to deformation
