Problems solved by technology

[0002] The current upper processing of leather shoes is generally to cut the leather into a plane first, and then stitch and sew the side or heel to form a complete upper. This upper forming method will leave a longitudinal seam on the side or heel of the upper. It is easy to affect the flatness of the edge of the shoe opening and the fit between the sole and the upper, and reduce the grade of leather shoes

Embodiment Construction

[0015] The present invention will be described in further detail below in combination with specific embodiments.

[0016] Firstly, design and manufacture the last corresponding to the shoe type that needs to be processed and manufactured, select soft cowhide, and cut it into an appropriate size.

[0017] Put the cowhide cut to an appropriate size on the last. First, select a few fixed points at the bottom of the last, and fix the cowhide on the last to ensure that the skin will not shift during processing; The pleats are stretched and the leather is fixed on the bottom of the last, and the corresponding upper area is baked and heated to shrink the leather surface until it is fixed and baked for one week, and the entire leather surface is tightly stretched on the last.

[0018] Then draw the shape of the shoe opening on the cowhide stretched on the last and cut it.

[0019] Remove the leather from the last, lay the leather flat, sew the inside, sew the edge of the shoelace ho...

Abstract

The invention discloses a seamless forming method of uppers of leather shoes. The seamless forming method comprises the following steps of step 1, wrapping leather fabric on shoe lasts, folding edges of the leather fabric into uniform folds and fixing at the bottoms of the shoe lasts one by one and performing baking and heating in corresponding upper areas to enable leather surfaces to shrink to level off every time a fold is fixed until a circle of the leather fabric is fixed and the baking is achieved; step 2, designing and cutting out shapes of top lines on the leather fabric machined through the step 1; step 3, removing the leather fabric from the shoe lasts, performing further fine machining and sewing linings; step 4, covering machined products in the step 3 on the shoe lasts once again and fixing at the bottoms of the shoe lasts one by one and performing the baking and heating to enable the leather surfaces to level off once again according to fold marks formed in the step 1; and step 5, removing machined products in the step 4 from the shoe lasts and trimming redundant fabric of bottom edges. The seamless forming method of the uppers of the leather shoes has the advantages of employing a leather heating and sizing way to perform machining on the uppers, avoiding longitudinal seams on the uppers, improving the flatness of tape edges of the top lines and the joint degree of the uppers and soles and improving the grade of the leather shoes.

Description

technical field [0001] The invention relates to a process for processing leather shoes. Background technique [0002] At present, the upper processing of leather shoes is generally to first cut the leather into a plane, and then splice and sew the side or heel to form a complete upper. This upper forming method will leave a longitudinal seam on the side or heel of the upper. It is easy to affect the flatness of the edge of the shoe mouth and the fit between the sole and the upper, and reduce the grade of leather shoes. Contents of the invention [0003] In view of the above-mentioned technical defects, the present invention provides a method for processing the upper of leather shoes without splicing and sewing and without longitudinal seams: [0004] A method for seamlessly forming leather shoe uppers, comprising the following steps: [0005] 1. Wrap the right-sized leather fabric on the last, fold the edges of the fabric into even folds, and fix them one by one on the b...
