Abstract

The invention discloses a pair of leather shoes. Each leather shoe comprises a leather vamp and a sole, wherein the sole comprises an insole and an outsole; the leather vamp is inwards bent and is positioned between the insole and the outsole; the inward bending part of the leather vamp is bonded with the outsole. The leather shoes are characterized in that the inward bending part of each leather vamp comprises a cloth line and a leather line combined with the leather vamp into a whole, the bonding positions of the leather lines and the outsole are polished into a rough surface, and the leather lines and the cloth lines are connected and are jointly bonded with the outsoles. The invention also discloses equipment for polishing the leather lines of the leather shoes, and a leather shoe sewing method.

Description

technical field [0001] The invention relates to a leather shoe, in particular to the structure of the bonding part between the shoe upper and the outsole of the leather shoe. The invention also relates to a device for sanding the leather edges of said leather shoes. The invention also relates to a method for sewing leather shoes. Background technique [0002] In the traditional process, when the sole and the upper are bonded, the upper leaves a certain width edge, that is, the leather edge, which is used to bond with the outsole, but the wider the leather edge is, the more leather materials are used. The cost of leather is the highest in the material, so the leather edge takes up more cost of leather shoes, how to reduce the amount of leather material used in the leather edge has become an important issue for cost saving. Contents of the invention [0003] In view of the deficiency of the background technology, the technical problem to be solved by the present invention ...
