Inclined cutting and cutting-through method based on hollow kidney-type sandal innersole

Abstract

The invention discloses an inclined cutting and cutting-through method based on a hollow kidney-type sandal innersole. The method includes the steps that the innersole is cut, so that the width of the innersole is equal to that of an outsole, and the innersole is grinded through a grinding machine; the innersole with the grinded bottom face is placed on a working table with the bottom face facing upwards, and lasting position lines are marked according to a shoe last template; the included angle of 30-35 degrees is formed between the cutting edge of a cutting knife and the plane of the innersole, cut pieces are obtained through cutting in an inclined mode along the marked lines, and the slope width of the cut pieces is 4-5 mm and is just the slope stubble width of the innersole of a seam shoe; the interior becomes the innersole of the seam shoe, and external narrow strips serve as welts; when an upper and the innersole are combined, the innersole and the outsole are sewn or glued; the angle of the cutting edge is controlled, and cutting is finished through one-time cutting feed; line containing grooves are milled in the flesh face of the innersole through milling cutters. The innersole and the outsole are reasonably fixed, and line inclined cutting cut pieces are machined on the innersole, so that the junction positions of the innersole and upper and welt covering parts are equal in height, arris protrusions on the innersole are flush with one another, and seam allowance lines are sealed tightly.

Description

technical field [0001] The invention relates to a method, in particular to a method based on obliquely cutting the insole of hollow-waist sandals. Background technique [0002] Shoes are things made of leather, cloth, wood, grass, plastic silk, etc. that are worn on the feet and land on the ground when walking. Shoes have a long history of development. About 5,000 years ago in the Yangshao culture period, the most primitive shoes made of animal skins appeared. Shoes are a tool for people to protect their feet from injury. The earliest people invented fur shoes in order to overcome special circumstances and prevent their feet from being uncomfortable or injured. Shoes have developed to the present, and they have formed what they are now. Shoes of various styles and functions can be seen everywhere. In traditional Chinese wedding customs, shoes are a kind of mascot, which is a symbolic folk custom produced by the pairing of shoes and the homonym of "shoe" and "kai". Some ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned existing empty-waist sandals, because the upper is sandwiched between the outer bottom and the inner bottom, so that there is a level difference at the junction of the exposed inner bottom and the upper covered part, resulting in the inner bottom. In order to solve the problems of unevenness and tight fit of the slit line, a method of obliquely cutting the inner sole of hollow-waist sandals is designed. This method reasonably fixes the inner sole and outer sole, and The processing line is obliquely cut and sectioned, so that the junction of the inner sole and the upper covering part is of the same height, the corrugation of the inner sole is flat and the slit line is tightly sealed, which solves the problem that the existing hollow-waist sandals are caught by the upper. Between the bottom and the inner bottom, there is a level difference at the junction of the exposed inner bottom and the side covered part, which leads to the unevenness of the inner bottom and the poor sealing of the slit line
