Technical Field

The invention has the following patents: relates to a manual upper thread shoe, in particular to a method for manufacturing an outward turned welt sewn on the upper surface of the upper thread shoe.

Background

With the development of market economy; the living standard is improved, people wear the shoes more and more personalized, the line-threading shoes are less innovative in the aspects of sole structures and processing techniques for a long time, the line-threading shoes are sewn along the edges, and two manufacturing methods exist in the current manufacturing technique.

One is manual welt sewing, which requires an artist to be exquisite manually, and the quality problem occurs when the welt and the insole are too thin and uneven to reach a certain thickness.

The other is a Goodyear machine sewing welt which requires that the welt has a certain thickness and can be cut off by a machine.

Disclosure of Invention

In order to overcome the problems in the prior art, the invention discloses: the method for manufacturing the outward turned welt sewn on the upper surface of the upper line changes the method for connecting the welt of the upper line, and even if the welt is too thin, the quality problems of uneven welt seam and machine cutting can not occur.

The invention has the following patents: the technical scheme includes that the upper side of the upper is sewn at the thin side edge and the middle bottom edge of the welt, the welt is sewn with a circle of the outer side of the upper, a pressing stubble is reserved at the butt joint of the welt, the upper is split into a shoe last, the shoe last is glued and shaped, the welt is turned outwards after the shaping, the welt which is not turned upwards is too wide, the welt and the upper are glued together by using glue, the turning-outwards welt and the bottom opening are horizontal, and the turning-outwards welt is glued with the large bottom stitching.

The beneficial effects of the invention are: a method for manufacturing an outward-turned welt for sewing a top-stitching upper surface changes a method for connecting the welt of a top-stitching shoe and sewing the outer side of the upper along the welt, is simple and easy to operate, and can not cause quality problems due to uneven sewing even if the welt is too thin.

Detailed Description

With reference to fig. 1, as follows: method for manufacturing outward turned welt sewn on upper surface of upper thread shoe

Comprises a welt 1 and an upper 2 which are sewed 3

The method is characterized in that: the upper side of the upper 2 at the edge of the thin side of the welt 1 and the edge of the middle sole edge is sewn with 3, the welt 1 is sewn with the outer side of the upper 2 for a circle, the butt joint part of the welt 1 is left with stubble, the upper 2 is broken into lasts, glued and shaped, the welt 1 is turned outwards after shaping, if the welt 1 is too wide, the welt 1 which is not turned upwards and the upper 2 are glued together by using glue, the turning-outwards welt 1 and the sole opening are horizontal, and the turning-outwards welt 1 is glued with the seam of the large sole.
