Description

Technical Field

[0001] This invention patent is an invention patent with application number (2025115373667), filed on October 18, 2025, entitled (Method for making right-angled high-sleeve outer seam of upper shoe) (divisional application). This invention patent relates to a shoe, and more specifically, to an upper shoe with right-angled high-sleeve outer seam. Background Technology

[0002] There is little innovation in the sole structure and processing technology of stitched shoes. Stitched shoes first sew the welt and upper parts together, and then sew the outsole and welt together through adhesive stitching. The stitching process is complicated and greatly affects the production efficiency. Summary of the Invention

[0003] To overcome the problems existing in the prior art, this invention patent provides a right-angled high-sleeve outer seam for upper-stitched shoes, changing the manufacturing structure of upper-stitched shoes, simplifying the process, and greatly improving production efficiency. To achieve the above objective, this invention patent provides a preferred method for the right-angled high-sleeve outer seam for upper-stitched shoes, wherein the narrow side of the right-angled high-sleeve and the upper perimeter of the outsole are bonded and fixed with adhesive, and the upper edge of the wide side of the right-angled high-sleeve and the lower perimeter of the upper are sewn together with thread.

[0004] Preferably, the underside of the large sole and the thin sole are bonded and fixed together with adhesive, and the narrow side of the right-angled high welt strip is bonded and fixed together with the outer perimeter of the large sole and the thin sole with thread.

[0005] Preferably, the half-steel plate and the upper arch of the outsole are bonded and fixed together with adhesive.

[0006] Preferably, the thin bottom side and the anti-slip bottom are bonded and fixed together with an adhesive.

[0007] Preferably, one side of the welt and the surrounding area of ​​the shoe upper are sewn together and fixed, and the other side of the welt and the upper edge of the right-angled high welt on the sole are sewn together and fixed.

[0008] Preferably, the outer seam of the right-angled high-top welt on the upper shoe is connected and processed in the following steps during production: the narrow side of the right-angled high-top welt is bonded and fixed to the upper perimeter of the outsole with adhesive; the upper edge of the wide side of the right-angled high-top welt is sewn and fixed to the lower perimeter of the upper with thread; the lower side of the outsole and the thin sole are bonded and fixed with adhesive; the narrow side of the right-angled high-top welt is sewn and fixed to the outer perimeter of the outsole and the thin sole with thread. Sewing the thin sole prevents the direct bonding between the outsole and the anti-slip sole from coming unglued; the half-steel plate is bonded and fixed to the arch support of the upper with adhesive; the half-steel plate is the same width as the outsole, so it will not collapse or deform, protecting the arch; the lower side of the thin sole is bonded and fixed to the anti-slip sole with adhesive; one side of the welt is sewn and fixed to the perimeter of the upper with thread; the other side of the welt is sewn and fixed to the upper perimeter of the wide side of the right-angled high-top welt on the sole with thread. This sewing method prevents water from entering the welt.

[0009] The beneficial effects of this invention patent are: a right-angled high-waisted outer seam structure for upper-stitched shoes, which changes the structure of upper-stitched shoes, makes the process less complicated, and greatly improves production efficiency. Attached Figure Description
