Special template for sewing waistband

Abstract

The invention belongs to the technical field of dress making, and particularly relates to a special template for sewing a waistband. The waistband is provided with a waist surface and a waist lining; the template is provided with a lower template for fixing the waist surface; the lower template is articulated with an upper template for fixing the waist lining; the outer side of the upper template has a stitching straight flange; and the length of the upper and lower templates is greater than or equal to the length of the waistband. By adopting the special template for sewing a waistband, the shortcomings of skew, wrinkles, inconsistent surface-lining tightness and space and the like of the sewn waistband are avoided, the product quality is improved, the product quality is stabilized, and the repair rate is reduced; and meanwhile, the requirements for the skills of sewing workers are greatly reduced, and the sewing efficiency is greatly improved by reasonably matching the template process with the production line.

AI Technical Summary

Benefits of technology

This patented technology allows for better control over how well-sealed welding processes occur during wafer manufacturing by providing templates made up from specific materials or layers attached onto certain parts of an already completed package. These templates help prevent any issues like uneven pressure distribution caused when pressing downward force instead hitting them directly without causing damage. By doing these techniques, we improve the overall performance and reliability of semiconductor devices produced through packaging technologies.

Problems solved by technology

There are two main types of methods commonly employed during fabrication: welding and thread stitching techniques that require precise positional alignations beforehand. However these processes can result in imperfections like cracks, uneven thicknesses, bumps/walls caused by misaligned threads, lack of consistency across different materials (such as rubber), difficulty in adjusting dimensions due to warping, excessive pressure from pushing downward force against the material being worked upon, and other issues related to current methods.
