A fly machine and sewing process
By using a fully automated, continuous sewing process for trouser fly machines, and integrating multi-functional modules, efficient and stable production of trouser flyes is achieved. This solves the problems of low efficiency and unstable quality in the traditional two-stage process, realizing high-quality and high-efficiency integrated production.

AI Technical Summary
The existing trouser fly sewing process is divided into two stages, resulting in low production efficiency and unstable quality, making it impossible to achieve high-quality, high-efficiency integrated production.
Design a trouser placket sewing machine that integrates a sewing machine head, a moving module, a fabric pressing module, a fabric turning module, and a clamping module to achieve continuous automated sewing of trouser plackets from cut pieces to final shape. The moving module drives the clamping module to perform two-dimensional precise movement. It integrates functional modules such as zipper fixing, placket positioning, folding assistance, and edge forming, eliminating multiple handling and repositioning of semi-finished products between processes.
It significantly improves production efficiency, ensures consistent product quality, reduces reliance on operator skills and labor intensity, shortens production cycles, and reduces time losses and quality risks caused by multiple handling and alignment.
