Most of the industrial sewing machines are general-purpose sewing machines, including lockstitch sewing machines, chain stitching machines, overlock sewing machines and interlock sewing machines, etc., and the use rate of lockstitch sewing machines is the highest
A general sewing machine consists of four parts: machine head, machine base, transmission and accessories.
The machine head is the main part of the sewing machine. It consists of four mechanisms of barbed material, thread hook, thread take-up, and material feeding, and auxiliary mechanisms such as winding, pressing, and falling teeth.
The machine base is divided into two forms: platen and chassis. The platen of the platen type machine base plays the role of supporting the machine head, and is used as a workbench during sewing operations. There are many styles of table tops, such as folding Tibetan type with one bucket or multiple buckets, cabinet type, desk type and so on. The case of the case-type machine base plays a role in supporting and storing the machine head, making the sewing machine easy to carry and store.
