Abstract: Industrial sewing machine is made up of four mechanisms, the take-up mechanism, the needle piercing mechanism, the fabric feeding mechanism and the bobbing mechanism. Sewing is a complicated process involving synchronised motion of the four parts. The performance of the sewing machine is determined by the quality of mechanical design and cooperation of the four mechanisms. Each mechanism can be made by different kinds of forms. Considering the requirement of high-speed sewing, the best mechanical structure is chosen for each mechanism. After the whole design, simulation software RecurDyn® is used to simulate the machine and diagnose the synchronisation of the four mechanisms.

Keywords: five-bar linkage mechanisms; high-speed sewing; kinematics simulation; sewing machines; mechanical design.
