The sewing performances of an industrial sewing machine under high speed working condition were impacted severely by vibration, noise and wear because of joint clearance. A plane-notch flexure hinge replacing a traditional rigid joint was researched to improve sewing performances of a machine. Forms and characteristics of those existing flexure hinges were ana-lyzed. Those parameters, such as the trajectory of feeding teeth and reaction forces at different supporting points of GC6720 type high speed industrial sewing machine, were simulated consi-dering a plane-notch flexure hinge and a traditional rigid joint respectively. A plane-notch flexure hinge was designed and fixed with the feeding mechanism. The testing experiments of the sewing machine including a plane-notch flexure hinge and a rigid joint respectively were finished. A con-clusion could be drawn that a flexure hinge can improve sewing performances of an industrial sewing machine.
