With the development of heating machine industry, es into the decreasing time, with some big problems appearing behind their backs, such as unreasonable industrial construction, labor intensive product concentrates on industry, something technical far behind with developed countries, high energy consumption, serious environment pollution which gives rise to the lack of natural resources, small panies, low creativity and management level. During this, technical creativity is extremely low which needs tobe paid more attention, in order to change this, creative design has to play a more indispensable role. This paper is about heat setting machine design, which consists of driving force section , driving gear, stretching and heat-setting device. Driving force section selects the torque as much as we can get to meet delivery and at the same time, the rotated speed of the motor that we choose depends on string ’s size and material. Driving gear is made upof motor, coupling, reducer, roller and the ponents. The driving route :1 motor -2 Coupling -3 reducer -4 Spindle -5 chain d
