This machine processing and assembly is superior, shape is beautiful and structure is reasonable. The whole machine can run smoothly with low noise. It is easy to adjust zipper. Bag hole can be punched accurately. The speed is fast. The machine adopts PLC three servo traction control, temperature centralized control, reducing electricity consume. The feeding system adopts constant tension control, and ensures the smoothness of the material and the accuracy of the control. Middle tension floating roller adopts dynamic compensation mode, to make the process of pulling material fluctuates slightly. Tension control is stably. The creasing overlaps and stability of horizontal and arc heating knife are good.
