The Composite Machine adopts automatic motor tension control system (swing roller, encoder). Variable frequency motor is used for main machine winding, gluing and oven motor. The two working positions of winding and unwinding adopt automatic cutting and material receiving, and the two unwinding automatic rectifying device.

　　The compound roll of Composite Machine mainly includes hot pressed steel roll, hot pressed rubber roll and cooling roll. Its functions are as follows

　　1. Hot pressed steel rod: the laminating machine adopts resistance wire heating or mold temperature oil heating. Its main function is to activate the glue film molecules after the glue film comes out of the oven, so as to obtain higher adhesive force. Generally, the composite temperature is set at 50 ~ 80 ℃. Adopt mold temperature, oil heating temperature is even, more guarantee for product quality.

　　2. Hot press cot: its function is to make the cylinder get pressure and contact with the hot press steel roll through the high pressure source. The cot should be resistant to organic solvent, and its hardness is about 80 ~ 85.

　　3. Cooling roller: to cool and shape the film after lamination, eliminate the internal stress of the film, and obtain higher initial viscosity and composite peeling strength of the glue.
