reading to realize humanized operation. 2. The whole machine is controlled by Panasonic AC servo system, and the  winding tension is controlled by Japanese precision low friction cylinder,  which can improve the precision and compensate the tension when the  speed is lowered. 3. It has the function of secondary heat seal. The time and pressure of  primary heat seal and secondary heat seal can be set separately, which is  convenient for the later process. 4. The frame of the machine is of integral structure, which can effffectively  improve the accuracy and durability and greatly reduce the mechanical  vibration by changing the lack of strength of multi-piece assembly. 5. The main reel seat of the machine adopts an integral tunneling  structure, which avoids the loss of precision and the deviation of concentricity caused by multi-chip connection, and greatly improves the accuracy and stability after long-term use.
