PU/TU Turret Unwinders
These unwinders are based on a turret design concept and center unwinding capability. It is featured with an automatic web splicing system and requires very simple operation. Two pneumatic expandable shafts (1 active, 1 waiting) are powered by individual flat DC or servo drive motors. Unwinding speed is controlled by a PLC that processes information such as dancer roll position and main processing machine speed, to automatically set rotation speed of shafts. A two-
The body of PU turret unwinder can be manually shifted in cross direction to easily adjust the reel axial position relative to the main processing machine. We also supply pneumatic film accumulators for inline operation with other processes.
