ABSTRACT:
A take-up unit for winding strand material comprising a strand-tensioning device having a compensator arm and a compensator wheel at a free end thereof for carrying a strand material to be wound and an air cylinder having means for receiving air under pressure is described. The air cylinder is interconnected with the compensator arm, thereby compensating for a change in tension of the strand material being wound. A plurality of strand-tensioning devices are interconnected with a common air supply, permitting the adjustment of the tension in the plurality of strand-tensioning devices by regulating the air feed from the common supply.
