Differential Shaft is a sophisticated winding shaft for slitter rewinder machine, used as duplex shaft winder (center winding type).

  • It is capable of compensating speed variation due to gauge variation with multi cores.
  • Minimum 20 mm core width is possible.
  • Reel holding is possible at any position across the width.
  • No–;time lost in re–positioning cores since no distance pieces are required.
  • Shaft can run at very high speed.

This shaft consists of slotted shaft, rubber bladders, hard and ground steel cage with ball type gripper. Teflon® strip for better slippage and self lubricating segments separating two adjacent steel cages.
