Features
  • Pays for itself in very little time due to decreased down time during roll changes.
  • No tools necessary.
  • Empty cores remove instantly.
  • Less chance of telescoping rolls when placing roll on arbor.
  • No parts to remove or lose.
  • Compensates for wide variation of core inside diameters automatically.
  • Eliminates possibility of core damage.
  • Drives equally in both directions (accelerating and decelerating)
  • Interchangeable with any arbor mounted type chuck.
  • Fully expanding periphery for maximum holding power.
  • Leaves are limited by "U" shaped restrainers in order to prevent over expansion (inflation without a core does not damage bladder)
  • Bladder is fully protected by leaves and restrainers whether inflated or deflated.
  • Return springs are provided to bring leaves back to minimum diameter when deflated.
  • Large bladder diameter produces maximum possible holding torque.
