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.
