	Concentric expansion minimizes roll bounce and vibration. Automatic torque activation – no side force needed. Smooth jaws grip the core without damaging the core. Rolls can be run to the last wrap – no wasted web material. Core chucks don"t damage core ID's so cores can be reused. Rolling friction inside the chuck ensures tight core grip in low or high tension applications. Step chuck accommodates different core sizes with no effort. Core chuck adapters and quick-disconnect core chucks also available for multiple core sizes. "Core Kicker" models automatically eject cores from chuck.
