DF–2000 Torque-Activated Shaftless Core Chucks
	Automatic torque activation – no side force needed. Rolling friction inside the chuck ensures tight core grip in low or high tension applications. Rolls can be run to the last wrap – no wasted web material. Concentric expansion minimizes roll bounce and vibration. Smooth jaws grip the core without damaging the core. Core chuck won't damage core ID's so cores can be reused. Step chuck accommodates different core sizes with no effort. Adapters and quick-disconnect core chucks also available for multiple core sizes. "Core Kicker" models automatically eject cores from chuck.

LC-1000 Latching Roller Core Chucks
	Perfect for form, fill, and seal packaging, window patching envelopes, as well as tag, tape, and label production. Easy roll changes in no time....without tools.
