After the roll of material (or empty core when rewinding) is placed on the chuck, a slight rotation locks the core in place without the need for air, keys, or special tools. The chuck continually grips the core in response to the torque being transmitted – more torque means higher grip force. A simple turn of the roll in the non-web direction unlatches the chuck for easy removal of the core (or completed roll when rewinding).

The patented design of the chuck's central hex features detents, or small grooves, which cause the latching action, and ensure concentric expansion. Rolls don’t bounce, making it easier to control web tension and quality.

The LC–1000 does not depend on a bladder to force the gripping elements to grip the core. Bladders are often maintenance intensive, and don’t have the ability to provide true concentric expansion.

Because the chuck has a minimal number of moving parts, the LC-1000 latching core chuck requires very little, if any, maintenance.

The durable urethane rollers provide non-slip engagement of any core material without causing core damage.

Unlike the knock-in cones or wedges that the LC–1000 often replaces, this chuck is virtually impossible to get stuck in a core.

Roll changes are much faster with this core chuck. A simple turn removes the roll with the LC–1000. With cones, at least one has to be physically removed to unload the roll, wasting valuable time.

Narrrow web converting and packaging processes benefit most from the LC-1000 core chuck.
