LC-1000 Latching Roller Chuck

A slight rotation locks the core in place without the need for air, keys, or special tools. As the winding process begins, the rollers continually grip the core in response to the torque being transmitted - more torque means higher grip force. The chuck functions in both directions so the web can be pulled either way without changing the chuck's position. A simple turn of the roll in the opposite direction unlatches the chuck for easy removal of the core.

Because the chuck has a minimal number of moving parts, it is very durable and requires little maintenance. The urethane rollers provide non-slip engagement of the core without causing damage. In addition, they will grip virtually any core material, including fiber, metal, composites, or plastics. The patented design of the chuck's hex features a detent which allows the latching action, and ensures concentric expansion. With concentric expansion, rolls don't bounce, making it easier to control web tension and subsequent product quality. The chuck features a split flange clamping system for easy installation and repositioning and it takes just seconds to securely fasten an LC-1000 in place.

With other core holding devices, changing rolls is a tedious process taking valuable time away from production. Cones or wedges often get stuck in cores, requiring even more valuable time to remove them. The LC-1000 is impossible to get stuck in a core - roll changes are effortless, and injuries are eliminated by ending the need to remove jammed cores with a hammer. With the LC-1000, there are no more of these time consuming problems.

The LC-1000 is often used in through shaft applications in conjunction with a simple collar which helps to stabilize wider rolls. It is available with or without a flange, in varying lengths, and in diameters starting at three inches.
