GRIPMATIC
Are you looking for a core chuck easy to use and to maintain? With the simple and reliable design of the torque activated core chucks is it possible to achieve consistent tension at any run speed with little to no maintenance.
Torque activated chucks
Renova‘s torque activated chucks guarantee the most reliable web tension with the minimum maintenance
Product videoTutorial videoGripmatic torque activated chucks are mainly used on winders and unwinders in the paper and corrugated industries.
They use the movement of the reel to expand the gripping jaws elements in order to automatically block and center the reel core. The simple but innovative operating principle of these chucks guarantees high performances even in dust-filled environments as the jaws expand just by rotating around a central cam.
All chucks are designed to avoid core damage and can be cleaned directly on roll stand and are 100% customizable.

TORQUE ACTIVATION
Torque activated chucks use the movement of the reel to automatically block and center the reel core. The cam at the center of the chuck rotates and pushes the expansion elements, or sectors toward the reel core ensuring high performance even in the dust-filled environments.
All models are 100% customizable.
DIFFERENT CAM DESIGNS
Three distinct cam designs can be coupled with different adapters to compose the mechanical chuck that best fits your application needs.
Each cam design uses a proven technology suitable for varied applications.
Trilobate
Simple design trilobate cam, with no rollers and no pins. The large central cam allows a large expansion range and smoothly keeps jaw opening even through dust and other debris.
Exalobate
The exalobate cam has a double pin activation for a smoother and faster expansion.
This design employs rolling friction instead of the sliding one.
Patented
Innovative design with auto neutral position and minimal engagement angle from loading to full contact. It allows reduced core thickness and accepts short cores.
FEATURES
CAGE
High load capacity cage, all nickel coated with anti-rust treatment. Cage and flange pin are both made out of a forged and homogeneous material to maximize strength and reliability.
NOSE
Customizable nose designed to meet every operational need.
JAWS
Huge contact area for maximum chuck-to-core contact. The no-fall-down system eliminates the dropping of the jaws while removing the adapter for cleaning purposes. Available in different finishes: smooth, grooved or in carbide.
OPTIONALS
With the quick-change expansion unit, jaws remain in the adapter during size change and for cleaning.
