Rotogrip rotation core chucks use the torque produced by the braking force and the opposite web tension (coupled with a brake or motor) to expand the sector elements in order to block and centre automatically the reel core.
The sector elements, with a wide contact surface, ensure maximum control of the reel and reduce damages to the cardboard cores, which can be therefore used again.
Flexibility is another important characteristic of Rotogrip chucks: depending on the application, the fixing flange can be made on customer's request, are available different dimensions, with mono or double diameter and for cores from 3" to 12".
