Product info

Rotomatic is the new patented core chuck that combines the quality and technology of the Re torque activated core chucks with a telescopic pneumatic ejector concentric to the core chuck.
The roll ejection system RotoMatic has been designed to solve problems of paper waste and, moreover, to eliminate the problems of unlocking the reels during their ejection.

Rotomatic is made up of the Rotogrip chuck, that guarantees an optimal grip on the reel core without damaging it, and a patented telescopic pneumatic piston that ensures the automatic ejection of the rolls without any manual operation even in the case of deformed or damaged rolls.

Thanks to RotoMatic, it will therefore be possible to increase the productivity of the production plant and significantly increase the level of safety for the operators.

During the loading phase, the core chuck uses the torque produced by the braking force and the opposite web tension to expand the wide surface sector elements to block and centre automatically the reel core. During the unloading phase, the pneumatic ejector generates a coaxial thrust force of 14.500N (first stage) and 5.500N (second stage) to automatically unlock end eject the rolls without any manual operation even in the case of deformed or damaged rolls.

RotoMatic is equipped with a safety valve to avoid overpressure inside the pneumatic chamber and consequent damage to the internal parts of the system. Rotomatic can be installed on any type of unwinder whether it is equipped with an ejection system or without. The flange can be designed according to the customer’s drawing and is available for core chucks from 3” to 6”.
