Product info

Re friction shafts are the ideal solution for multiple and independent rolls rewinding on the same shaft, as each one needs a proper web tension. During the rewinding process of multiple rolls, obtained after the cutting process of a plastic film or paper or any other material, is it common to have important differences of thickness and, consequently, differences of the web tension.
To solve this issue, the friction shafts ensure a different management of the rolls locking onto one or multiple friction rings the core of each roll to obtain a precise rewinding and a uniform web tension of each roll.

Re friction rings with balls are made of hard black anodized aluminium or steel depending on the width. An inner bearing of spheres increases the sturdiness of the ring, even if made in aluminium, and makes the sliding action more fluid. Friction rings with widths starting at 12,15 mm, can be equipped with preloaded positioners to increase the stability of the reel cores before before the gripping balls engage the core.
