ABSTRACT:
In the take-up device for web-shaped materials, especially plastic films, there is at least one bearing unit which acts between the ends of the contact roller on its peripheral compressive surface and supports the contact roller. The contact roller is made with a relatively small diameter and is made flexurally soft such that via the bearing unit(s) the bending line and the damping behavior of the contact roller between its ends can be influenced and advantageously also controlled.
