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.
Claims19
A take-up device for web-shaped materials comprising:
- a take-up roller;
- a contact roller which presses the web-shaped material against the take-up roller by means of a peripheral compressive surface;
- and
- at least one bearing unit which acts between the ends of the contact roller on its peripheral compressive surface and supports the contact roller,
- wherein said at least one bearing unit is adjustable in at least two directions which run perpendicular to one another, and wherein the contact roller is flexibly supported such that moving said at least one bearing unit causes a bending line of the contact roller to adjust with respect to the web-shaped material.
