Abstract

Apparatus and process for at least one of winding a material web onto and unwinding a material web off of a winding roll. The apparatus includes a winding roll and a support device, adapted to be positioned against a circumferential portion of the winding roll, that includes a plurality of rotational axes arranged substantially parallel to each other and substantially parallel to a winding axis of the winding roll and a plurality of rotatable rollers arranged on the plurality of rotational axes. The plurality of rotational axes are swivelably coupled to one another substantially perpendicularly to the rotational axes. The process includes turning the winding roll, horizontally tensioning a support device formed as one of a belt and chain, upon attaining a predefined roll diameter, supporting a circumference of the winding roll from below with the support device, and vertically moving ends of the support device at a rate of speed less than approximately a rate of change of diameter of the winding roll.
