Pivotable Positioning Roller in the Reversing Winder

A winding device (1) for winding up a web-like material (2), which comprises a roll core (5), on which the web-like material (2) may be wound up into a material roll, and a web guiding roller (3), which guides the web-like material (2) before or when it reaches the roll core or the material roll, and a pressing element (6), which presses the web-like material onto the roll core or the roll after it already rests on the roll core or the roll, the pressing roller being movable in relation to the roll core. The pressing element (6) is mounted at both ends in lever arms (12) forming a lever arm pair. The lever arms are mounted so they are rotatable, so that the pressing roller is pivotable around the bearing points (13) of the lever arms.
