Abstract

A winding device for winding up a web-like material has a roll core, on which the web-like material is wound up into a material roll, and a web guiding roller, which guides the web-like material before or when the web-like material reaches the roll core or the material roll, and a pressing element, which presses the web-like material onto the roll core or the roll after the web-like material already rests on the roll core or the roll. The pressing element is movable in relation to the roll core, and is mounted at both ends in lever arms forming a lever arm pair. The lever arms are mounted so as to be rotatable, and so that the pressing element is pivotable around bearing points of the lever arms.
