A winder for winding a running web of paper, foil or similar, with a backing roll having the width of the web, a winding drum on which the web is wound into a roll, and a first pair of swivel levers (primary levers) each of which features on its end a fork for receiving a journal of the winding drum and being with the other end so mounted in the area of the backing roll axis that the winding drum, while swiveling from a first position above the backing roll in the running direction of the web about the backing roll, approaches the latter and passes thereby the primary section until reaching a second position in which the winding drum with the as yet incomplete paper roll is taken over by a second pair of swivel levers (secondary levers), with an essentially horizontal guideway extending from the second position across a secondary section up to a third position, and with a contact pressure device for forcing the winding drum with the paper roll being created on it down on the backing roll. A pair of cam plates is provided of which each is co-ordinated with a primary lever in such a way that together with it, it passes the primary section at least partly, thereby relieving the winding drum/paper roll according to its contour and according to the section of travel negotiated. The cam plates are co-ordinated by a drive that rotates the two plates about a horizontal axis.
