ABSTRACT:
A winder for winding a running web. The winder includes a backing roll having the width of the web and a winding drum on which the web is wound into a roll. A first pair of swivel levers (primary levers) each has a fork on one end for receiving a journal of the winding drum, and is mounted at the other end in the area of the backing roll axis such 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 backing roll and passes the primary section until reaching a second position. In the second position the winding drum, with the as yet incomplete paper roll, is taken over by a second pair of swivel levers (secondary levers). An essentially horizontal guideway extends from the second position across a secondary section up to a third position. A contact pressure device forces the winding drum with the paper roll being created on it down on the backing roll. A separate support beam is provided on each machine side (tending side and drive side) which relieves the winding drum/paper roll indirectly or directly at least on the primary section. Each support beam is designed and arranged so that the winding drum/paper roll, or its journal, can roll on it. At least one end of each support beam is movable to relieve the winding drum/paper roll.
