Abstract

For winding up of a paper web to form a paper roll, a first reel spool is accelerated to the speed of the web and brought into a first, start-of-winding position in which it forms a nip with a driveable press drum. The beginning of the web of paper is guided around the press drum and is wound onto the first reel spool. When a first layer thickness has been wound, the first reel spool is transferred into a second, complete-winding position and the paper roll is wound up there to its desired layer thickness. During the entire winding process, the press drum or a special press roll are pressed against the winding surface of the developing paper roll, a torque is introduced into the axis of the first reel spool by means of a central drive and the press drum and/or press roll and the first reel spool with the developing paper roll thereon are displaced, preferably exclusively horizontally, without substantial changes in the direction or orientation of those elements. Then a second reel spool is accelerated and brought into the first position before transferring the web to the second reel spool.
