Abstract
A web is wound onto a core (21) while supported by winding drums (11, 12). The web is cut by a cutting device (19), and a finished web roll (10) is removed by a transfer device (16). A new core (21) is moved to a space between the winding drums (11, 12), and the winding is stopped to remove the finished roll (10) and to start a new roll. The core is moved onto support of one winding drum and a support member (22) and held in place by the support member (22) until the movable winding drum (11, 12) has been moved to the starting position of winding.
