A winding machine and method for winding a material web onto a reel-spool in which the material web is transported over a support roll and a winding nip is formed between the support roll and the reel-spool. For changing of reel-spool, the material web is weakened before the support roll in the web travel direction. The material web is then separated at the weakened point. The winding machine includes a rotatable perforating unit, the perforating unit provided with a plurality of one of cutting elements and perforating elements and a counter-holder is arranged on an opposite side of the web from the perforating unit, the perforating unit and the counter-holder are movable relative to one another to weaken the web. The winding method includes providing a rotatable perforating unit adjacent the web, the perforating unit being provided with a plurality of cutting elements providing a counter-holder positioned on an opposite side of the web from the perforating unit and mounting at least one of the perforating unit and the counter-holder so as to be movable relative to another to engage and weaken the web.
