ABSTRACT The invention relates to a web winding method and a winder for carrying out core replacement in a support drum winder. The core replacement is carried out with a sequence of measures, where the cutting of the web, removing of completed rolls (3) and placing of a new roll core between the support drums (1,2) is carried out by one single device comprising cutting, pushing and feeding means. The web (18) is held unmovably towards the trailing support drum (1) during the core replacement by means of a retainer device (16,17). For forwarding the removal of the rolls these are lifted by the same retainer device, if needed, to a height as required by the pusher device.
