The invention relates to a method for winding a web, said method comprising the steps of winding a web roll (11) by passing the web onto a core (12) or the like via a pressure nip (N) formed between a winding drum (10) and the roll (11), whereby the core (12) or the like element is supported by means o f chucks (14) or the like mounted on roll support arms (13). In the method, th e pressing-nip force in the nip (N) formed between the roll (11) and the windi ng drum (10) is controlled using a position-feedback technique in which the movements of the roll support arms (13) are synchronized. The invention also relates to a device for winding a web, said device being intended for use in conjunction with winding a web roll (11) onto a core (12) or the like via a pressure nip (N) formed between a winding drum (10) and the roll (11), where by the core (12) or the like element is supported by means of chucks (14) or th e like mounted on roll support arms (13). The device includes means (15, 16, 1 7, 18, 19, 20, 21, 22) for controlling the pressing-nip force in the nip (N) formed between the roll (11) and the winding drum (10) using a position- feedback technique in which the movements of the roll support arms (13) are synchronized.
