The invention relates to a device in connection with a reel-up of a web, whi ch reel-up comprises at least a reeling means (C) mounted on bearings (7, 8) in the reel-up to guide a web (W) travelling in the reel-up on a reeling axle (T1), a reeling axle (T1) mounted on bearings (7, 8) in the reel-up to reel the web (W) around the reeling axle (T1), which reeling axle (T1) is arrange d to rotate around a direction transverse to the web (W), first control means (1, 3) for setting and controlling the distance between the reeling means (C ) and the reeling axle (T1), second control means (1, 5) for effecting and maintaining a force effect (F1) between the reeling means (C) and the reelin g axle (T1). In the invention the second control means (1, 5) comprise an elastic element (E) that stores energy, to effect and maintain the force effect (F1), in which element (E) a change in a dimesion (D) is proportional to a change in the force effect (F1), and the reel-up comprises sensor means (6) which are arranged to measure said dimension (D).
