Abstract
The invention relates to a method for reeling up, in which a paper web or the like is continuously reeled on a reeling core. The formation of the paper reel is controlled at least by means of an actuator ( ) of the reeling core ( ), advantageously by means of a centre-drive, an actuator ( ) of a primary surface drive device ( ) of the paper reel, and a nip load (N ) effective between the outer perimeter of a paper reel ( ) formed on the reeling core ( ) and the outer perimeter of the primary surface drive device ( ) of the paper reel, said nip load being produced by means of an actuator ( ), a so-called nip load device. According to the invention the torque (M ) produced by the actuator ( ) of the primary surface drive device ( ) of the paper reel is selected to be smaller than the sum (&Sgr;M ) of the torque values produced by the other actuators driving the paper reel that is being formed.
