Abstract
The invention concerns a method in winding of a web in a centre-drive winder, wherein the roll that is being formed is loaded and/or supported by means of a rider roll unit ( ) whose position can be varied and which consists of at least two rolls ( ). In the method, the force that is applied by the rider roll unit ( ) to the roll face in the radial direction and/or the distribution of said force between the rolls ( ) in the rider roll unit ( ) is/are measured by means of a detector of detectors ( ) directly connected with the winding head of the rider roll unit ( ). The nip force of the rolls ( ) in the rider roll unit ( ) and/or the distribution of said nip force is/are regulated on the basis of the measurement signal given by the detectors.
