Abstract:
This invention relates to a method of controlling the operation of a winder in which method while forming at least one fiber web roll the fiber web is brought on the web roll via a nip formed by a first support drum and the web roll, which first support drum is driven by a first drive assembly ( 20 ) applying controllable torque to the drum and the winding force is applied to the web roll by a second drive assembly ( 22 ). In the method the second drive assembly ( 22 ) is controlled based on the indicative speed difference of the second drive assembly ( 22 ) and setting a friction coefficient for determination of maximum winding force.

Claim (Index 1):
A method of controlling operation of a winder for a fiber web while forming at least one fiber web roll, comprising the steps of:\n guiding the fiber web onto the web roll via a nip formed between a first support drum and the web roll; applying a controllable torque to the first support drum with a first drive assembly; applying a winding force to the web roll by a second drive assembly; wherein the winding force is controlled by executing at least the following steps: (a) setting an initial value for an indicative coefficient (\u03bc n ); (b) determining a set value for the winding force using a function F s =f(\u03bc n , N) wherein: F s =set value for winding force [N/m], \u03bc n =the indicative coefficient, N=nip force [N/m] at a nip over which the winding force is transmitted, (c) at least the second drive assembly is controlled by using the set value for the winding force; (d) determining a first indicative speed of at least one of the first drive assembly and the first support drum, and determining a second indicative speed of the second drive assembly; (e) comparing the second indicative speed with the first indicative speed, and determining a difference value; (f) when the difference value, is different than a predetermined set difference, the indicative coefficient value is corrected; and (g) the steps (b) to (f) are repeated so long as the winder is in operation.
