  • Method of controlling operation of a winder for a fiber web
    Patent number: 10526155
    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.

  • Method and apparatus for threading a fibrous material web in a winder
    Patent number: 8500057
    Abstract: A method of adhesive-free threading of a fibrous material web for winding around a winding body includes the steps of diverting the fibrous material web in the circumferential direction of the winding body, guiding the fibrous material web with its unfolded leading edge ahead in the direction of a nip formed between the winding body and a drum and catching the leading edge of the fibrous material web by interaction with the fibrous material web and/or the winding body. An apparatus for adhesive-free threading of a fibrous material web for winding around a winding body has a diverting device for diverting the fibrous material web in the circumferential direction of the winding body and a mechanical guide for guiding the fibrous material web with its unfolded leading edge ahead in the direction of a nip formed between the winding body and a drum.
