Method for controlling the structure of a fibrous web roll, for example, a paper or board roll

摘要

The structure of a fibrous web roll is controlled by winding a fibrous web (W) into a fibrous web roll ( 15 ) through a winding nip (N) between the fibrous web roll ( 15 ) being formed and a winding drum ( 13 ). The structure of the fibrous web roll ( 15 ) being formed is controlled by regulating the direction of passing the web to a windup, thereby regulating the wrap angle.
