Abstract
In paper winding, separate rolls are formed side by side around roll cores () placed one after the other while supported by support members. The cores are pressed at their ends against one another by core chucks () arranged in connection with the free ends of the outermost roll cores (). The roll cores () are placed in a desired position and subjected to a desired compression force by the core chucks (), the length of the row of roll cores () is determined, and the compression force of at least one core chuck () is regulated during winding when the length of the roll core row changes to keep the compression force and/or the length of the roll core row within desired limits.
