METHOD AND DEVICE FOR WINDING A PAPER OR BOARD WEB

摘要

The invetion realtes to a method in winding, wherein separate rolls are formed side by side around roll cores (10a, 10b) placed one after the other while supported bz support members and wherin the roll cores (10a, 10B) are pressed at their ends against one another by means of core chucks (20) arranged in connection with the free ends of the outermost roll cores (10a, 10b). In te method, the roll cores (10a, 10b) are placed in a desired position and subjected to a desired compression force by means of the core chucks (20), the lenght of the row of the rool cores (10a, 10b) is determined, and the compression force of at lest one core chuck (20) is regulated during winding when the lenght of the roll core row changes to keep the compression force and/or the lenght of the roll core row within desired limits. The invention also relates to advice in winding wherein separate rolls are formed side around roll cores (10a, 10b) placed one after the other while supported ba support member, which device is a core chuck (20) arranged in connection with the free ends of the outermost roll cores (10a, 10b). At least one core chuck (20) comprises measuring devices (21, 23) for measuring the position and the compression force of the core chuck (20) and control devices (22) for controlling the opeation of the coree chuck (20) to keep the position and the compression force of the core chuck (20) as desired.
