Abstract:
1. A method of winding comprising the steps of: forming separate rolls, each roll having two ends, wherein the separate rolls are formed side by side around roll cores placed one after the other to form a row of rolls, and thereby define outermost roll cores which have free ends, the separate rolls being formed while supported by support members; pressing the roll cores at their ends against one another by two core chucks arranged in connection with the free ends of the outermost roll cores, placing the roll cores in a selected position and subjecting the roll cores to a selected compression force by the core chucks; measuring the length of the row of rolls with a position sensor and a compression pressure sensor forming part of one of said two core chucks; and regulating the compression force of at least one core chuck during winding within selected limits with respect to at least one of the compression force or the length of the roll row.
