发明名称 METHOD IN WINDING
摘要 <p>PCT No. PCT/FI96/00570 Sec. 371 Date Jun. 30, 1997 Sec. 102(e) Date Jun. 30, 1997 PCT Filed Oct. 29, 1996 PCT Pub. No. WO97/16367 PCT Pub. Date May 9, 1997A method and apparatus in winding, wherein a number of separate rolls (13a, 13b, 13c, 13d, 13e, 13f) are formed side by side around separate roll spools (15a, 15b, 15c, 15d, 15e, 15f) placed one after the other while supported by support numbers (11, 12). In order to reduce the friction coefficient of the roll spools (15a, 15b, 15c, 15d, 15e, 15f) before, or at the same time as, the roll spools are placed in the winding position, the ends of the roll spools are treated with an agent that reduces the friction coefficient, or pieces of a material that has a low friction coefficient are placed at the end of the roll spools, and/or the axial thrust force between the roll spools is lowered by passing a pressurized medium through the spool locks.</p>
