Abstract
The invention relates to a method and an arrangement in connection with a secondary coating line, in which method a fiber, fibers or fiber bundles are unwound from payoff reels (1) and guided to a press (4) by which a secondary sheath is formed around the fiber(s) or the fiber bundles and grease is fed into the secondary sheath, and in which method the assembly formed by the secondary sheath and the fiber(s) or the fiber bundles is pulled at a constant rate and low tension to a winding device (15) through cooling means (5, 6). In order to control the difference in length between the fibers and the secondary sheath, the difference in length between the fibers and the secondary sheath is arranged to be adjusted by adjusting fiber tension by moving the fixing point between the fibers and the secondary sheath along a straight part formed in the relaxation part by using wheel structures (8, 10).
