ABSTRACT:
After yarn breakage, yarn loops are formed in an accumulator device (3) by rollers (13, 13') that are able to be displaced in relation to each other. The beam is rotated in reverse at a specific reverse speed (c) which is less than the accumulation speed of the accumulator rollers (13, 13'). The length difference arising from the difference between both the speeds is compensated by further withdrawal of yarns (a) from the creel (1) while the yarns are subjected to a defined braking tension of the individual yarn tensioners (7). Complex controls and speed synchronization are thus avoided.
