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.

Method and device for the accumulation of a yarn overlength between a

An impact element (12, 17), which is connected with a spring device (15), is tensioned through the feed movement of the package carrier rods (5) and, when a trigger position (23) is reached, will be released in such a way that a force impulse (I) is delivered in the direction of the nearest adjacent spindle (6), respectively a remnant package (2) or empty bobbin (3) mounted on said spindle. With that, the impact element transmits a force impulse, first of all onto a lossely mounted impact disc (19) which can be utilised with various bobbin formats and which protects the remnant packages.
