Abstract

A winding accumulator system for controlling the storage of filamentary material between a source of such material and a winding receptacle, utilizing: a plurality of serially interconnected accumulator units for storing filamentary material with the first accumulator unit receiving filamentary material from the source and storing a given amount of filamentary material and each succeeding accumulator unit storing double the amount of filamentary material stored by a preceding accumulator unit; varying the movement of the filamentary material between the accumulator units; and controlling the movement varying device to limit the change in tension of the filamentary material with changes in the acceleration or deceleration of the filamentary material caused by a change in the input or output of filamentary material to or from the accumulator system.
