Abstract
A thread supply device for multi-system circular knitting machines has at least one warp beam accommodated rotatablhy in a receiving frame. On the warp beam are wound the threads associated with the individual knitting systems in the form of adjacent thread winding areas with equal axial lengths and equal diameters. The warp beam is connected with a drive and driven thereby in such a way that it always delivers to the knitting systems the average thread quantitites consumed thereby during operation of the circular knitting machine irrespective of the momentary diameters of the thread winding areas.
