MACHINE FOR PRODUCING BOBBINS OF YARN WITH SUPERIMPOSED WINDING POSITIONS WITH MULTIPLE MOTOR DRIVES

The machine comprises a plurality of winding stations (1A) mutually aligned on at least one operating front. Each winding station comprises at least one feed zone (15) for feeding a plurality of yarns (F1; FC) toward a corresponding underlying plurality of mutually superimposed winding positions (17). Each winding position comprises a support (41) for a tube on which one of said yarns is wound to form a bobbin (B3), a motorized winding roller (43) arranged to be in contact with the bobbin being wound,and a traversing device (45), to distribute the yarn in helical turns around the bobbin being formed. Moreover, each winding station comprises at least four mutually superimposed winding positions(17A-17D), with four paths for respective yarns from the feed zone(15) to the winding positions. Further, the four winding positions are divided into two pairs,each of which comprises a respective motor drive system, separate and independent with respect to the other pair.
