Abstract (en)

Feeding system (1) for a core spun yarn (3a, 3b) ring-spinning machine (2) comprising first means (11) configured to feed a first continuous filament (9) of elastane from a primary bobbin (10) arranged for "déroulé" unwinding and second means configured to feed a second continuous filament (4) other than elastane from secondary bobbins (7) arranged for "déroulé" unwinding. Said second means comprises a first device (8) for actuating the movement of a first secondary bobbin (7) and for feeding a filament (4b) to a first spinning position (30), and a second device (26) for actuating the movement of a second secondary bobbin (7) and feeding a filament (4b) to a second spinning position (31) adjacent to the first. Said second means further comprises an accessory tool (15) configured to drive the simultaneous dragging of two different continuous filaments (4a) when the first or second secondary bobbin (7) is not present, these different filaments (4a) coming from third bobbins (5) located on a creel (6) of the frame (16) of the spinning machine (2), said accessory tool (15) making it possible to feed said two filaments (4a) to said two adjacent spinning positions (30, 31) with only one of the devices (8), so that the other device (26) is left free to optionally actuate the unwinding of a third continuous filament (29).
