FEEDING SYSTEM OF A CORE SPUN YARN RING-SPINNING MACHINE, CORE SPUN YARN RING-SPINNING MACHINE COMPRISING SAID SYSTEM AND METHOD FOR SPINNING CORE SPUN YARN USING SAID MACHINE

摘要

Feeding system (1) for a core spun yarn ring-spinning machine (2) comprising; first means (11) configured to feed a first continuous filament (9) of elastane from a bobbin (10) arranged for "deroule" unwinding, second means configured to feed a second continuous filament (4b, 29) other than elastane from bobbins (7, 28) arranged for "deroule" unwinding, said second means comprising a first actuator device (8) for actuating the movement of a first bobbin (7) to feed the filament (4b) to a first spinning position (30), and a second actuator device (26) for actuating the movement of a second bobbin (7, 29) to feed the filament (4b) to a second spinning position (31) adjacent to the first spinning position, said system comprises an accessory tool (15) provided with two dragging bodies (18) to simultaneous drag by means of one of said actuator devices two different continuous filaments (4a) coming from bobbins (5) located in an overhead creel (6) when said first or second bobbin (7) is not present, said accessory tool (15) making it possible to feed said two filaments (4a) to two adjacent spinning positions (30,31) with only one of the actuator devices (8), so that the other actuator device (26) is left free to optionally actuate the unwinding of a third continuous filament (29).
