DEVICE FOR PRODUCING CLADDED YARN

摘要

The invention is directed to a device (1) and a method for making of cladded yarn (9) on a ring spinning frame. The device (1) comprises a first creel (10) foreseen to hold at least one bobbin of roving (8), a second creel (12) foreseen to hold at least one bobbin of cladding yarn (13) and a draft control device (15) suitable to adjust the draft of the cladding yarn (13) before entering the spinning process. Furthermore, the device (1) comprises a monitoring device (22) to monitor the presence of the cladding yarn (13) and to interrupt the supply of the roving (7) to a related drafting unit (2) if the cladding yarn (13) is not present. The cladding yarn (13) is introduced into the spinning process by an injector (27).
