ABSTRACT:
The device has: a first interlacing jet (19); a feed path of the covering yarn (FT) and a feed path of the elastic yarn (F1; F2) towards the first interlacing jet; supporting elements (37A,37B) for spools of elastic yarn (R1, R2); winding members (54) to wind the composite yarn (FC) on the cop being formed (BC); an interruption device to interrupt feed of composite yarn to the cop being formed and start winding the composite yarn on a new winding tube. The supporting elements for the spools of elastic yarn are suitable to support at least a first spool of elastic yarn and at least a second spool of elastic yarn; associated with the first interlacing jet are a retaining member (20) to withhold an initial free end of the elastic yarn of the second spool and a deflecting element to withhold an initial portion of the second elastic yarn during delivery of the first elastic yarn to the interlacing jet; a sensor to detect interruption of feed of the first elastic yarn to the first interlacing jet; a control to control release of the initial portion after interruption of feed of the first elastic yarn has been detected.
