Abstract (en)
The present invention relates to a procedure for placing a spare or reserve winding consisting of a number of coils on a cop (2) that lacks wound thread or lacks thread wound of sufficient length for being suitable to the operation of automatic reconnection with the small bundle of textile fibers coming out of the last pair of drawing rollers, and it also relates to a device for carrying this procedure into effect. More particularly, said device comprises an auxiliary pivot (6) which is driven for rotation and is arranged near an auxiliary spool (3) which last is laterally provided with a reciprocating thread guide (9). Said device also comprises a variable profile radial cam (21) for guiding the nippers or gripping tools (15) into a number of operative positions.
