| Abstract | The invention solves the problem of yarn spinning-in in open-end spinning machines with high-speed rotors, and particularly eliminates deformations of yarn end, due to impacts thereof onto opposite rotor walls while being returned into the rotor. Such deformations reduce the strength of splicings. According to the invention, the yarn end (29) is moved back and stopped for a short time in an intermediate position between the inlet (17) of the take-off duct (15) and a collecting groove (12) and then it is conveyed by another backward motion to a fibrous ribbon in said groove (12). |
