ABSTRACT:
In an automatic textile winding machine comprising a driving cylinder on which rests a slubbing bobbin for being driven thereby, a device for automatically forming an initial bight of a roving around the slubbing bobbin at the commencement of winding comprises a suction nozzle for receiving the leading end of the roving emerging from the nip between the driving cylinder and the bobbin and a reciprocating bight-forming finger which, in moving between a rest position and an operative position, engages the roving extending between said nip and said suction nozzle, and lays it around the bobbin, an air jet carried by the finger then serving to blow the leading end of the roving into the nip between the bobbin and the driving cylinder again.
