ABSTRACT:
The roving slubbing at the conclusion of winding of a roving bobbin in a flyer type machine is passed in a descending spiral around the cylindrical body bobbin and then onto the lower winding cone, after it is looped in an overwinding onto the winding tube below the lower winding cone. The winding then passes in a spiral upwardly and is formed into a short spiral segment which is drawn out by a traction on the roving so that the latter will break along the cylindrical body. The bobbin is stable and can easily be handled and transported directly and there is a reduced possibility for the slubbing to come loose, although it remains available to be pulled downwardly at the ring-spinning machine.
