  • Apparatus for winding a yarn round a bobbin
    Patent number: 3971517
    Abstract: A guide roller is traversed substantially in parallel to the axis of an uprightly supported bobbin at a speed slow enough not to form appreciable twilled angles of a wound yarn. The yarn continuously extruded from a spinning apparatus at a speed higher than 2000 m/min is introduced substantially in parallel to the axis of the bobbin and changes its direction to right angles with respect to the axis of the bobbin while travelling through the guide roller. The guide roller traverses with shorter traverse strokes as the diameter of the wound yarn becomes larger.
