ABSTRACT:
A machine producing cross-wound bobbins or cheeses has a drum winding a yarn travelling in a given yarn travel direction on a cheese over a given traverse winding width with reversal points. A traverse winding apparatus includes a traction mechanism transmission having an endless traction mechanism. The traction mechanism is guided over rollers defining first and second traction mechanism segments movable in opposite directions at the same speed. The traction mechanism includes yarn entrainers spaced apart by at least substantially twice the given traverse winding width. First, second and at least one further yarn guide are in alternation with the traction mechanism segments as seen in the given yarn travel direction for supporting the yarn during traverse winding and for transferring the yarn between the yarn entrainers at the reversal points. Each of the yarn guides has a concave yarn guide contour with decreasing depth as seen in the given yarn travel direction to be contacted by the travelling yarn.
