Abstract
In textile machines that produce cross-wound bobbins, especially open-end spinning machines, the yarn is laid onto the cross-wound bobbins with yarn guides. The yarn guides are commonly reciprocated with a driven traversing rod. All the yarn guides of the work stations located next to one another are driven simultaneously by this traversing rod. For the sake of uniform laying of the yarn and so that the traversing rod will not sag under tensile and compressive strain, careful rectilinear guidance of the traversing rod is required. Four successive support rollers each are angularly distributed about the circumference of the traversing rod in such a way that, viewed in the circumferential direction of the traversing rod, mutually identical wheel flanges are always adjacent to one another. Those support rollers which are adjacent with respect to the circumference of the traversing rod and whose wheel flanges are toward one another each have the same angular spacing relative to the other two support rollers.
