Abstract
In the case of an open-end spinning machine, a suction roller is provided which serves to transport a fiber veil, expanding transversely to the circumferential direction of the suction roller, to a yarn formation line. The length of the transport path and the width of the fiber veil are determined by defining edges of a suction insert located inside the suction roller. At least one of the defining edges extends at least along a section of the transport path at an acute angle to the circumferential direction. Thus the fiber veil is widened in comparison to the sliver-shaped fed fiber material and/or the fiber tip at the beginning of the yarn formation line is shortened.
