ABSTRACT:
To improve the quality of spun yarn, a fiber aligning apparatus is formed in the interior wall of the housing of a sliver feeding and opening device of an open-end spinning machine. The fiber aligning apparatus includes as plurality of aligning elements, which are integrally formed from the wall of the housing, for aligning the individual sliver fibers during their travel within the housing. The aligning elements are formed in a recess in the wall of the housing which extends concavely in the circumferential direction of the cylindrical housing wall. Each aligning element is in the form of an angled tooth projecting inwardly with respect to the housing and terminating in an apex, the tooth apices defining an arcuate extent of the cylindrical surface of the housing concentric with the opening roller of the sliver feeding and opening device.
