Abstract
With pneumatic feeding of fibers to the fiber collection surface of an open-end spinning element, an auxiliary air stream flowing from the immediate proximity of the feeding device to the inlet into the fiber feeding channel is produced and is sufficiently strong so that it removes circling fiber fragments which have been detached from the opener roller. For this purpose, an air conveying channel is provided in the area between the inlet opening of the fiber feeding channel and the feeding device (as seen in the direction of rotation of the opener roller) in the peripheral wall of the housing. This air conveying channel extends from the immediate proximity of the opening in the housing containing the feeding device in housing to the inlet opening of the fiber feeding channel.
