ABSTRACT:
During the production of a yarn, and independently of fiber feeding into the spinning element, the air circling together with the opener roller during spinning is removed from the area of the housing which does not convey fibers by an auxiliary air stream which is so strong that it removes fibers and fiber fragments that have become detached from the opener roller and are circling with the opener roller. The auxiliary air stream removed from the housing is introduced into the spinning rotor in such manner that the fibers which are conveyed with it are deposited on the fiber collection surface. To remove the auxiliary air stream, an auxiliary channel is provided which is connected to the source of negative pressure independently of the fiber feeding channel and at the same time may let out into the spinning element.
