ABSTRACT:
In a false twist spinning unit a fiber sliver is removed from a fiber sliver can and fed into a drafting mechanism. The fiber aggregation delivered by the drafting mechanism is received by a suction portion of a spinning unit and is passed to a twist-imparting element which produces a spun yarn. The spun yarn is withdrawn by a roller pair and passes via a yarn monitoring device to a winding unit. The suction pressure required for the suction portion is produced by a suction device. In the event of blockage of the suction portion, a cleaning element or device is activated. After cleaning of the suction portion is completed, spinning is restarted.
