METHOD FOR PROCESSING A STRAND-SHAPED FIBER SLIVER, AND ROVING FRAME MACHINE

A method for processing a strand-type fiber bundle includes sending the fiber bundle to an air nozzle of a pre-spinning machine used to produce roving. A twist is imparted to the fiber bundle via a vortex air current within the air nozzle to form the roving, wherein the roving leaves the air nozzle...

Beschreibung
Zusammenfassung:	A method for processing a strand-type fiber bundle includes sending the fiber bundle to an air nozzle of a pre-spinning machine used to produce roving. A twist is imparted to the fiber bundle via a vortex air current within the air nozzle to form the roving, wherein the roving leaves the air nozzle through an outlet and is deposited in a receptacle. Normal operation is interrupted in a stop phases during which roving is not produced by the air nozzle. A start-up phase is commenced between the stop phase and subsequent normal operation wherein the roving produced during the stop phase is discarded after leaving the air nozzle when quality of the roving does not meet a desired specification. The roving discharge is deactivated when the quality of the roving meets the desired specification and the roving removed by the roving discharge is separated from the roving.
