Abstract:
A device and a corresponding method produce a knitted fabric with a knitting machine and a roving drawing and strengthening unit. The device has a roving supply unit with a roving, a stretching unit linked to the roving supply unit, and a spinning nozzle device provided downstream from the stretching unit in a roving conveying direction of the device forming a fiber strengthening segment by applying compressed air. An end thread gripping roller pair rotatable in opposite directions is provided downstream from the spinning nozzle device in the roving conveying direction delimiting the fiber strengthening segment. The device has a blow-off device for blowing off the spinning nozzle device and/or the stretching unit and a suction device for suctioning off loose fibers from the spinning nozzle device and/or the stretching unit. The suction device and the blow-off device are interconnected in a blow-off and suction system.

Claim (Index 20):
A method for producing a knitted fabric, which comprises the steps of:\n supplying at least one roving to a stretching unit by a roving supply unit; applying compressed air to a drawn roving exiting the stretching unit by a spinning nozzle device in a fiber strengthening segment, being thus strengthened, wherein the fiber strengthening segment is delimited by an end thread gripping roller pair rotating in opposite directions through which a drawn, strengthened roving is led in clamped fashion and an end thread exiting the end thread gripping roller pair is supplied to a knitting machine; blowing off the spinning nozzle device and/or the stretching unit via at least one blow-off device; suctioning off exhaust air by means of at least one suction device on the spinning nozzle device and/or the stretching unit; leading suction air to a suction air cleaning device, in the suction air cleaning device an underpressure is generated by means of at least one ventilation device, through the suction air cleaning device loose fibers are led out of the suction air; and putting cleaned exhaust air gained from the exhaust air under excess pressure, the cleaned exhaust air being under excess pressure is led, starting from the suction air cleaning device, in at least one air channel running along over the end thread gripping roller pair and through at least one channel opening of the air channel by forming at least one air curtain aligned to or along the spinning nozzle device and/or on or along the stretching unit.
