Abstract: A needle cylinder of a circular knitting machine includes a cylinder jacket having axial needle channels, knitting needles movable therein and an upper cylinder end for stitch formation having a radial groove between pairs of adjacent needle channels each having an insert forming a stitch formation surface with its insert surface protruding from the groove. Exchangeable, stitch formation surfaces form quickly replaceable inserts. Each insert is a spring lug including a lug foot overlapping the upper cylinder end at the side of the cylinder jacket or the side edge of an outer ring channel in the upper cylinder end and a lug terminal with a terminal part springily engaging behind a counter support projecting at the upper cylinder end at the cylinder's inner side or a side edge of an inner ring channel in the upper cylinder end. A circular knitting machine with the needle cylinder is also provided.

Abstract: A device for producing knitted fabric comprising a knitting machine and a roving drawing and strengthening unit. The roving drawing and strengthening unit has a roving supply unit, through which a roving can be provided in the form of a fiber bundle that has not been strengthened, a stretching unit, to which the roving can be fed in a conveying direction in the form of at least one sliver, and a spinning nozzle device, through which compressed air can be applied to a drawn roving exiting the stretching unit in a fiber strengthening segment.

Abstract: The invention relates to a device for producing knitted fabric comprising a knitting machine and at least one roving drawing and strengthening unit. The at least one roving drawing and strengthening unit has a roving supply unit, by means of which a roving can be provided in the form of a fiber bundle that has not been strengthened, a stretching unit, to which the roving can be fed in a roving conveying direction in the form of at least one sliver, and a spinning nozzle device, by means of which compressed air can he applied to a drawn roving exiting the stretching unit in a fiber strengthening segment. The invention further relates to methods for producing knitted fabric by means of a knitting machine and at least one roving drawing and strengthening unit.

Abstract: A method for producing knitwear formed at least partially as single jersey knitwear with a perforated structure and a functional textile based on the knitwear, provide very fine knitting stitches and perforated structures with large holes meeting demands of sportswear and underwear. The knitwear is produced on a double jersey knitting machine with first and second oppositely disposed needle carriers and a machine gauge of >24 needles/inch. The first needle carrier has a needle number/inch of latch-type needles corresponding to the machine gauge and the second needle carrier has transfer needles. The needle number/inch of the transfer needles is at most half that of the latch-type needles of the first needle carrier. The transfer needles form loop accumulations with at least one tuck loop per hole subsequently transferred with or without at least one knitting stitch from the transfer needles onto the latch-type needles.
