Abstract: A machine for the production of knitted goods includes a plurality of stitch-forming elements, at least one stitch-forming location, an associated spinning device at the at least one stitch-forming location, at which a sliver (FB) or a yarn is produced from a roving yarn (VG) and the sliver (FB) or yarn is fed to the stitch-forming elements. The spinning device has separate drive devices, which can be actuated in a manner that enables the spinning device to produce a sliver (FB) or a yarn of variable thickness from roving yarn (VG) and which can be fed to the stitch-forming elements.

Abstract: A drafting device for spinning-knitting machines includes a drafting arrangement with which at least two roving yarns can be drawn parallel to form fiber strands and at an outlet of which a nozzle unit with twist nozzles arranged parallel to one another for each of the drawn fiber strands is arranged. Between the inlets of the twist nozzles, the nozzle unit is provided with a respective plate-shaped separator projection that extends up to a withdrawal roller pair of the drafting arrangement.

Abstract: Drawing equipment for a knitting machine for the production of a fiber material from a roving includes double belts, guided via a pair of belt rollers and a pair of output pressure rollers. The pair of belt rollers and the pair of output pressure rollers respectively have an upper roller and a lower roller, which is driven by an electric motor. All of the drawing equipment rollers are disposed on the front-side of a base plate. Axles of the rollers are guided through the base plate. Drive means for the lower rollers of any roller pair are disposed at least partially on the rear-side of the base plate. Disposed on the upper roller of the pair of output pressure rollers and on the upper roller of the pair of belt rollers is suction equipment which extends over both of the upper rollers.

Abstract: A drafting arrangement for a knitting machine for the production of a fiber structure includes a roving with double aprons guided over apron rollers and an output roller pair. The apron rollers and the output roller pair respectively have a press roller and an electric motor-driven drive roller and the rollers and the electric motors are arranged on the front side of a base plate. Motor shafts are passed through the base plate and are connected by means of drive devices to the shaft members of the drive rollers. A clamping device is provided on the rear side (18) of the base plate (11) to press apron rollers and the output roller pair against the drive rollers.

Abstract: A method and a knitting machine for producing a knitted product composed of fiber material fed by a roller pair (11c) are described. The stitches are formed as usual by knitting elements (3) being raised out of a non-knitting position into a fiber take-up position, while at the same time previously formed stitches are being knocked over, and being withdrawn again after the fiber material (6) is inserted. The presence of fiber material is monitored by means of a sensor (22), which when there is no fiber material present emits an error signal, as a result of which the knitting elements are prevented from being raised further into the fiber take-up position. According to the invention, when the error signal occurs, the knitting elements (3) are withdrawn from an intermediate position again without the previously formed stitches being knocked over and without the fiber material being taken up.

Abstract: A machine for producing a knitted product by at least partly using untwisted fiber material (4) includes at least one stitch forming system, on which stitch-forming elements (3) can be brought into a fibre pick-up position. A thread guide (27) is associated with the stitch-forming system and has a passage (30) for the fibre material (4). A drafting assembly (9) is associated with the stitch-forming system for attenuation of the fibre material and a spinning device (15), which is arranged between the drafting assembly (9) and the thread guide (27) and contains at least one spinning element (16) working with a blast air flow and a transport tube (17) connected thereto. The transport tube (17) contains an outlet end (17d) for the fibre material opening into the thread guide (27). The outlet end (17d) has an inner cross-section (D2), which is exactly the same size as or smaller than an inner cross-section (D1) at an outlet end of the passage (30).

Abstract: A device for transporting fibre material between a drawing frame and a loop-forming machine is described. The device contains at least two transport units which are disposed in succession and have respectively one inlet- and outlet opening, said transport units being formed from respectively one twisting member (16a, 16b, 16c) and one transport pipe (17a, 17b, 17c) connected thereto, there being provided between an outlet end (28) of a preceding transport unit (16a, 17a) and the inlet end of a subsequent transport unit (16b, 17b) a gap (27a, 27b) which is intended for forming an air removal opening. According to the invention, a suction device (31a, 31b) is disposed in the region of this gap (27a, 27b) (FIG. 4).

Abstract: The invention relates to a machine for the production of a knitted fabric using stretched fiber material (4). The machine comprises a stretching device, a spinning device having a spinning element, a transport pipe (17) connected thereto, and a thread guide (27) equipped with a passage (30) for the fiber material (4). According to the invention, an exit end (17d) of the transport pipe (17) has a cross-section (D2), which is as large as, or smaller than, an inside cross-section (D1) on an exit end of the passage (30). The intensity of the air blast current is selected such that it enables sure insertion of the fiber material (4) in the needles of the machine forming the loops.

Abstract: A knitting machine is described, which includes at least one carrier provided with knitting tools (2, 3), a cam mechanism with at least one knitting point (71) for moving selected knitting tools (2, 3) into a yarn pick-up position and a striping attachment for feeding selected yarns to the knitting tools (2, 3) brought into the yarn pick-up position. According to the invention, the striping attachment has at least one first and one second yarn changing device (73, 74) such that yarns (78, 79) fed optionally by the first or the second yarn changing device (73, 74) may be laid into the knitting tools (2, 3) brought into the yarn pick-up position at the knitting point (71) (FIG. 12).
