Abstract: In a flat knitting machine with knitting needles which have flexible shanks nd which are arranged in the needle channels of the needle beds, the flexible shanks of the knitting needles are each engaged from below in the region of an operating butt of the needle by a flexible shank of a Jacquard jack whose shank can be held either in an upper or in a lower position with respect to the needle bed. Selectively actuatable selection flaps are provided for selective extension of the Jacquard jacks into positions in which the needles can form stitches or tuck loops.

Abstract: A flat knitting machine includes a device for adjusting the retractor elets for the needles in the cam systems on the carriage of the machine for the setting of the stitch tension. In order to simplify the tension adjusting mechanism and simultaneously to produce a sensitive setting mechanism, there is provided on the carriage a single electrical stepping motor, with position sensor, for counterbalanced adjustment of the leading and of the trailing retractor elements of each cam system.

Abstract: A flat knitting machine has a spool shelf arranged above and behind the nle bed or beds and carriage, the shelf carrying yarn spools and a yarn guide mechanism. In order to make the yarn spools and yarn guide mechanism more easily accessible, the spool shelf is arranged to be displaceable without skewing from a rearward position to a forward position, wherein in the forward position the shelf overlies at least a part of the needle bed or beds and of the carriage.

Abstract: A single or multiple cam unit for knitting machines, with needle feet of knitting needles selectively lowerable by means of a needle selector device into the needle channels of the needle beds, comprises fixed and movable cam elements of the cam units (D) and pressure cam elements (17, 18, 19, 20) for each cam unit (D) cooperating with the needle selector device. In order to effect a transfer of stitches independently of the carriage traverse direction and independently of the transfer direction towards the front, towards the rear or in both directions at the same time, each cam unit (D) is constructed symmetrical about the central axis (M) of the cam unit (D), each cam unit (D) includes a cam element (8) oscillatable in the cam plane for extending the needles during knit-stitch formation as well as a controllable cam element (6) for tuck-stitch formation and, in each cam element (D), fixed transfer cam elements (27,28) and fixed acceptor cam elements (24,23) for stitch transfer are provided.

Abstract: A flat knitting machine with a carriage movable over the needle beds has presser foot wires with free trailing ends arranged in holders to extend in the direction of travel of the carriage in front of the withdrawal positions of the needles. For simple construction and selective utilization of the presser foot device the holders for the presser foot wires are secured on a slider which slides along the needle beds on a thread guide rail, and the slider is selectively entrained by the carriage by means of entraining pins carried displaceably on the carriage. The holders for the stroking-in wires are preferably displaceable vertically towards the needle bed combs.

In order to enable a transfer of stitches independently of the carriage traverse direction and independently of the transfer direction towards the front, towards the rear or in both directions at the same time, the cam units (AD, BD, CD) are made symmetrical to the central line (L) between the two parts of the double knitting cam unit and each needle or jack cam unit (AD, BD) contains movable transfer cam elements (1/1) and each jack or needle cam unit (BD, AD) contains movable acceptor cam elements (9, 8) for stitch transfer.

Abstract: In the needle selection device on a knitting machine equipped with a Jacqd mechanism, the knitting needles can be brought into various positions in which they are inactive, or are active for knitting, for forming tuck loops and for the transfer of stitches, with the aid of cam means on the carriage. In order to create a needle selection device which is simple in structure and is functionally reliable, blocking levers corresponding in number to the number of needle channels and arranged in accordance with the gauge of the needle separation are provided on a mounting rib extending over the length of the needle bed. At each selection position, on the carriage, there is provided a cam element for pivoting the blocking lever and also an electromagnet controllable for needle selection and having associated therewith a tripping pin for pivoting the blocking lever.

Abstract: A straight knitting machine having two needle beds with knocking-over combs isposed in an inverted V-shaped configuration and a sliding carriage located above said needle beds is further provided with horizontal stop edges on said combs beneath the crossover zone of the needles associated with said needle beds for preventing the upward movement of the knitted piece upon activation of the needles. A pair of rotatable heads are mounted on a common support movable with said carriage with each head having a layering device mounted thereon and displaced 90.degree. from a stripping device and a hold down device which are also mounted on each rotatable head. The heads are rotatable at the end of each traversing movement of the carriage so as to locate the layering device and hold down device of one head in advance of the knitting zone and the layering device of the other head in trailing relation to the knitting zone during a subsequent pass of the carriage.

Abstract: The zone of movement of the reciprocating carriage of a flatbed knitting machine is guarded, to prevent injury to the operator, by a light barrier set up between each end of the machine and the carriage. Only the barrier on that side of the carriage towards which the carriage is moving at any given time is effective to trigger braking of the carriage and stopping of the machine if the barrier is penetrated. The carriage may carry a double-sided reflector with combined light emitter/receiver units positioned at each end of the machine.
