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: A slider needle for knitting machines, particularly flat knitting machines, omprises a needle body with needle hook and needle butt, and a slider with a slider butt and mounted to be displaceable relative to the needle body. In order to produce a slider needle of simple construction with the needle butt capable of being depressed into the needle bed, the needle body consists of a guide shaft provided with a slot for receiving and guiding the slider and a flexible shaft extending from the guide shaft and projecting rearwardly from the guide shaft towards the needle butt, with the flexible shaft carrying the needle butt and being engageable from below in the needle channel by a tilting lever.

Abstract: A slider needle for knitting machines, particularly flat knitting machines, omprises a needle body with needle hook and at least one needle butt, and a slider equipped with slider foot and mounted to be displaceable relative to the needle body. In order to ensure trouble-free and reliable separation of the old stitches from newly laid yarn a short swivel detent is mounted on the needle body behind the needle hook. The length and shape of this swivel element is chosen so that in the normal position of the needle, with the needle hook closed by the slider, the swivel detent is masked by the slider in the vertical direction, while when the needle hook is open the swivel detent projects proud of the needle body and above the slider in both its end positions.

Abstract: A flat knitting machine with a carriage movable over the needle beds incls stroking-in wires mounted in holders on the carriage with free wire ends trailing in the direction of carriage traverse in front of the withdrawal positions of the needles. These wires are moved into and out of their working positions at the regions where the carriage reverses its direction of movement. In order to make possible a selectively controlled switching of the stroking-in wires into and out of effective operation, indexing cams engageable with entraining fingers on the holders are arranged on the machine frame to be displaceable perpendicular to the longitudinal axes of the needle beds, and lifting cams which can be switched into and out of action are mounted on the carriage for selective displacement of the indexing cams on the machine frame.

Abstract: A left-left flat knitting machine is comprised of two needle beds and kning needle sets arranged in a common plane, with needle hooks provided on both ends of the needles and with bars to activate the knitting needles in the needle bed channels of both needle beds.

A carriage traversible the length of the beds includes a cam assembly for imparting knitting and loop transferring motions to the needles in all the beds. By selective co-operation of the several beds flat and tubular knitted fabrics of any known design can be produced.

Abstract: A flat knitting machine has two opposed needle beds and rigid loop expanders are provided on the needles. Loop transferring cam sets mounted on the traversing machine carriage include a transfer cam having at least three noses of which at least one is higher than the others. The higher nose lifts the needles sufficiently for the knitted loops held on the needles of one bed to be expanded on the loop expanders and the other noses complete transfer of the loops to the needles in the other bed. The loops open the latches of the receiving needles as they are transferred.
