A double knitting cam unit for knitting machines, with working jacks arrad in the needle channels of the needle beds behind the knitting needles and Jacquard jacks arranged behind these, includes superposed needle cam units (AD), jack cam units (BD) and Jacquard jack cam units (CD) with fixed and movable cam elements. 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. Preferably, the movable transfer cam elements (1/1) are made movable in the needle cam unit (AD) in the longitudinal direction of the needles and the movable acceptor cam elements (8, 9) are provided in the jack cam unit (BD).
A double cam unit for a knitting machine including a Jacquard device having jacks arranged in the needle channels of the needle beds behind the knitting needles, with needle cam units and jack cam units with fixed and movable cam elements arranged in three levels under one another, the cam units being symmetrical about the central line between the two parts of the double cam unit, wherein a jack cam unit level and a Jacquard cam unit level are provided under a needle cam unit level, each needle cam unit is provided with a transfer cam element movable in longitudinal direction of the needles and being symmetrical with respect to a cam cross axis, each jack cam unit is provided with two movable acceptor cam elements for stitch transfer being symmetrical with respect to a cam cross axis, and each jack cam unit is provided with a movable cam element for bringing into actuation all nonselected working jacks and being symmetrical with respect to a cam cross axis.
