  • Patent number: 3972206
    Abstract: A knitting unit selection device for a knitting machine includes a plurality of pivotable knitting unit actuators which are aligned in one level of the machine and which cooperate with guiding cams to be brought into the influence of a single magnetic actuator at each of a pair of selection positions of the machine. The magnetic actuator includes a permanent magnet and a field-weakening electromagnet disposed at each of the selection locations of the machine. A pair of spaced cam-lifting arrangements are individually associated with the selection positions for moving certain of the needle units between a disengaged and a knit position and between a disengaged and a tuck position, respectively. Each of the cam lifters are so located relative to the successive needle units that the movement of the needle unit into engagement with the cam lifter when such unit is selected is identical for each of the cam lifters.
