More Information
Summary:A control magnet assembly (10) for a pattern apparatus in knitting machines, for electrically controlled needle selection, has selection magnets (29, 30), which are provided with permanent magnetic retaining pole zones and with control pole zones with which control coils (42, 43; 52, 53) that are triggerable in accordance with the pattern are associated, and against which armature elements (26) operatively connected with the needles (18) can be brought. In a control magnet assembly (10) of this kind, optimal magnetic conditions in the control pole zone are to be provided such that a uniform and reliable throwing off of the appropriate armature elements (26) is always attained. To this end, a measuring head (15, 25) is provided for detecting the magnitude of the magnetic field in the control pole zone, and a circuit layout is provided between the measuring head (15, 25) and the control coil (42, 43, 52, 53).
