Abstract
A control magnet system for a pattern apparatus on a textile machine, in particular a knitting machine, comprises a permanent magnet which includes a control pole having a pole surface and controllable by means of a control coil and a co-operating pole having a pole surface, and comprises at least one armature which is movable relative to the two poles and which can be applied against the pole surface of the control pole against a spring force in such a manner that, when the control coil is not energized, the armature remains against the pole surface of the control pole by virtue of the magnetic force produced by the permanent magnet, whereas, when the control coil is energized the armature is released from the pole surface of the control pole by virtue of the spring force, wherein the pole surface of the control pole is perpendicular to the direction of release of the armature, and the pole surface of the co-operating pole is perpendicular to the pole surface of the control pole (FIG. 2).
