Abstract
A needle selection device for a flat knitting machine with knitting needleshich are pivotable into different positions comprises pivotable double-armed check levers which are associated with the respective needle channels along the length of the needle bed, the check levers each being pivotable by means of an electromagnet at the respective needle selection positions. In order to achieve a construction for the needle selection device which is compact, operationally reliable and has low maintenance requirements, the check levers are made of magnetically conductive material, permanent magnets are arranged on the carriage spaced in the direction of travel of the carriage and in alignment with the upper and lower lever arms of the check levers in such a way that the check levers are held by these permanent magnets in one or other of their two pivot positions, and the electromagnet is constructed and arranged in such a way that its pole shoes are arranged, at least on one lever arm side of the check levers, in the space between the poles of the corresponding permanent magnets.
