Abstract: A method and an apparatus for electroerosive material machining of a workpiece with an elongated tool electrode are described. The tool electrode is guided in an electrode guide, in which an oval void is embodied. The wire segment located in the void is exposed to a magnetic field, as a result of which the wire segment can be deflected laterally. The lateral deflection is converted into an axial motion of the wire segment located in the region of the workpiece, in order to create an optimal work gap between the workpiece and the free end part of the wire segment.

Abstract: In a textile machine, in particular in a knitting machine, with controlla working elements and an arrangement for selecting the working elements, the working elements are held in their initial position by a holding magnet and are selectively released from their initial position by an electromagnetic control system. In order to obtain a textile machine with a simple design, capable of being driven at high working speeds but in a reliable and safe manner, at least one holding magnet is rigidly fixed to the part of the textile machine that carries the working elements. A direct contact between the working elements and the moving control system is thus avoided, so that a contactless selection of the working elements is made possible.
