Abstract

The invention relates to a method and a device for producing a piezoelectric actuator component, which has a layer structure of several layers of an active material, in particular a piezoelectric ceramic, and conductive electrodes arranged respectively between the layers of an active material. For this purpose, a plurality of in particular parallel, spaced sections of a wire are wound on a coil form (8) as windings (5), wherein the windings (5) are disconnected after being fastened. In this way, several parallel sections of the wire (6) of various windings (5) form the electrode. It has been show that, thanks to the method according to the invention, the parallel wires (6) can be produced in a surprisingly simple manner by first fabricating said parallel wires in the form of a plurality of windings of a single wire (6) as a winding on the coil form (8) and then separating said parallel wires along the circumference of the layer surface according to the desired dimensions.
