Abstract

1. Process for producing a piece having at least one dielectric separating layer from a ferromagnetic blank (30), a recess (31) being worked into the blank, which recess is so formed that the individual parts of the blank are joined together by at least one border-bridge (32), whereupon a non-ferromagnetic material (34) is introduced into the recess and the blank is subjected to a material-removing operation so that the ferromagnetic parts are joined together only through non-ferromagnetic material, characterised in that the blank (30) is heated in the form of a block to a temperature at which it is plastically deformable and plastic deformation of the blank is carried to form the said recess (31), and that after introduction of the non-ferromagnetic material (34) into the recess, the blank together with the non-ferromagnetic material introduced is compressed before the material-removing operation is carried out.
