Abstract

Procedure for the manufacture of demetallized strips on sheets of metallic insulating material, especially free edges on sheets of capacitors for electric capacitors, by means of a locally limited destruction of the metallization by means of an electric current, in which the metallization of the sheet of Metallized insulating material is passed through an electrical erosion electrode and is maintained at a potential different from that of this electrical erosion electrode, characterized in that a relatively small alternating voltage is applied at a relatively high frequency between a metallization and the erosion electrode, because the electrical erosion electrode and metallization do not press together, because the electrical erosion electrode moves and therefore the part of the erosion electrode that comes into contact with the metallization is constantly removed.
