PRODUCTION OF METAL-FREE STRIPS ON METALLISED FOILS OF INSULATING MATERIALS

摘要

Improvements in devices for the manufacture of demetallized strips on sheets of metallic insulating material, especially for the manufacture of free edges on sheets of capacitor for electrical capacitors, in which the metallization of the sheet of metallic insulating material is attached to a pole of a voltage source and is passed through an electrical erosion electrode attached to the other pole of the voltage source, characterized in that said devices have one or more rotating, circular electrical erosion discs that are elastically pressed between two reversing rollers against metallization of the sheet of insulated material guided without support.
