ELEKTROLYTKONDENSATOR OG FREMGANGSMAADE TIL FREMSTILLING AF EN ELEKTROLYTKONDENSATOR

摘要

All the layers of the anode foil of an electrolytic capacitor roll (5) are cold welded to a piece of tabbing (8) using radiussed weld tooling (10, 12, 13) which bends the foil layers in the course of the welding operation so as to enable a good weld to be effected. The cathode foil layers are welded to their piece of tabbing in the same way. Optionally the roll may be partially flattened at the time the welds are made.
