ABSTRACT:
An improved method of making a generally rectangular continuous electrode having a width to thickness ratio of at least 4:1 is disclosed comprising the steps of forming sheet metal into a first continuous trough shaped sheath, filling the trough with granular core materials and enclosing the trough. The core materials are restricted within the electrode by intermittently mechanically depressing a portion of at least one electrode wall which defines the width of the electrode, inwardly of the electrode.
