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.

A method of making a generally rectangular continuous electrode, having a width to thickness ratio of at least 4:1, comprising the steps of:
- forming sheet metal into a first continuous trough-shaped sheath,
- filling the trough-shaped sheath with granular electrode core materials,
- enclosing the sheath,
- intermittently mechanically depressing a portion of at least one electrode wall which defines the width of the electrode, inwardly toward and spaced apart from the opposing wall of the electrode along the length of the electrode to immobilizedly restrict the electrode core materials within the electrode, and then
- coiling the electrode.
A method as set forth in cliam 1 wherein the sheath is enclosed by mechanically binding the edge portions of the trough with one another along the length of the electrode.
A generally rectangular, continuous electrode having a width to thickness ratio of at least 4:1 comprising:
- a continuous trough-shaped, enclosed sheath of sheet metal,
- granular core materials immobilizedly disposed within the trough-shaped sheath, and
- intermittent mechanical depessions formed subsequently to the filling and the enclosing of the electrode in at least one wall of the electrode which defines the width of the electrode, along the length thereof, directed toward and spaced apart from the opposing wall of the electrode restricting the core materials into individual compartments with the electrode, the electrode being coiled.
A generally rectangular, continuous electrode having a width to thickness ratio of at least 4:1 comprising:
- a continuous trough-shaped sheath of sheet metal,
- granular core materials immobilizedly disposed within the trough-shaped sheath,
- a continuous strip of sheet metal closing the trough with the edges of strip, and
- intermittent mechanical depressions formed subsequently to the filling and the enclosing of the electrode in at least one wall of the electrode, which defines the width of the electrode, along the length thereof directed toward and spaced apart from the opposing wall of the electrode restricting the electrode core materials into individual compartments within the electrode, the electrode being coiled.
