Edge protector for electrolytic electrode, and spreader bar

An edge protector for an electrolysis electrode comprising:

• an inner jaw disposed in a longitudinal direction of said edge protector;
• an outer jaw disposed in a longitudinal direction of said edge protector;
• and
• a hollowed spreader bar, said bar having a hollowness disposed in a longitudinal direction;
• said hollowed spreader bar capable of ready removable insertion into, and detachment from, said edge protector.

An edge protector of an electrolysis electrode for producing an electrolytic copper product comprising:

• an inner jaw disposed in a longitudinal direction of said edge protector at a first end;
• an outer jaw in a surface of said edge protector opposed to a surface containing said inner jaw at a second end;
• a first surface extending along a first side of said edge protector;
• a second surface extending along a second side of said edge protector;
• said first and second surfaces converging toward each other in a direction from said outer jaw toward said inner jaw, to reduce an amount of material in locations between said first and second surfaces sufficiently to reduce thermal stresses in said locations;
• a spreader bar;
• means for permitting insertion of at least a portion of said spreader bar into said outer jaw without expansion thereof;
• and
• means for forcibly urging a portion of said spreader bar into contact with said outer jaw, whereby expansion of said outer jaw, and consequent urging of said inner jaw in a clamping direction is performed;
• said first end further comprising opposing top and bottom portions of said inner jaw, wherein each said top and said bottom portion is angled upward from said first surface of said edge protector to said second surface, at an angle which is less than about twenty degrees is formed at a first end of said edge protector, at each said opposing top and bottom portion of said inner jaw, from each said first surface to each said second surface of each said portion from the center portion of the edge protector outward.
