ABSTRACT:
Disclosed in a capping board for use to support hanging legs of anodes and cathodes within adjacent electrolytic cells. This capping board has a main body having a bottom surface shaped to fit onto upper edges of the adjacent cells, and a top surface. A first set of spaced part insulating blocks project from the top surface. This first set of blocks extends in line all over the length of the capping board on one side of the main body. A second set of spaced part insulating blocks also projects from the top surface. This second set of blocks also extends in line all over the length of the capping board at a given lateral distance from the first set of blocks. Thus, the two sets of blocks form two rows that together define a central path on the top surface. Each of the blocks has a recess forming an upwardly and laterally opening compartment to receive and support one of the hanging legs of the anodes and cathodes. Advantageously, a plurality of separating walls project upwardly from the top surface of the main body so as to extend transversally across the central path and dividing this central path into a plurality of separate segments in which separate contact bars may respectively be positioned. Due to such a division of the contact bars into separate segments, any short circuit that occurs by accident is no more “transferred” to all the electrodes of the cells. It is actually transmitted only to the few electrodes in contact with the segment(s) to which is connected the electrode that is at the origin of the trouble.
