ABSTRACT:
Apparatus for straightening and orientating the deformed nipples of an anode employs framework through which each anode suspended by its anode rod is passed. A hollow casing with openings for receiving the nipples is raised relative to the framework to locate the nipples in the openings. A yoke of the anode is supported by pressure-pieces driven by self-locking spindle drives to engage the yoke from the outside and by support members engaging the yoke from the underside. The casing carries mechanisms each composed of piston and cylinder units with the piston rods and cylinders interconnected by yokes. One of these yokes has recesses for applying force to a central nipple and the other of these yokes carries a force-applying element with a socket for receiving the outermost nipples. The yokes and force applying elements are guided within the casing and serve to bend the nipples back into the desired orientation. Stops serve to control and limit the displacement of the piston and cylinder units.
