ABSTRACT:
A system for supplying treatment liquids to an electroplating drum rotatably mounted in trunnion bearings comprises at least two sets of ducts of different sizes opening into the electroplating drum and disposed in two series about a through bore of the bearing. An axially fluted inner surface of the through bore cooperates with a cylindrical outer surface of a removable cleaning tube to define one set of ducts. A liquid distribution valve allows treatment liquid to be supplied either to the two sets of ducts or to only one of the sets of ducts. Removal of the cleaning tube from the bearing allows overhaul of the one set of ducts.
