摘要： @ A continuous-cycle electroplating plant for a plating loose metal items, the plant including a multiplicity of sequentially arranged processing units which comprise at least one pre-treating unit, one or more electroplating units and at least one passivating or coloring unit. Each processing unit comprises a barrel (2) mounted for rotation on a support structure (15), a spiral (8) rigid with, and extending along and around, the inner side wall of the barrel. Thus, the spiral (8) acts, in use, as a spiral conveyor for moving the metal items from an inlet end (3) of the barrel (2) to its outlet end (4), and treating means such as a liquid solution for processing the metal items while being moved in the barrel (2).
