Abstract
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 mounted for rotation on a support structure, a spiral rigid with, and extending along and around, the inner side wall of the barrel. Thus, the spiral acts, in use, as a spiral conveyor for moving the metal items from an inlet end of the barrel to its outlet end, and treating means such as a liquid solution for processing the metal items while being moved in the barrel.
Claims3
A continuous-cycle electroplating plant for plating loose metal items, the plant including a d.c. current supply and at least one processing unit comprising
- a barrel mounted for rotation on support structure,
- a spiral rigid with, and extending along and around, the inner sidewall of the barrel, thereby acting, in use, as a spiral conveyor for moving the metal items from an inlet end of the barrel to its outlet end,
- a plurality of longitudinal peripheral seats in communication with the barrel interior,
- pieces or rods of a plating metal accommodated in said seats and in electric contact with one pole of the said current supply, and
- a liquid electrolyte contained in the said barrel and in electric contact with the other pole of the said current supply.
