ABSTRACT:
The plating apparatus (10) includes a pair of loop belts (20,21) rotating on two sets of pulleys, each set of pulleys including pulleys (11,12), to drive a strip (40) to be stripe plated past a translatingly movable electrolyte manifold (41) containing a series of electrolyte inlet and outlet slots (70,71) in its strip-facing surface. Electrolyte is sprayed from the inlet slots through apertures (24) in a back-up layer of at least one of the belts and through a slot (22) formed between belt segments. Vacuum or air pressure inlets (78,96) are provided at the ends of the manifold to prevent egress of electrolyte from the nip between the pairs of belts. One pulley of each set of pulleys is adjustable to tension the belt and an intermediate roller arrangement is included between each of the pulleys in each set to monitor the belt tension and provide sufficient frictional holding contact between the belts and the workpiece strip and desired sliding contact between the belts and the manifold surface.
