Abstract

The present invention overcomes the drawbacks and limitations described above by providing a paddle assembly having a paddle that moves in a bidirectional fashion for agitating solution in a container of a plating cell. A follower is coupled to the paddle. The follower engages a rotatable cam and is propelled along the cam as the cam rotates. A drive mechanism rotates the cam.
