Abstract
A conducting roller assembly for an electroplating apparatus includes two conducting rollers arranged one above another so as to clamp and move a plate-shaped workpiece therebetween. The rollers are disposed intimately over one of two conducting members, and under the other one of the members. Each of the members is connected to two opposite sides of the respective one of the rollers by means of two horizontal rows of equidistant conducting posts. Each of the posts has one end that is fixed to and that is in electrical connection with a respective one of the members, and another end that is biased to contact the respective one of the rollers so as to establish an electrical connection between the respective one of the members and the respective one of the rollers.
