ABSTRACT:
An electroplating apparatus for plate-shaped workpieces, particularly printed circuit boards which are guided through an electrolytic solution in a horizontal path for the application of metal has a conveying arrangement comprising laterally arranged upper band drives and laterally arranged lower band drives whereby the workpieces are entrained in a friction-actuated fashion between a lower run of the upper band drive and an upper run of the lower band drive. In addition, a sealing wall is arranged between the upper and lower runs of each of the band drives to produce a sealing arrangement for a laterally exposed edge of the workpiece, which is engaged by a contacting mechanism for the cathodic contacting of the workpiece projecting through the band drives.
