A process and apparatus are disclosed for controlling the flow of operations in electroplating plants with horizontal throughflow in which the parts to be electroplated, in particular plate-shaped parts, pass through the plant in succession and are electroplated by means of currents applied by anodes. In order to prevent undesirable, increased precipitation on the front faces or edges of parts to be electroplated which follow each other at undesirable distances apart, or at least to reduce this precipitation to an acceptable level, the position of the parts which pass through the plant in succession and/or the distances between these parts are detected and the application of the electroplating currents is controlled as a function of these positions and/or distances by switching the anodes on and off, in such a manner that the flux density is approximately the same in all regions of the parts.
A method for controlling the work cycle of horizontal, continuously running, electroplating plants, in which parts to be electroplated pass through the plant one after another and are electroplated by means of currents emanating from anodes, characterized by the fact that the positions of the parts (1) passing through the plant one after another and/or the intervals (a.sub.1, a.sub.2) between these parts is detected, and that the delivery of the electroplating current is so adjusted by the switching on and off of the anodes (4, 7) adapted to these positions and/or intervals, that the flux density on all regions of the parts (1) is roughly equal.
