Abstract: A device for a cell of an apparatus for wet processing of a planar workpiece, comprises a structure comprising first and second walls. The workpiece is movable in a central plane through a space between the first and second walls in a first direction (y). Apertures for introducing pressurised liquid between the first and second walls are on opposite sides of the central plane and facing the central plane. The apertures are distributed in the first direction (y) and in a second direction (x) transverse to the first direction (y). Discharge openings for the liquid to leave the space are on opposite sides, in the second direction (x), along the space in the first direction (y). The first and second walls form barriers to liquid flow from the space in a direction (z) perpendicular to the central plane. Channels through the walls are arranged to conduct liquid to respective one of the apertures.

Abstract: An electrode for an apparatus (1) for electrolytically treating a workpiece (3), the apparatus (1) being of a type arranged to convey the workpiece (3) with a surface to be treated past and directed towards a surface of the electrode, is divided into segments (23a-e) at at least this surface of the electrode. The segments (23a-e) are arranged next to each other in a first direction (x). Adjacent segments (23a-e) are separated from each other along respective segment edges (24a-f) such as to allow adjacent segments (23a-e) to be maintained at different respective voltages. The segment edges (24a-f) extend at least partly in a second direction (y) from a common value (y0) of a co-ordinate in the second direction (y) to an edge (25,26) of at least an electrically conducting part of the electrode surface, the second direction (y) being transverse to the first direction (x) and corresponding to a direction of movement of the workpiece, in use.

Abstract: The device in accordance with the invention and the method serve to treat flat and flexible work pieces (1) with a fluid, preferably in electroplating plants and etching facilities. The device and the method permit to place foil-type work pieces (1) in particular in such a manner into the fluid, a wet-chemical or electrochemical processing fluid for example, that the work pieces (1) will not deform or hit the side walls of a processing tank (3) or other built-in components. For this purpose, the processing tank (3) is assigned a protective carrier (5) into which the work pieces (1) are lowered, said carrier (5) being in a largely empty condition. For treatment, the protective carrier (5) is for example lowered into a tank (3) which is filled with processing fluid, said processing fluid flowing into the protective carrier (5). Means are provided on the protective carrier (5) by means of which the processing fluid is allowed to controlledly flow into the protective carrier (5).
