Plant for the treatment of objects by means of a treatment liquid, particularly an etching or developing machine for manufacturing printed circuit boards, wherein the nozzle rod comprising a plurality of nozzles is shaped like a plate. The edges of the plate-like nozzle rod are secured very close to the casing walls so that the treatment chamber impinged by the treatment liquid is limited in one direction by the nozzle rod. The nozzles may be mounted and, optionally, turned through the nozzle rod from the side opposite to the treatment chamber so as to enable an easy replacement or reorientation of the nozzles from outside the treatment chamber. |
