PCT No. PCT/EP84/00370 Sec. 371 Date Oct. 1, 1985 Sec. 102(e) Date Oct. 1, 1985 PCT Filed Nov. 24, 1984 PCT Pub. No. WO85/02631 PCT Pub. Date Jun. 20, 1985.There is described an apparatus for treating objects with a treatment fluid, more especially an etching or developing machine for the production of printed-circuit boards, wherein the nozzle stock comprising a plurality of nozzles is designed so as to be plate-like. The edges of the plate-like nozzle stock are tightly connected to the housing walls so that the treatment chamber, to which the treatment fluid is applied, is bounded by the nozzle stock in one direction. The nozzles can be fitted and possibly also rotated through the nozzle stock from the side that is directed away from the treatment chamber, so that an effortless exchanging or aligning of the nozzles is possible from outside the treatment chamber (FIG. 1).
