A change-over device comprising several connecting tubes is arranged before the coating station in order that during the coating of photographic silver halide emulsions the coating operation need not be interrupted when changing from one emulsion type to the other thus allowing direct coating of one of the emulsions which are fed from the supply containers while the remaining emulsions are recycled into the emulsion line by means of a pressure regulating valve. The outlet of an emulsion is effected by a rotational and lifting movement of the changeover piston.
