The invention relates to a process for the continuous preparation of photographic emulsions by a continuous flow process, in which a volume stream entering a pipe system flows successively through the various sections of this system corresponding to the individual stages of the process, such as the inlet points for introduction of the volume streams, mixing paths and ripening paths.

A cutting tool consists of circular, rotatably mounted upper and lower blades, the upper blade extending past the periphery of the cutting shoulder of the lower blade and bearing resiliently against it. The thickness of the cutting shoulder of the lower blade is less than the distance of the said extending of the upper blade, and the material hardness of the upper blade is greater than that of the lower blade.
