Abstract: Apparatus for collating prints and related sections of developed photographic customer films in a processing laboratory has a first conveyor whose receptacles advance stepwise into register with discharge ends of feeding devices for film sections and prints, and a packing unit with a second conveyor which advances empty containers past an assembly station where the containers receive assemblies of film sections and related prints in response to forward strokes of a reciprocable pusher. The second conveyor advances successive loaded containers past a closing device and a labelling device and thereupon into a receiving device. A computer receives signals from the severing mechanisms of the two feeding devices and from a reader which decodes information on envelopes used by customers or dealers to deliver or send exposed customer films to the laboratory.
