Abstract

Assemblies of collated film sections and related prints, each belonging to a customer, are fed seriatim into a tray at the right-hand side of a horizontal table in front of a seated attendant so that the attendant can remove an assembly with the right hand while the left-hand opens the corresponding customer pocket which is held in a position of readiness at the left-hand side of the table. The attendant can observe the collating operation by inspecting successive film frames while the frames move above an illuminated window below and in front of the web of photographic paper with exposed and developed prints thereon. The pockets are removed seriatim from a magazine and are transported to the left-hand side of the table where the rear panel of an oncoming pocket is held by suction to facilitate the task of opening the pocket by pulling the front panel away from the rear panel.
