An improved photographic print stacking tray device includes a print tray concavely bowed transversely to the direction of travel and a central deflector. As the individual photographic prints are discharged from a conveying line onto the print tray, the central deflector pushes the central portion of each print downwardly while the side edge portions of each print are deflected upward by the print tray so that each print is bowed, thereby giving each print greater beam strength in the direction of travel.

Photographic print stacking tray

An automatic film conveying and packaging mechanism for conveying cut film lengths forwardly from a film cutter to a packaging envelope while maintaining continuous contact with the film lengths between a pair of opposed upper and lower conveyor assemblies and driving the lengths directly into the packaging envelope in stacked relation to each other with the trailing ends thereof positively disposed in substantial alignment with each other and in rearwardly spaced relation to the discharge end of the upper conveyor assembly.

Automatic film conveying and packing mechanism

A photographic print sorting, conveying and packing mechanism includes a main conveyor line and a plurality of branch conveyor lines with an initial feeding device which receives individual cut prints from a print cutter and feeds the prints into the main conveyor line which defines a main flow path. All of the conveyor lines include a plurality of driver rollers spaced apart less than the length of each cut photograph so that one roller will always be in contact with the prints to maintain positive driving contact with the prints at all times during their successive travel along the conveyor lines. The conveyor lines also include deflecting elements ahead of each roller to flatten momentarily the curl in each print and insure proper driving engagement between the rollers and the print. The branch conveyor lines have their entrances communicating with the flow path of the main conveyor line, the entrances being normally closed by diverting flippers which, when actuated, move into the main flow path to divert previously classified prints into the respective branch conveyor lines in response to classification indicia incorporated in the prints. Print collecting and ejecting stations are provided at the end of the respective conveyor lines, with a positive automatic ejection mechanism provided at the end of said main conveyor line for packing the collected prints into a packaging envelope positioned to receive the prints.
