Abstract

An improved photographic print stacking device includes a print slide concavely bowed transversely to the direction of travel proximate a discharge end of a conveying line, and a pair of drive rollers. Individual photographic prints are conveyed on the conveying line onto the concavely bowed print slide. The drive rollers engage and push the central portion of each print downwardly against the central portion of the print slide, while the slide edge portions of each print are deflected upwardly by the side edges of of print slide so that each print is bowed, thereby giving each print greater beam strength in the direction of travel.
