Abstract
Abstract Apparatus for making prints of exposed and developed film frames on discrete sheets of photographic paper and for developing the sheets has a copying station for successive exposed and developed film frames and a printing station where a discrete sheet of photographic paper receives an image of the frame at the copying station. A platform at the printing station carries a turntable which can change (when necessary) the orientation of a sheet, e.g., through 90°, to thus properly position a larger or smaller sheet for reception of the image. The turntable can receive sheets which are severed from different webs of unexposed photographic material, and each such web has a different width. The turntable can attract a sheet by suction during turning and/or during exposure. Such turntable can cooperate with one or more conveyors to maintain a sheet at the printing station in a predetermined plane during imaging of a film frame.
