Abstract
A photosetting apparatus is provided having a cylindrical bed into which sheet-shaped photo-material is transported and placed against an inside thereof. The cylindrical bed has a longitudinal axis positioned in spaced relation from an inside surface of the bed and such that the cylindrical bed inside surface curves in cylindrical fashion partially around the longitudinal axis. An exposure optics exposes the sheet-shaped photo-material, the exposure optics being displaceable along the longitudinal axis of the cylindrical bed. A conveyor mechanism conveys the photo-material parallel to and in a direction along the longitudinal axis of the cylindrical bed into a position adjacent the inside surface of the bed. A guide mechanism having movable elements presses the photo-material against the inside surface of the cylindrical bed from inside.
