Machine for development of exposed pictures

In a machine for developing picture material of the type wherein a cylindrical member is rotatably mounted on a drive shaft, means are provided to produce a liquid film on the outer surface of the cylindrical member, and further means are provided for positioning the picture material in contacting engagement with the liquid film on the outer surface of the cylindrical member, the improvement comprising an elongated tank, partition means to subdivide said tank in the longitudinal direction into a plurality of receptacles for different process liquids, a cylindrical member partially immersed in the liquid in each tank and rotatably mounted on a driven shaft about a substantially horizontal axis so that rotation of said cylindrical member produces a liquid film on the outer surface thereof, said cylindrical members being coaxially aligned in a continuous row, and conveying means for conveying the picture material into contacting engagement with said liquid film surface on said cylindrical members comprising two driven elongated conveyor shafts rotatably mounted adjacent the outer surface of said cylindrical members with their longitudinal axes of rotation in parallel with the rotational axis of said cylindrical member, picture material mounting means on said conveyor shafts to mount said picture material in continuous strip form so that said picture material can be transferred between said mounting means with one surface thereof in contacting engagement with said liquid film surface on a cylindrical member, and said mounting means being movable axially along said conveyor shafts so that said strip-form picture material can be transferred from one cylindrical member to another to successively treat it with said different process liquids in said receptacles.
