A sheet roll assembly for a copying machine in which a sheet reproduction of a sheet original is printed and processed, the sheet reproduction and original being conveyed to the outside of the machine after printing and processing. The sheet roll assembly is attached to the exterior of the machine proximate to and below the level at which a sheet emerges from the machine. The sheet roll assembly comprises a belt conveyor having an upper surface moving in a direction opposite to the direction of displacement of the emerging sheet and adapted to engage the leading edge of the sheet, and a curved plate mounted on the end of the upper surface of the belt conveyor for catching the leading edge of the sheet and causing the sheet to be spirally rolled against the curved plate, the sheet being continuously driven against the curved plate by the translation motion of the belt conveyor.
In a copying machine for printing and processing a sheet reproduction of a sheet original wherein said sheet original is conveyed to the outside of the machine after printing of said sheet reproduction and said sheet reproduction is conveyed to the outside of said machine after processing of said sheet reproduction, a sheet roll assembly comprising a frame fastened to the exterior of said machine proximate to and below the level at which one of said sheets emerges to the outside of said machine, a belt conveyor supported by said frame, said belt conveyor having an upper surface disposed in the path of the leading edge of said sheet and translated in a direction opposite to the direction of displacement of said sheet, and a curved plate fixedly mounted on said frame at the end of said upper surface of said belt conveyor for engagement with said sheet for causing said sheet to be spirally rolled.
