AbstractA feed system for large copy sheets to feed such sheets through a copying machine, such as a white print, blue print or other copying machine, a computer printing machine, a pen plotter of other vector plotter, or raster plotter, or a printing machine. A supply roll is provided with copy sheets wound on the supply roll in an interleaved or overlapping array. A pair of support rollers form a cradle for freely supporting the supply roll, with at least one of the support rollers being driven. A printing roller grasps a copy sheet as the sheet is fed from the supply roll. A sensor stops the driven support roller and, in turn, the supply roll at a given time in a predetermined cycle whereby the printing roller can pull the fed sheet away from the supply roll and away from a succeeding overlapped sheet interleaved with the fed sheet.
