ABSTRACT:
A friction sheet feeding machine having (i) a tray for holding a stack of sheets, (ii) a driven friction feed roller for contacting a downward facing major surface of a lowermost sheet in a stack retained within the tray and pulling the lowermost sheet in a machine direction from underneath the stack, (iii) a reversibly driven friction retard roller vertically spaced in parallel relationship above the friction feed roller for contacting a leading edge and any exposed upward facing major surface of a sheet immediately overly the lowermost sheet so as to retard advancement of the overlying sheet, (iv) a first motor operably connected to the friction feed roller for driving the friction feed roller, and (v) a second motor operably connected to the friction retard roller for driving the friction retard roller, wherein the first and second motors are operably associated such that the second motor is operational only when the first motor is operated.
