ABSTRACT:
An improved sheet feeding device is disclosed for feeding individual sheets separately from a stack into a high-speed press. The device is positioned over a portion of the stack, and includes flexible and moveable springs attached to a base portion, which is adjustably connected to the printer. The individual springs exert a downward pressure on the top sheet of the stack, preventing multiple sheets from being conveyed into the printer at one time.
