ABSTRACT:
Ink is supplied to an ink duct in a rotary printing press from an ink cartridge. The cartridge receives a piston which can be pushed into the cartridge from one end to force ink out of the discharge end of the cartridge. This piston is moved through the cartridge by a helical gear in the form of a rotatable spindle driven by an electric motor.
