ABSTRACT:
A marking apparatus for printing indicia on products being transported along a conveyor. The moving products, such as cartons, are engaged by a printing roll with a drive rim that engages the surface of the article. As the printing roll turns, a printing segment carried on the roll comes into contact with the surface to print the indicia thereon. Ink is supplied to the printing segment by means of an ink supply roll mounted on a lever arm and which contains a supply of ink that is supplied to a porous ink-containing cylindrical surface. The lever arm is urged in one direction of rotation by a biasing device such as a compression spring to force the ink supply roll against an adjacent ink transfer roll with a predetermined force. The ink transfer roll has a cylindrical, elastomeric pad that receives ink from the ink supply roll and transfers it to the printing segment of the printing roll. A gear is connected between the printing roll and the transfer roll for turning the transfer roll surface at a speed differential relative to the surface speed of the marking surface so as to provide sliding contact between the ink transfer surface and the marking surface.
