Abstract

1444945 Lithographic inking and damping system HARRIS CORP 4 Dec 1973 [22 Dec 1972] 56029/73 Heading B6C In order to simplify the cleaning of lithographic inking and dampening systems when the dampening forme roller may also carry ink received from the plate surface, the dampening forme roller, a driven rider roller, an ink forme roller and the ink distributor roller are maintained in that contact sequence for the transfer of washing solution. The ink forme rollers 17, 18 of the press are movable into non- printing position but stay in contact with the ink distributor roller 16; at the same time the resilient dampening forme roller 24 is tripped out of contact with plate cylinder 10 and is also removed from the hydrophilic vibrator roller 23 and the rest of the dampening train 11. The dampening forme roller 24 continues to rotate, however, by rolling in surface contact with a rider roller 25 driven via gearing from the main press drive, Fig. 2 (not shown). By movement of a lever handle (43), Fig. 4 (not shown), connected to a further cam and lever device, the ink forme roller 17 is pivoted into a second non-printing position where it contacts the rider roller 25, thus providing a path for cleaning liquid to the dampening forme roller 24. When the press is re-started, the forme roller 24 is synchronised to contact the plate cylinder 10 at a point where clamps 13 for the leading edge of the plate are arranged in a gap in the cylinder surface to allow for the roller 24 to be re-dampened by train 11 before printing.
