1,062,461. Inking apparatus. SOC. TECHNIQUE D'IMPRESSIONS FIDUCIAIRES. March 3, 1964 [Oct. 23, 1963], No. 8997/64. Heading B6C. An inking and wiping device for a multicolour intaglio printing machine comprises a plurality of inking rollers 6-9, a first wiping roller 10 which rotates without slipping in contact with the intaglio plates 4 on a cylinder 3 so as to compact ink in the bottom of the engravings and to remove a part of the excess ink from the engravings and from the plate surfaces, and a second roller 11 which rotates in the same direction as the roller 10 but at a slightly greater peripheral speed to remove further excess ink from the engravings and plate surfaces preparatory to a final wiping by a roller 12. The wiped plates 4, with the regulated volume of ink compacted into the engravings, print on sheets carried on the sectors 2 of an impression roller 1. The roller 10 is cleaned by rollers 16 and 17, the roller 17 itself being cleaned by brushes 19 provided in a solvent tank 20, and a doctor blade 18. The roller 11 may be reciprocated axially. The rollers 11 and 12 are cleaned by brushes 19 and blades 18. The roller 12 rotates in the opposite direction to the roller 11 and removes ink completely from the plate surfaces. The rollers 10-12 are adapted to avoid mixing of the ink colours. |
