Abstract

831,577. Inking-apparatus. DE LA RUE CO. Ltd., [formerly DE LA RUE CO. Ltd., T.]. April 3, 1958 [Aug. 7, 1957], No. 24946/57. Class 100(2) In a rotary printing machine, an inking unit comprises a positively driven fountain roller (3) in communication with a supply of ink, a plate cylinder (1) positively driven in the same direction and carrying on one end a cam consisting of a raised portion (6), an intermediate portion (7), and a trough portion (8), a cam roller (23) adapted to contact said cam, an inking roller (2) freely journalled in bearings (10) in pivoted arms (11), and means for moving the arms in response to movement of the cam roller, whereby the inking roller dwells alternately on and is driven by the fountain roller and the plate cylinder, and runs freely between its periods of contact. A shaft 15 carries lugs 14 and is rocked through a link 20 by a lever 18 carrying the roller 23 and pivoted at 19. The lever 18 and link 20 are connected by an eccentric pin 21 adjustable by a handle 22 to keep the roller 2 clear of the cylinder 1 when desired. The lugs 14 are connected to the arms 11 through spring-controlled eye bolts 13 having handwheels 16 to adjust the pressure between the roller 2 and the plate, while pressure between the rollers 2, 3 is controlled by adjustable tension springs 17. The cam portions 6, 7, 8 are connected by sloping riser members 9 and are made in segments so as to be changeable.
