1451693 Inking and damping apparatus POLYGRAPH LEIPZIG KOMBINATE FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 10 Oct 1974 [24 Oct 1973] 43889/74 Heading B6C A rotary offset printing machine has a plate cylinder 14 inked by train 1, 2, 3, 4, 5, 6, 4, 6, 7a, and damped by train 8, 9, 10, 11, 12, 13a, the rollers 13a, 7a being trippable to positions 13b, 7b, the tripping of rollers 13a being independent of the position of roller 7a. The two trains are interconnected by roller 15a which can be tripped to position 15b to interrupt this interconnection. Rollers 13a, 7a and 15a may be spring-urged to the tripped position (Fig. 2, not shown), and urged to their operative position against the springs by electromagnetic pushers under the control of a circuit (Fig. 3, not shown) to enable damping to be performed before inking and before the interconnection is made. |
