Abstract

869,904. Printing-machines; inking apparatus. TIMSONS Ltd. July 29, 1959 [Aug. 18, 1958], No. 26473/58. Class 100(2) In a rotary printing machine of the kind adapted to print on a web which passes between co-operating cylinders and having ink-applicator means and heating devices at a drying zone for drying the printed web, the ink applicator means are movable into and out of operative position dependent on the speed of the machine. The plate cylinder 1 is inked by an inking unit 11 having a duct roller 12, an inking drum 14, distributing rollers 17, 18, a ductor roller 19, and forme rollers 15, 16, all carried by a common frame F. The frame F is longitudinally movable on rollers 21 into and out of the operative position shown. The frame F is actuated by a pin 25 on the frame engaging an eccentric 20 rotated by a chain wheel, not shown, engaging a chain 26 connected to arms 27a, 27b of a lever 27. The lever has a further arm 27c connected to a piston rod 37 of a pneumatic actuator 35 supplied with compressed air through a solenoidcontrolled valve 34. A solenoid 34 for actuating the valve 34 is in circuit with a switch 32 operated by a rotary cam 31 driven in synchronism with the motor 6 driving the machine, such that the inking unit is moved into operative position when the machine attains a predetermined speed during starting and is likewise tripped during slowing down of the machine. An inking unit may be moved by a rack and pinion in place of the eccentric. The impression cylinder 2 is actuated towards and away from the plate cylinder 1 by a pneumatic actuator 42 which rocks a lever 40 carrying eccentric bearings for the cylinder 2. The actuator 42 is controlled by a solenoidactuated valve 41 having a solenoid in circuit with the switch 32. Alternatively, the web may be printed on one or both sides by one or a pair of offset cylinders. Specification 869,903 is referred to.
