Abstract

1,111,732. Printing-machines. OFFICINE MECCANICHE CIGARDI S.A. 21 Jan., 1966 [22 Jan., 1965], No. 2815/66. Heading B6C. Rotary machines; driving-mechanism.-Printing units U 1 , U 2 , U 3 connected by a synchronizing shaft 16, 17, 18 and clutches 19, 20 are driven by separate electric motors M 1 , M 2 , M 3 , supplied with D.C. by controllable sources A 1 , A 2 , A 3 . Transducers I 1 , I 2 , I 3 provide signals indicative of the current fed to each motor to the sources A. The motor M 1 acts as a pilot motor and a comparator circuit D 1 compares a reference potential T and a speed signal from a tachometer dynamo 21 connected to the motor, and applies an output difference signal to the source A 1 . The signal from I 1 is compared with those from I 2 , I 3 by units D 2 , D 3 controlling the sources A 2 , A 3 . The arrangement is such that where the power required to overcome the resistance R 1 , R 2 , R 3 of the units is P 1 , P 2 , P 3 , the actual output of the motors M 1 , M 2 , M 3 is controlled to be P 1 +x, P 2 , P 3 - x, where x represents a flow of energy always in the direction from the shaft part 16 to the part 18, to avoid inaccuracies resulting from torque reversal. The speed of the machine is controlled by the potential T.
