Abstract: 1,152,553. Rotary printing apparatus. G. RITZERFELD. 28 April, 1967 [29 April, 1966; 22 July, 1966], No. 19703/67. Heading B6C. A rotary duplicator for alternatively printing whole pages or one or more lines on a copy sheet, and for producing coded recordings on said copy sheet which correspond to at least part of a text printed, comprises a rotary cylinder to which is attachable a master printing sheet for producing a copy sheet, means for marking a carrier with a record of at least part of the text printed on the copy sheet, scanning means for scanning the marked carrier, the record scanned creating a corresponding signal, means for transmitting the signal to a marking device for correspondingly marking the copy sheet, and means for transporting the carrier after each scanning operation a predetermined distance controlled by the duplicator. Fig. 1 shows the production of a printing master sheet original 1 on a writing device 2 and also the simultaneous production of a record carrier 3 on a punching device 4 coupled electrically to the device 2. The device 4 may also be in the form of a writing device. The printing cylinder 6 with the original 1 and the carrier 3 may perform a respective line step, synchronously with the aid of a magnetic clutch. A brush set 10 may read the information on the carrier 3 either synchronously with the printing of corresponding information by the cylinder 6 or at a time spaced by one or more working revolutions of the cylnder 6. By way of cables 11 and 12 the values read by the brush set 10 from the record carrier 3 are transmitted to a card punch 13 and to a checking station 14. When the card enters the punch 13, which occurs after the card has been printed, it is punched with the values fed to the punch. After the card 5 has left the punch 13 the values punched in it are read by a checking brush set 15 and transmitted by means of the cable 16 to the checking station 14. If the values transmitted by the set 10 and by the checking set 15 to the checking station 14 do not agree, the machine is automatically switched off. Fig. 10 illustrates diagrammatically an entire process from the making of an original 1 on a writing device 123 with the simultaneous production of a punched tape 124 on a punching device 126 connected by an electric cable 125 to the writing device 123, to the delivery of the printed, punched card 5. By means of a cable 127, the values read off the punched tape 124 by a reading device 128 are fed through a decoder 128a to a card punch 129; which on the entry of the card S, that is to say after the printing operation, punches these values in the card 5. The printing cylinder 6 and the card punch 129 are driven synchronously by a motor 130. Fig. 12 illustrates diagrammatically an entire process from the production of the original 1, on a writing device 123 and the simultaneous production of a record carrier 170 on a punching device 171, coupled electrically to the device 123, to the delivery of the printed, punched card 5. The device 171 may also be constructed as a writing device, in order to be able to make recordings for optical or magnetic reading. In Fig. 12 the reading is effected by brush sets 172, 173 within one revolution of the cylinder 6 or at times offset by one or more working revolutions of the cylinder 6. Through cables 174, 175, the values read off the carrier 170 by the brush sets 172, 173, are received by a distributer 176 and fed through cables 177, 178 to the punch 129 and to a checking station 179. When the card 5 enters the punch 129, which takes place after the card has been printed, it is punched with the values fed in. After the card 5 leaves the punch 129 the values punched in are read by a checking brush set 180 and fed through a cable 181 to the checking station 179. Should the values fed to the station 179 by the brush sets 172, 173 and by the brush set 180 not coincide, the machine is automatically switched off.
