Abstract

As shown in the composite timing diagram, punched cards C and print documents PD leave their hoppers simultaneously. The cards travel at a constant speed past successive read stations R1, R2, R3, R4. The print documents move intermittently at a higher speed to successive print stations P1, P2, P3, P4 until arrested by corresponding stops at S1, S2, S3, S4. Thus, each document PD arrives at a print station, such as P1, before the card C arrives at the corresponding read station, such as R1. Thus, the lines of printing on the document PD are spaced further apart than the spacing between card columns.

Single Card Per Address Machine

As shown in the composite timing diagram, punched cards C and print documents PD leave their hoppers simultaneously. The cards travel at a constant speed past successive read stations R1, R2, R3, R4. The print documents move intermittently at a higher speed to successive print stations P1, P2, P3, P4 until arrested by corresponding stops at S1, S2, S3, S4. Thus, each document PD arrives at a print station, such as P1, before the card C arrives at the corresponding read station, such as R1. Thus, the lines of printing on the document PD are spaced further apart than the spacing between card columns.

As card C passes read station R1, the field mark FM associated with that station, (illustrated as digits 1, 6 and 7) is sensed. This sets up both the print unit and read unit to start reading and printing and simultaneously retracts stop S1 to permit document PD to move forward. One blank column X is provided on the card, following each field mark FM, to provide time for the print document to accelerate to printing velocity. Then feeding of the card and document is synchronized so that data read from the card is printed on the document until the next field mark FM (illustrated as digits 2, 6 and 7) is read. Read station R1 is then rendered inoperative, and the card C progresses to station R2. As soon as the second field mark FM (2, 6, 7) is sensed at station R2, stop S2 is retracted to permit document PD to resume motion.
