Abstract
The printing machine is composed of an indirectly printing printing unit (A), and a sheet transport device (B), composed solely of drums (18, 19, 20, 22, 23, 24), and of a following intaglio printing unit (C). The indirectly printing printing unit (A) has two interacting blanket cylinders (3, 5), each of which is inked with several colors by several plate cylinders (12, 15; 7, 10). The sheets are passed onto one of the blanket cylinders (3) from a carry-over drum (2) and, after passing through the nip between two blanket cylinders (3, 5), thereby being printed on both sides, are taken over by a transfer drum (18) of the sheet transport device. The circumferential region which is located between the carry-over drum (2) and transfer drum (8) and over which the sheet passes extends over at most 180.degree., preferably less than 150.degree., so that that free circumferential region of this blanket cylinder not covered by the sheet is available for accommodating several plate cylinders.
