摘要

Below is a loose leaf printing plant (1000; 1000 *) consisting of at least two printing units (200; 200.1; 200.2; 200.1 *).200.2. * one by one, each printing unit (200; 200.1; 200.2; 200.1 *) is adjusted.200.2. * used for printing when the two sides of the paper are the same, and includes two printing cylinders (105, 106) that cooperate with each other and form a printing line, each cylinder collecting ink patterns of at least two plate cylinders (15a, 15b, 16a, 16b). 2. The positions of the two printing cylinders (105, 106) overlap each other, and each paper moves horizontally (200) through each printing unit;Page: 1200.2 *) from the first side above the printing line (201a; 201a *) to the second side (201B) of the second side (201B; 201B *), there are at least two work order transfer items (110, 120) under the printing line, 95. Downstream of the first printing line (200.1200.1 *) and upstream of the second printing line (200.2200.2 *) for at least two printing units (200.1200.2200.1 *),Page: 1
