Rotary offset printing press for first or second forme printing

摘要

The sheet (11) to be printed is turned in first or second forme printing by a turning drum (1) with co-operating sheet holder systems (9,10). Three sheet-guide cylinders (1,2,3) are positioned between the printing cylinders (4,5). A conveyor begins under the tangential point of the turning drum and the printing cylinder (4) in front of it for guiding and receiving the sheet to be turned. The first sheet guide cylinder is the turning drum.
