摘要

The press has roll changers (1a-1d), and printing towers (2a, 2b) provided with printing units (6a-6c), and a folder unit provided with product displays. The roll changers and the printing towers are positioned on a common plane (8), where number of roll changers is larger than number of printing towers. Paper webs (9a, 9b) are turned around 90 degree between the printing towers and the folder unit. A paper web draw-in mechanism enables continuous feeding of the paper webs to the folding unit.
