<p>The column has a printing-block cylinder working with a bottom inking mechanism. The latter has a friction roller coupling two application rollers, while a top inking mechanism incorporates an ink-feed train. A screen roller (21) and chamber-type duct (22) work with one of the rollers of the bottom mechanism (6), from which the top one (7) is separate. The printing cylinder (2) can form an application cylinder with rubber blanket, while the offset cylinder (4) is equipped with a printing block.</p> |
