Abstract
A printing machine for printing a continuous slip includes an angularly-movable lifter shaft disposed below a path of feed of the printing sheet, and a lifter fixedly mounted on the lifter shaft for angular movement therewith toward and away from the underside of the printing sheet. An urging device normally urges the lifter away from the printing sheet. A first tension applying device is operatively connected to the lifter shaft and is operable to angularly move the lifter shaft together with the lifter against the bias of the urging device so as to bring the lifter into engagement with the underside of the printing sheet to apply tension to the printing sheet when impression and blanket cylinders are spaced from each other, thereby preventing a slack developing on the printing sheet. A second tension applying device is operatively connected to the lifter shaft and is operable to angularly move the lifter shaft together with the lifter against the bias of the urging device so as to bring the lifter into engagement with the printing sheet to apply tension when a recess in the impression cylinder is brought into opposed relation to the blanket cylinder, thereby preventing a slack fr…
