ABSTRACT:
The basic press structure includes a printing couple consisting of a lower printing cylinder, having a single work area, and a large printing cylinder, having an effective diameter which is a whole multiple, greater than one, of the effective diameter of the lower printing cylinder, and has a number (equal to the whole multiple) of work areas, in each of which one of a variety of the especially constructed removable and interchangeable segments may be mounted. One of a variety of different printing surfaces may be carried in each of the various work areas on the cylinders of the printing couple, in a wide range of combinations. The printing couple is mounted in a frame structure constructed so as to provide a plurality of module mounting positions, at each of which one of a variety of printing modules may be mounted in cooperative relationship with the large printing cylinder. The press includes feeder means on one side of the printing couple and delivery means on the other side, and selectively controllable means are available for causing sheets to be fed to every revolution, or to other than every revolution, of the lower printing cylinder, for causing a sheet to be carried through the bite of the printing couple, once or more than once, as it passes through the press and for causing the sheets to be delivered with a selected printed surface face-up.
