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 wide, 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 printing surface face-up.

Dependent claims

In a printing press having a rotating shaft for supporting a print cylinder;

at least a first and a second cam, spaced longitudinally on said shaft and extending radially outward thereof for controlling functions of said printing press upon rotation of said shaft,
said first cam including a first and a second slot means spaced radially outwardly of said shaft,
said second cam including a first and a second slot means spaced radially outwardly of said shaft;
and
means for securing each cam to rotate with said shaft, yet permitting selective circumferential adjustment of the position of each cam on said shaft independent of each other cam on said shaft;
said securing means including a radial disk mounted to rotate with said shaft and positioned on one side of said first cam facing away from said second cam,
first fastener means extending through said first slot means of both of said first and second cams for securing said first cam in a selected circumferential position to rotate with said disk,
second fastener means extending through said second slot means of both said first and second cams for securing said second cam in a selected circumferential position to rotate with said disk,
said second fastener means including a spacer extending through said second slot means of said first cam for maintaining said second cam in longitudinally spaced relation to said first cam on said shaft, and
both said first and second fastener means including means for loosening or tightening the same accessible from one side of said second cam facing away from said first cam.
