ABSTRACT:
A pair of parallel blanket rollers have their ends received in respective eccentrics themselves received in respective spaced-apart holes in a support frame. A pair of plate cylinders each tangentially contacting a respective blanket cylinder are similarly received in respective eccentrics also received in respective holes in the machine support. Each of the holes receiving an eccentric for a respective cylinder is of greater diameter than the respective cylinder so that the cylinders can be mounted in the machine frame by slipping them axially through these holes. A web to be printed is passed between the two blanket cylinders for simultaneous printing on both sides. The plate cylinder to one side of the web being printed and the blanket cylinder to the opposite side lie in one plane and the other two cylinders lie in another plane parallel to but spaced horizontally from the first-mentioned plane. Rotation of the eccentrics, at least the inner ones of which may be formed of two parts, allows radial adjustment of the various cylinders relative to each other.
