Abstract:
A web-fed offset lithographic press for printing multicolor images on a continuous web of paper or like material traveling through a series of printing units, at least one of the printing units comprising:(a) a plate cylinder split into a pair of halves for concurrently printing on one side of the web a pair of images in juxtaposition transversely thereof, the pair of halves of the plate cylinder being capable of independent displacement both axially and circumferentially of the plate cylinder; (b) a blanket cylinder in rolling contact with the plate cylinder, the blanket cylinder being different in diameter from the plate cylinder; (c) a first and a second drive motor capable of synchronous operation; (d) a first drive linkage drivingly coupling the first drive motor to one of the plate cylinder halves; and (e) a second drive linkage drivingly coupling the second drive motor to the other of the plate cylinder halves and to the blanket cylinder, the second drive linkage transmitting power from the second drive motor first to a smaller diameter one, then to a larger diameter one, of said other plate cylinder half and the blanket cylinder.
