    摘要： A web-fed, multicolor, offset perfecting printing press having a series of printing units (P) for printing different color images on both sides of a continuous web (W) of paper, each printing unit having a combination of a plate cylinder (PC) and a blanket cylinder (BC) on one side of the web, and another such combination on the other side. Each plate cylinder is split into a pair of halves (PC 1 and PC 2 ) for printing a pair of images in juxtaposition transversely of the web, the pair of halves of the plate cylinder being capable of independent displacement both axially and circumferentially of the plate cylinder. For precise registration of the different color images printed by the different printing units (P) on the web, there are provided a pair of axial adjustments (3 and 3', or 3a and 3a') coupled to opposite ends of each plate cylinder (PC) for causing axial displacement of the respective plate cylinder halves with a view to fine image positioning transversely of the web, and a circumferential adjustment (4 or 4a) for causing circumferential displacement of either half of each plate cylinder with a view to fine image positioning longitudinally of the web. A separate drive mechanism (1) drives each combination of one plate cylinder and one blanket cylinder of each printing unit, so that each drive mechanism serves the additional purpose of positioning the images longitudinally of the web preparatory to fine positioning.

    摘要： Die Erfindung betrifft eine Rotationsdruckmaschine mit wenigstens einem Druckwerk, welches einen Plattenzylinder (12) aufweist, der lösbar auf der ihn tragenden Welle (10) anbringbar ist, wobei Plattenzylinder und Welle mit Mitteln versehen sind, die es ermöglichen, den Plattenzylinder sowohl axial als auch in Umfangsrichtung zur Welle und damit zum zu bedruckenden Objekt auszurichten und in der ausgerichteten Position an der Welle zu befestigten, dadurch gekennzeichnet, daß der Plattenzylinder (12) mit Positioniermitteln (18) für die Festlegung seiner Position in Umfangsrichtung und in axialer Richtung versehen ist, die mit der Welle zugeordneten Anschlagmitteln zusammenwirken. Die Anschlagmittel sind axial verstellbar in einem von der Welle getragenen Kragen (30) angeordnet, der mit Ausnehmungen versehen ist, in die die Positioniermittel (16,18) eingreifen, um darin mit den Anschlägen in Berührung zu kommen.
