ABSTRACT:
In order to fix two plates (3, 4) onto the cylinder formed by a sleeve (1) or by a plate cylinder of the intaglio printing machine, two axial grooves (2) are formed on the cylinder such that the plane of one of the lateral faces of each groove (2) forms an angle with the axis of the cylinder. A strip (5, 6), whose face adjacent to the end of the plate is perpendicular to said plate, is welded onto the concave face of the two ends of each plate (3, 4). The edge of each plate (3, 4) projecting beyond the corresponding strip (5, 6) is then cut off such that the edge of the plate forms a continuous surface with the face of the strip, and such that the sum of the lengths of the plates equals the length of the periphery of the cylinder. The plates are then arranged on the cylinder (1) by introducing the neighboring strips (5, 6) into a groove (2) and the free space in the groove is completed by a wedge-shaped strip (7) in order to tension the plates and obtain an edge-to-edge join.
