Abstract
A flexible thermoplastic printing plate is mounted on a plate cylinder having a given curvature. In its unstressed condition, the printing plate has substantially the same curvature between its ends as the cylinder. The printing plate has laterally extending hooks at its ends. A stationary laterally extending projection on the cylinder engages the hook at one end of the plate. A movable laterally extending projection on the cylinder engages the hook at the other end of the plate; the movable projection is spring-loaded so as to tension the plate longitudinally on the cylinder. A plurality of gussets are formed in each hook and a plurality of recesses for receiving the respective gussets are formed in each projection. Opposite sides of two recesses in each projection are precisely located relative to the cylinder. The opposite sides of the two recesses receive the respective gussets with a close fit to index the plate laterally on the cylinder, while the sides of the remaining recesses receive their respective gussets with a sufficiently loose fit so as not to interfere with such indexing.
