<p>The invention concerns an apparatus for the locating of flexible printing plates (27) on printing cilinders (5). The flexible printing plates (27) to be located on a printing cilinder (5) each comprise two marks (16), and when those two marks are correctly located, the printing plates are positioned correctly. Two light sources (13) are provided each emitting a narrow beam towards the printing plate, so that two markings are projected on the locations of the marks of the printing plate to be fixed. Thus the location of the printing plate can easily take place. Further the projected markings are used to measure a length of adhesive foil such that said length fits exactly on the circumference of the printing cilinder.</p> |
