Abstract: A machine for mounting a printing plate on a plate roll having an adhesively coated face. The machine includes a frame, means for rotatably mounting a plate roll on the frame in a selected position, a tilting framework swingably mounted on the frame and a pair of table sections mounted on the tilting framework on which the printing plate can be slideably mounted. A transparent grid plate is hingedly mounted on the tilting framework and can overlie the printing plate on the table sections. The printing plate can be advanced across the table section until the grid shows that the printing plate is properly aligned with the plate roll. Then a movable one of the table sections can be withdrawn and the printing plate can be advanced downwardly to bring a portion of the printing plate into engagement with the plate roll for attaching the printing plate to the plate roll. The plate roll can be turned to bring the rest of the printing plate into engagement with the adhesively coated face of the plate roll.
