Abstract
Apparatus for mounting flexographic printing plates by adhesive on the printing cylinders of a multi-cylinder printing machine has a rotatable hub for supporting each of the cylinders in turn, a platform for supporting each printing plate in a plane tangential to a cylinder on the hub, the platform being movable to cause the cylinder to roll along the plate so that adhesive on the plate or cylinder causes the plate to adhere to and wrap around the cylinder, and rack and pinion gearing between the rotatable hub and the movable platform. The hub has axial and radial abutments engageable with corresponding axial and radial abutments on the cylinders, and the platform has index pins engageable in apertures in the printing plates, the apertures in each plate being in the same position relative to the area of the plate corresponding to the total design to be printed, so that the printing media on the plates on the cylinders will be in register with one another for printing purposes when the cylinders are mounted on the printing machine with their axial and radial abutments in register with one another. The pins engageable in apertures in opposite ends of each printing plate are relativel…
