ABSTRACT:
The ends of rotary stencils are attached to an attachment ring which is coupled to a drive element on the printing press by means of a universal joint, in the form of a gimbal, so that mis-alignment of the attachment ring with respect to the drive axis of the printing press will not cause distortion of the stencil, during rotation, thus stressing the stencil and causing inaccuracies in reproduction of the pattern to be printed from the stencil. The operating elements of the universal joint, or gimbal construction is preferably protected fron ink, and contamination by means of O-rings, or the like; the connection between the universal joint and the stencil end ring is a bayonet-type cam-recess quick-release connection.
