Abstract

For the accurate register alignment of a blanket on a blanket or plate cylinder for selected-area, in-line varnishing in a rotary press, clamping devices are provided with registration means each comprising two axially spaced, radially directed register pins which are situated beneath the outer surface of the cylinder and cooperate in exact register with recesses provided in the associated ends of the blanket. The clamping device for the front blanket end is adapted to be fixed in a zero position by means of associated markings at the front blanket end and an associated marking on the blanket or plate cylinder. The two clamping devices together with the rotatable tensioning spindles are disposed to be axially displaceable in the plate cylinder by means of adjusting devices.
