Abstract
In a rotary printing machine, an arrangement for mounting an applicator roller and a preceding roller in a fluid feed stream journals the applicator roller and the preceding roller to the printing machine frame with substantial bearing play, and spring loads the applicator roller against the bearing surface away from the plate cylinder. On passing through the cylinder gap the applicator rollers of inking, damping or varnishing units in sheet-fed offset presses are jolted both at the start and end of the gap. The resulting different flattening of the soft applicator rollers causes roller marks, which should be avoided. For this purpose the applicator roller and the preceding roller are braced against each other by springs, so that their bearing play is eliminated and the distance between shafts is constant. This condition is also maintained on passage through the gap. Conveyance of liquid between applicator rollers and the preceding rollers is thus constant.
