Roller assembly for rotary printing machine has bearing pins at end of roller mounted in two axially spaced bearings on each side to prevent sagging of the roller

摘要

The rollers (16) are mounted rotatable in bearings (21, 22) by bearing pins (19, 20) at their ends. The bearing pins of one roller is mounted each time in two bearings and these bearings are arranged axially spaced from each other wherein the spacing considerably reduces the sagging of the roller. The external diameter of the bearing pins of one roller is equal to or only one finishing step smaller than the outer diameter of the roller or of the roller core (17) in the case of a coated roller or roller provided with tubular sleeve.
