Abstract (en)
[origin: US4742769A] Roll-off shocks of cylinders, typically rubber blanket cylinders with respect to each other, are ameliorated or avoided by inserting a filler element into the groove which is located in the median third of the cylinder, but does not extend over the entire length thereof. The filler element is supported on the bottom of the groove, preferably over a damping or resilient element, and has a dimension which is equal to the outer circumference (44) of the bearer ring or the theoretical pitch circle (45) of a drive gear of the cylinder, with tolerance of not more than about +/-0.05 mm. In order to insert the filler elements into the respcective grooves, the cover layers or, if necessary, also the substrate supports of rubber blankets, are removed in the region of the axial length of the filler element. Preferably, the filler elements are made of metal.
