Vibration damping device for rotating cylinders

Abstract From the Canadian patent

A damping device for reducing vibration particularly, cylinder bounce in rotating cylinders such as printing, cylinders. The damping device is a multilayered insert of elastomeric and rigid materials. The layers are preferably laminated together and more preferably the elastomeric and rigid layers are alternated throughout the damping device. The insert is located in a housing on the cylinder so as to be flush with the cylinder's outer surface. The damping device may have variable damping abilities formed by the selection of materials, location of materials and/or the use of filled orifices of different damping material in the inserts.
