Abstract
A cylindrical ink roller rotates as a result of being in tangential line contact with an adjacent roller that is driven rotationally. The roller is suspended for rotation and axial oscillation on bearing cages including bushing for turning and sliding on the shaft. A plurality of springy curved steel wire ribs have corresponding one ends fastened to the bushing and the ribs extend axially for their corresponding opposite ends to fasten to a ring member which fits inside of the roller. The ribs flex or bend slightly to allow the roller to be forced into perfect parallelism with the adjacent roller. The open ribbed roller suspension cages afford free flow of air axially through the roller for cooling it. One or more fans can be installed in the roller. A mechanism for oscillating the roller axially is confined inside of the roller and so designed that cooling air can flow past it.
