An inker mechanism has an inking roller rotatably mounted on a frame. The inking roller has a degree of freedom allowing the roller to shift axially. A bearing assembly is coaxially connected to the roller for axially shifting the roller. This bearing assembly has an outer shell with a universal joint. The inker mechanism also has a cam and a pivotally mounted lever connected between this cam and the universal joint. This cam can articulate the lever to oscillate the roller axially. |
