<p>An inker mechanism has an inking roller (10, 12) rotatably mounted on a frame. The inking roller has a degree of freedom allowing the roller to shift axially. A bearing assembly (54, 56) is coaxially connected to the roller for axially shifting the roller. This bearing assembly has an outer shell with a universal joint (72, 74). The inker mechanism also has a cam (50) and a pivotally mounted lever (44) connected between this cam and the universal joint. This cam can articulate the lever to oscillate the roller axially.</p> |
