PURPOSE:To make ink film even on an inking roller and prevent obstruction (e.g., occurrence of ghost) to printing by reciprocally moving a rider roller provided closely in the face of the periphery of an inking roller in its axial direction. CONSTITUTION:A grooved pulley 42 is provided to the end of a rider roller 37 supported rotatably and moveably in the axial direction by a bearing lever 35, and also a cam 41 is provided to one end of the shaft 34 of a motor 33. The roller 46 of a shifter 44 rotatably attached to a bracket 43 is fitted into the grooved pulley 42 and a cam follower 45 is fitted into the cam 41. The rider roller 37 is moved reciprocally in its axial direction by the rotation of the motor 33. Ink supplied from a shaking roller 22 is supplied to a plate cylinder 2, and then ink film remaining in an uneven state on the surface of the inking roller 28 is smoothened by reciprocally moving the rider roller 37 turning closely in the face of the roller 28 in the axial direction. Thus, printing obstruction can be prevented. |
