ABSTRACT:
A inking apparatus includes form rollers brought into rolling contact with vibrating rollers. Each form roller includes a rotatable roller shaft whose axial movement is limited, and a roller body fitted on the roller shaft. Right and left vibration stroke adjusting screws are threadably engaged with male screws at both ends of the roller shaft and are movable in an axial direction of the roller shaft. Compression coil springs are compressed between the right vibration stroke adjusting screw and one of both the ends of the roller body and between the left vibration stroke adjusting screw and the other end of the both ends of the roller body. The compression coil springs define a vibration stroke by positions where the compression coil springs are completely compressed.
