Abstract

A dampening device for an offset rotary printing machine comprises a fountain roller (1) rotating at a first surface speed and an inking roller (4) rotating at a second surface speed. A transfer roller (3) is provided between the two, and is driven by frictional contact with the inking roller (4). The inking roller 4 is driven by frictional contact with the plate cylinder (5) and a positively driven ink distribution roller (6). The fountain roller (1) is driven from the transfer roller (3) by means of a drive transmission. In this way, the surface speeds of the transfer roller (3) and the fountain roller (1) can adapt automatically to any alteration in the surface speeds of the plate cylinder (5) or the ink distributor roller (6), without the necessity for additional control devices. The drive transmission may be by toothed gearing, or by a belt. The fountain roller 1 may be provided with a brake to allow adjustment of its rotation. <IMAGE>
