ABSTRACT The invention relates to a device for the exchange of ink and/or damping solution in the longitudinal direction of the roller in the printing unit of a rotary printing press. Such a device can also be used in a locally tightly re- stricted area to exchange ink and/or damping solution be- tweet non-printing roller areas and such roller areas on the same or a different roller which are used for printing or in which more ink and/or damping solution is required. For this purpose, rotation bodies (3) are provided whose rotation axes (29) run non-parallel to the rollers (1,28) of the printing unit and whose axially non-parallel ink- exchanging envelope surfaces (2) in offset zones (4,5) contact the rollers (1,28) of the printing unit. Fig. 4 shows, by way of example, the possible configuration of rotation bodies (3) in the form of taper rollers for the exchange of ink and/or damping solution between two rollers (1,28) rotating in opposite directions.
