VORRICHTUNG ZUR WALZENEINSTELLUNG IN DRUCKMASCHINEN

For engaging, disengaging and adjusting rollers in printing units of, for example, offset printing machines, mechanisms are provided, which permit straight guiding and clamping of the rollers in a particular position. For the simple, compact design of a roller bearing which can be adjusted sensitively, provision is made for a pneumatic drive 5 to act coaxially with the roller axis on a fork 14 as a clamping element between a housing 6 and a roller holder 8 which is displaceable therein in a linear fashion on rolling guides 9, 10. In this case, fork continuations 15 clamp the roller holder 8 in the housing 6 by bending their connection 27. The housing 6 can be rotatably clamped to adjust the direction of action in the machine frame 4.
