Abstract

To improve the throw-on and throw-off movement of the rollers in the roller train of inking or dampening units of a printing machine, an improved and simpler throw-on and throw-off device is provided. For this purpose, intermediate rollers are carried in bearing levers, which enable the intermediate rollers to be thrown off from adjacent distributor rollers. For the simple parallel throw-on of the intermediate rollers, their bearing levers carry cam rollers which are supported on an adjusting rod. The adjusting rod has cam sections which cooperate with the cam rollers, and in response to longitudinal displacement of the adjusting rod, the intermediate rollers are moveable in throw-on and throw-off directions.
