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.
Claims19
A printing press comprising a plurality of rollers disposed in parallel relation to each other, at least one of said rollers being mounted for pivotal movement between throw-on and throw-off positions with respect to other of said rollers, a pivot member rotatably supporting said one roller, said pivot member being mounted for pivotal movement, an adjusting rod disposed in parallel relation to the axis of said rollers, said pivot member having a follower portion biased into engagement with said adjusting rod, said adjusting rod being linearly moveable in a direction parallel to the axis of said rollers, and said pivot member and one roller supported thereby being pivotal between throw-on and throw-off positions with respect to said other rollers in response to linear movement of said adjusting rod.
A printing press comprising rollers in parallel relation to each other, a plurality of said rollers being mounted for throw-on and throw-off movement with respect to other of said rollers, said plurality of rollers each having a respective holder for rotatably supporting the roller, said holder for each of said plurality of said rollers being moveable for moving the respective roller supported thereby between throw-on and throw-off positions relative to said other rollers, and a single linearly moveable adjusting device arranged parallel to the axis of said rollers and being operable for moving said holders and the rollers supported thereby between throw-on and throw-off positions in response to linear movement of said adjusting device in a direction parallel to the axis of said rollers.
A printing press comprising a plate cylinder, a pair of distributor rollers, a pair of intermediate rollers for engagement with said distributor rollers, and a further distributor roller for engagement with the intermediate rollers, said intermediate rollers each being rotatably supported by a bearing lever, said bearing levers each being mounted for pivotal movement with respect to a common axis, and a throw-on and throw-off adjusting device arranged parallel to the axis of said rollers and being operable for pivoting said bearing levers and the intermediate rollers supported thereby between throw-off and throw-on portions with respect to said pair of distributor rollers in response to linear movement of said adjusting device in a direction parallel to the axis of said rollers.
