Abstract
A cylinder, which is part of an inking system or of a dampening system, has a rotary individual drive which is embodied as a drive motor. A changeable drive is also provided. The rotary drive is driven by the drive motors by a bevel or angular gear.
Claims11
A distribution roller for use in at least one of an inking system and a dampening system of an offset rotary printing press comprising:
- a roller train defining a fluid stream in said one of said inking system and said dampening system, said fluid stream extending from a supply roller of one of ink in said inking system and of dampening fluid in said dampening system to an application roller engageable with a forme cylinder of said offset rotary printing press, said distribution roller being an axially reciprocating distribution roller in said fluid stream of said roller train and being intermediate said supply roller and said application roller;
- a roller body of said distribution roller and having first and second roller body ends;
- spaced first and second pivotable levers supporting said first and second ends of said roller body for rotation of said roller body about an axis of rotation of said roller body;
- a distribution roller rotary drive mechanism including a rotary drive motor, said distribution roller rotary drive mechanism being located at one of said first and second ends of said roller body on one of said first and second pivotable levers and being usable to rotate said roller body about said axis of rotation of said roller body;
- and
- a distribution roller traversing drive mechanism located at the other of said first and second ends of said roller body on the other of said first and second pivotable levers and being usable for traversing said roller body along said axis of rotation of said roller body, each of said roller body first and second ends, said roller traversing drive mechanism and said roller rotary drive mechanism being supported on said first and second pivotable levers for movement of each of said roller body, said roller traversing drive mechanism and said roller rotary drive mechanism in a direction which is perpendicular to said axis of rotation of said roller body.

A roller for use in at least one of an inking system and a dampening system of an offset rotary printing press comprising:
- a roller train defining a fluid stream in said one of said inking system and said dampening system, said fluid stream extending from a supply roller of one of ink in said inking system and of dampening fluid in said dampening system to an application roller engageable with a forme cylinder of said offset rotary printing press, said roller being an axially reciprocating distribution roller in said fluid stream of said roller train and being intermediate said supply roller and said application roller;
- a roller body of said distribution miler and including spaced first and second roller body ends, said roller body being supported for movement perpendicular to an axis of rotation of said roller body;
- spaced first and second pivotable levers supporting said first and second roller body ends;
- a roller traversing drive mechanism positioned at said first end of said roller body an one of said first and second pivotable levers, said roller traversing drive mechanism being usable to move said roller body in a traversing movement in an axial direction of said axis of rotation of said roller body;
- a roller rotary drive mechanism located at said second end of said roller body on the other of said first and second pivotable levers, said roller rotary drive mechanism being usable to rotate said roller body about said axis of rotation of said roller body, said roller rotary drive mechanism and said roller traversing drive mechanism being supported by said first and second pivotable levers and being movable with said roller body in said direction perpendicular to said axis of rotation of said roller body;
- and
- a coaxial drive shaft and a coupling in said distribution roller rotary drive mechanism, said drive shaft being fixed in place in said direction of said axis of rotation of said roller body, said coupling being adapted to transmit a torque from said roller rotary drive mechanism to said roller body and to permit said axial traversing movement between said drive shaft and said roller body.
