Cylinder of an inking or dampening system

A roller adapted for use with at least one of an inking system and a dampening system of a printing press comprising:

• means supporting said roller for traversing movement in an axial direction of said roller;
• a rotatory drive mechanism including a drive motor adapted to rotate said roller about said axis of rotation;
• and
• means supporting said roller and said drive motor for movement in a direction perpendicular to said axis of rotation.

A roller adapted for use with at least one of an inking system and a dampening system of a printing press comprising:

• a roller body including spaced first and second ends;
• a traversing gear at said first end of said roller body and adapted to move said roller in a direction of an axis of rotation of said roller body;
• a drive mechanism located at said second end of said roller body and adapted to rotate said roller body about said axis of rotation of said roller body;
• and
• a coaxial drive shaft and a coupling in said 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 drive mechanism to said roller body and to permit axial movement between said drive shaft and said roller body.

A fluid application system of a rotary printing press comprising:

• a first roller having a first roller axis of rotation;
• a second roller working with said first roller in a print-on position, said second roller having a second roller axis of rotation;
• a first pivotable lever supporting said first roller for rotation about said first roller axis of rotation, said first pivotable lever being pivotable about a first pivot shaft;
• and
• a second pivotable lever supporting said second roller for rotation about said second roller axis of rotation, said second pivotable lever being pivotable about a second pivot shaft, said first pivot shaft connecting with said second roller axis of rotation.
