Patent ID: 8322281

Claim:
An inking unit of a printing press comprising: a forme cylinder in said printing press; an inking roller train in said inking unit and including a plurality of inking rollers usable to ink said forme cylinder; first, second and third ink forme rollers in said inking roller train and each in engagement with said forme cylinder; a first distribution cylinder in said inking roller train, said first distribution cylinder being in frictional contact with two adjacent ones of said ink forme rollers and being rotationally driven in a production direction of rotation of said inking unit solely by said frictional contact with said two adjacent ones of said ink forme rollers in said inking roller train; a second distribution cylinder in said inking roller train, said second distribution cylinder being in contact with a third one of said ink forme rollers; a drive motor in said inking unit; a first mechanical drive connection between said drive motor and said second distribution cylinder for positively rotationally driving said second distribution cylinder both in said production direction of rotation of said inking unit and counter to said production direction of rotation of said inking unit by said drive motor; and a second mechanical drive connection between said drive motor and said first distribution cylinder for positively rotationally driving said first distribution cylinder counter to said production direction of rotation of said inking unit, said second mechanical drive connection between said first distribution cylinder and said drive motor including a one-way clutch which is operable to transmit positive drive rotation to said first distribution cylinder from said drive motor only counter to said production direction of rotation of said inking unit.
