Abstract
An inking unit is for a rotary printing press having ink rollers for providing ink to a printing plate of a plate cylinder. The inking unit includes an ink fountain and an ink fountain roller for receiving a supply of the ink thereon from the ink fountain. A first distributor roller transfers ink thereon to the ink rollers. A transfer roller is disposed between the ink fountain roller and the first distributor roller for transferring at least some of the ink on the ink fountain roller to the first distributor roller. The transfer roller is generally cylindrical and includes a surface which has a circumference which alternately includes raised areas and recessed areas. The transfer roller is in contact with the ink fountain roller at at least one of the raised areas to receive some of the ink therefrom when at least one of the recessed areas is adjacent the first distributor roller to prevent contact therebeween. Additionally, the transfer roller is in contact with the first distributor roller at at least one of the raised areas to supply some of the ink thereto when at least one of the recessed areas is adjacent the ink fountain roller to prevent contact therebetween.
