ABSTRACT:
An apparatus such as a printing apparatus employing an ink fountain assembly which includes a roller and metering blade, supported between housing walls for purposes of metering ink in the course of a printing operation. Seals are provided for sealing against leakage of ink in the region of the assembly where the roller ends are journalled for rotation. The seals comprise compressible, annular members mounted at each end of the roller. The seals define mating surfaces for engaging with mounting elements so that the seals are held against rotation as the printing operation takes place. The seals are compressed to provide a snug fit with the roller ends, and they define surfaces which develop a minimum of friction with these engaging roller ends.
