Abstract
A roller assembly (10) is provided which includes an anilox roller (12) mounted with a head (14) for applying a liquid (18) to another surface, such as a delivery, printing plate blanket, or impression cylinder. An end dam (42) is provided at each end of the head (14), which defines a curved seal surface (46) which bears against the bearer surface (58) at each end of the anilox roller (12). The curved seal surface (46) and bearer surface (58) form an end seal for the roller assembly. If desired, lubrication can be provided between the curved seal surface (46) and the bearer surface (58).
