Liquid metering assembly comprising a roller (47) for receiving a coating of a liquid, a doctor blade (49) for metering the liquid on the roller to provide a uniform coating of the required thickness prior to transfer of liquid from the roller to a receiving member, and a holder (50) for the blade extending generally parallel with the axis of the roller. The holder (50) is supported between end members (61, 62) which also provide bearing members (64) in which the roller is journaled for rotation. This ensures accurate spacing and loading of the blade relative to the roller and makes the assembly especially useful for metering a thin layer of release oil onto the fuser rollers of a xerographic copying machine. <IMAGE> |
