ABSTRACT:
A rotary machine for printing or otherwise applying ink or other liquidous composition to a rotary receiving roll carried by a frame and having a longitudinal rotational axis and a peripheral surface. One or more doctor blades having a doctoring edge(s) contact the roll peripheral surface. A blade support for the doctor blade includes or is connected to an aligning member having a registration surface which is held in closely confronting or directly contacting relationship with a portion of the peripheral surface and/or with a portion of a projecting member which projects from the roll. The registration surface has a connection with the doctor blade holder for maintaining a substantially fixed radial distance relationship between the holder and the rotational axis of the roll. The amount of operator effort required to adjust the doctor blade is minimized, even when a reservoir which supplies ink or other liquidous composition to the roll is substantially or completely enclosed to prevent escape of noxious vapors into the workplace.
