Abstract
An apparatus which forms and transfers thin films of a viscous or freely flowable liquid has a housing which supports or includes a vessel for a supply of liquid, a fountain roll which is rotatable in the housing and a median portion of which extends transversely of an outlet of the vessel so that liquid which flows into the outlet forms a layer on the periphery of the median portion, and a cylindrical doctor having at one end a diametrically extending blade which defines with the periphery of the median portion of the fountain roll a narrow clearance through which a film of liquid passes toward a station where the film is transferred onto a ductor roll. The doctor is adjustable radially of the fountain roll and the latter is surrounded by two O-rings which prevent the liquid layer from spreading from the median portion to the end faces of the fountain roll. A further O-ring is mounted in the housing to sealingly engage and to prevent leakage of liquid along the periphery of the doctor.
