  • Patent number: 4895070
    Abstract: A liquid transfer assembly is shown which transfers a predetermined thickness of liquid to a moving surface, the assembly employing a shearing action to achieve the predetermined thickness. The system includes a supply means for providing a source of the liquid; a first arcuately shaped surface which moves at a first speed and is adapted to contact the supply means so as to obtain a coating of liquid on its surface. A second surface is juxtaposed to the first surface but not in contact therewith, moves at a second speed different from the first speed; and the distance between the two surfaces is sufficiently close that the liquid on the first surface comes in contact with the second surface at their nearest point of proximity. Thus, by virtue of the different surface velocities, the liquid is subjected to a shearing action at the nearest point of proximity with a determined amount thereof being transferred to the second surface.
