There are many applications in fluid handling situations where a blade (rigid or conformable) is brought into contact or close proximity with a driven roller, for the purpose of controlling or metering the fluid level on the roller. For simplicity of mounting these blades have usually been positioned parallel to the axis of the roller. In this proposal the blade is inclined to the axis of the roller (see diagram) by some small amount. When the driven roller (1) rotates as indicated, fluid (3) contained within trough (2) is lifted, following roll rotation until it is arrested by blade (4). By inclining or skewing the blade (4) through some small angle (5) the oil is arrested by the blade can be caused to move along the blade as indicated by arrow (6).
