ABSTRACT:
A paper machine has a high pressure liquid pump for use with a liquid slitter for slitting a fiber material web. The high pressure liquid pump includes a pump shell having an axis of rotation and an annular smooth inwardly facing surface. The inwardly facing surface is configured for carrying a film of liquid thereon. A hydraulic shoe having an outer convexly curved working face is in close running engagement with the inwardly facing surface. A pivotal arm is connected with the shoe and positions the shoe relative to the inwardly facing surface. The arm is movable toward and away from the inwardly facing surface. A hydraulic pressure member is engaged with the arm for urging the shoe toward the inwardly facing surface dependent upon a hydraulic pressure therein. The pump shell is driven about the axis of rotation, thereby continuously moving the inwardly facing surface of the pump shell past the shoe and continuously forming a hydraulic wedge of high-pressure liquid between the inwardly facing surface and the working face.
