Abstract
An apparatus is disclosed for cleaning a porous cover of a press roll of a papermaking machine. The apparatus includes a hydrostatic bearing disposed adjacent to the porous cover, the bearing defining a concave surface for cooperating with porous cover. The bearing defines a fluid conveying passageway having a first and a second end. The first end of the passageway is connected to a source of pressurized fluid and the second end is in fluid communication with the concave surface such that in use of the apparatus, when the porous cover of the press roll rotates, the fluid passes through the passageway and along the concave surface and between the concave surface and the porous cover. The pressurized fluid flow inwardly through the porous cover for flushing contaminants lodged within the porous cover outwardly away from the porous cover thereby inhibiting the buildup of comtaminants on the external surface of the porous cover that would otherwise impair the water absorbing capabilities of the cover.
