Abstract
An improved Uhle box for use in a paper press includes an elongated, generally U-shaped support structure closed at its opposite ends by deckle pieces, and with each upstanding leg including a cylindrical recess for rotatably mounting a cylinder on which the wet felt is supported. The central portion of the support structure defines a vacuum zone which is in communication with a vacuum source. Lubrication is provided to the rotatable cylinder as the wet felt is passed over the Uhle box, and moisture is extracted from the wet felt as it passes over the vacuum zone.
