Apparatus for removing liquid from a press roll sleeve or belt on a paper making machine

Abstract

A blade ( 20 ) for wiping water from a sleeve ( 26 ) mounted on a press roll ( 14 ) in a paper making machine is adjustably mounted on the machine for movement toward and away from the sleeve ( 26 ). The wiper blade ( 20 ) is positionable against the surface of the sleeve ( 26 ) to wipe water therefrom adjacent and upstream from the nip between the sleeve ( 26 ) and a mating press roll ( 12 ).

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:  
     
         1 . A press roll system in a paper making machine comprising: 
 a press roll mounted in a framework;    a surface-patterned sleeve on the press roll;    a wiper blade mounted on said framework, said wiper blade having a blade edge positionable against the surface of said sleeve; and,    a trough positioned beneath said wiper blade.    
     
     
         2 . The system of  claim 1 , wherein said press roll defines a nip region, said wiper blade being positioned upstream of the nip region.  
     
     
         3 . The system of  claim 1  wherein said blade is mounted for swinging movement between a first position wherein said blade edge is positioned in contact with the surface of said sleeve and a second position wherein said blade edge is spaced from said surface.  
     
     
         4 . The system of  claim 1  wherein said wiper blade is mounted for movement toward and away from said sleeve.  
     
     
         5 . The system of  claim 1  wherein said sleeve and said blade comprise the same material.  
     
     
         6 . The system of claim  8  wherein said material comprises polyethylene.  
     
     
         7 . The system of  claim 1  wherein said surface-patterned sleeve includes at least one of a surface groove pattern and hole pattern.
