ABSTRACT:
An anti rewet deck is provided for press rolls used to increase consistency of fibrous pulp slurry from approximately 4 percent up to about 30 to 50 percent. This is accomplished by biasing the location of the drainage holes in the roll shell to the forward edge of the drainage compartments within the roll shell. To avoid the necessity for handing of the rolls, a mechanism is provided for accomplishing the purposes of minimizing rewet at practical production rates by providing baffle plates which effectively orient the draining pattern in the desired direction. Such baffles can be permanently or removably installed once the desired handing of the rolls is determined.
