ABSTRACT:
A press for dewatering papermaking pulp has a pair of adjacent perforated cylindrical rolls which define a continuously converging nip and a vat shell adjacent the rolls which provides enhanced bottom access to the press rolls by means of a door which is hinged to swing downward and away from the bottom of the press vat. A hoist mechanism raises and lowers the unhinged side of the door as required, and retractable keys latch the door in a sealing position against the vat. A shock absorber mechanism is provided to limit the speed at which the unhinged side of the door can fall when being lowered.
