VARIABLE NIP PRESS HAVING ROLLS MAINTAINED ON PARALLEL AXES

摘要

A press comprising a plurality of press rolls rotatable about parallel axes, wherein one of the press rolls is laterally movable relative to the other to vary the cross-section of the therebetween nip. Pressing force is applied to the laterally movable press roll by a plurality of separate link systems actuated by individual fluid pressure operated actuators; and the link systems are interconnected by a torsion bar which causes the link systems to maintain the axes of the press rolls parallel.
