ABSTRACT:
A device for controlling the rotor in a paper stock refiner to locate the rotor in a neutral position in the stator during start-up and shut-down, at which time uneven stock flow and unequal hydraulic pressures may occur tending to move the rotor off floating center so that its refiner surfaces shift toward and possibly into damaging engagement with the stator refiner surfaces. During full operation the rotor shaft is released for normal self-centering or adjustment relative to the stator.
