Summary:A hydraulic roll protection system in which positioning of an adjustable roll relative to a fixed roll is caused by adjusting screws acting on movable journal boxes through a pressurized piston cylinder device. A relief valve between a hand pump and the cylinder acts to relieve excessive pressures. A switch valve connects the hand pump alternately to advance the roll journal to normal gap positions and to retract the roll from the fixed roll.
