Abstract: The suction strip is mounted via a tube carrier on a pair of supports so as to pivot about an axis extending longitudinally of the carrier. The pivot axis is located in a vertical plane which passes through the front tip of the suction strip. Pivoting is effected via a leaf spring which mounts the carrier on the supports and at least one adjusting screw. The adjusting screw may have different thread pitches at opposite ends to obtain a coarse and fine control.

Abstract: A deflection compensating press roll is disclosed in which a stationary beam has a barrel mounted for rotation thereabout and a plurality of hydrostatic elements provide selective hydrostatic support along the length of the roll. The support elements are arranged in a plurality of groups to which hydrostatic pressure fluid is directed at selected pressures through pressure fluid paths which are facilitated by separate hydrostatic fluid ducts.

Abstract: The lower guide roll for the press felt is pivotally mounted at one end to pivot upwardly in order to allow the press felt to be mounted or removed from the press. The bearing at the pivot end is secured on a support which, in turn, is pivotal about a horizontal axis below the bearing.

Abstract: An apparatus for controlling a deflection compensating press roll of a rolling mill having a pair of press rolls at least one of which is a deflection compensating roll having a support core, a roll shell rotatably mounted about the core, bearing means disposed between the core and the roll shell adjacent the shell ends, a plurality of support devices engaged between the core and the roll shell to exert forces therebetween and pressure means for pressing the rolls against each other, the control apparatus comprises a frame, a movable member mounted in the frame, means coupled with the support devices and the pressure means and responsive to the forces exerted thereby for exerting a force on the movable member which simulates the forces exerted by the support devices and the pressure means so that the movable member is maintained in an equilibrium position when the forces exerted by the support devices and the pressure means are substantially in equilibrium, means for sensing displacement of the movable member

Abstract: A roll shell is rotatable about a stationary support beam with hydrostatic support means therebetween, preferably a row of piston-cylinder support devices, thereby forming a sag-compensating roll. The shell has external annularly disposed gear teeth at one end. A transmission casing encircles the end and is rotatably mounted thereon by bearings on each side of the gear teeth. Gear means in the casing drives the roll shell. Torque support means is connected between the casing and a fixed support to restrain rotation of the casing, and is advantageously connected to the casing in a plane through the roll axis and the row of support devices.

Abstract: A flexure-compensating roll for a rolling mill having a rotatable roll shell partly of cylindrical shape disposed about a non-rotating beam with hydraulically actuated pistons received in the beam for support of the shell along the line of contact with a mating roll includes inboard bearings for support of the roll shell from stationary piers and outboard bearings for support of the beam from the shell, the inner race of the outboard bearings being fixed to the shell and the outer race thereof being fixed to the beam via plates or spiders, a further spider coupling to the shell for the application of torque thereto.

Abstract: A controlled deflection roll with a fixed beam and surrounding roll shell with pistons guided in radial bores of the beam and bearing against the inner surface of the shell for support thereof is provided, in the branch ducts delivering hydraulic fluid under pressure from a common manifold to the individual pistons, with adjustable valves controlled remotely by means of hydraulic or electrical signals to permit individual control of the shell-supporting pistons.
