Abstract: An arrangement for controlling the pressing or line force of a controlled deflection roll comprises a common adjustment or setting element for separate controllable supporting force sources or force-applying sources. Between the adjustment element and the force-applying sources there are connected converters for generating control signals in accordance with a conversion function which, depending upon the nature and/or site of the force-applying sources, has different characteristics. The converter enables interposing correction signals.

Abstract: A controlled deflection roll comprising a stationary roll support and a roll shell rotatable about the roll support. The roll shell is guided in radial direction upon the roll support in order to perform displacement movements, typically lift movements. The controlled deflection roll is equipped with a shutoff element, a slide or a valve, which upon exceeding a given displacement magnitude of the roll shell causes outflow of pressurized fluid medium from a pressure line, and thus, prevents the development of the full pressing or contact force which otherwise could lead to destruction or damage of the roll shell. In an overflow line, branching-off of the pressure line, there can be arranged a residual pressure regulator equipped with valve means or throttle means for preventing drop of the pressure in the pressure line below a desired value.

Abstract: A rolling mill contains a controlled deflection roll possessing a roll shell movable, in the pressure or contact plane, radially in relation to a roll support or beam for rotatably mounting the roll shell. The ends of the roll shell are guided in appropriate guide means. The roll shell, in the pressing or contact position of the controlled deflection roll, bears against fixed stops or impact members, so that there is formed a fixed roll. A regulation device serves for determining the magnitude of the impact forces. As the impact or stop member there can be preferably used the ends of the guide means or guides of the roll shell. The impact force is formed by pressure or support elements of the controlled deflection roll or by pistons mounted at the region of the guide means. There also can be provided an external contact or pressing device.

Abstract: A controlled deflection roll contains a stationary support and a roll shell rotatable thereabout. The support has a central bore for the infeed of pressurized fluid medium. In the central bore there are located partition walls and infeed tubes, which deliver to individual sections of the stationary support the pressurized fluid medium at different pressures. The first section of the bore at one end of the stationary support serves for the withdrawal of the medium from the intermediate space or chamber between the roll shell and the support. The partition walls are held in spaced relationship by spacer tubes and secured by means of a tie or tension rod. Each partition wall consists of two telescopically displaceable parts, conjointly limiting a groove for a seal, and the seal can be pressed against the wall of the central bore by drawing together the telescopically displaceable parts.

Abstract: A controlled deflection roll having a roll shell rotatably mounted at its ends at a stationary roll support. Pressure or support elements are located between the roll shell and the roll support. The bearing or mounting arrangement of the roll shell at the roll support is provided with play, in a direction opposite to the direction of application of the force exerted by the pressure elements. In such play there is effective a force opposing the direction of the force of the pressure elements. If this force is exceeded by the force of the pressure elements, then a control device limits the force exerted by the pressure elements to a value which is not dangerous for the roll shell. According to a preferred construction the control device is constituted by a hydraulic shutoff element which, in the case of a hydraulic controlled deflection roll, opens an outflow channel leading from the pressure line or conduit, and thus, lowers the pressure effective in the pressure line.

Abstract: A controlled deflection roll comprising a stationary roll support and a roll shell rotatable about the stationary support. The roll shell is supported upon pressure or support elements which can be activated by pressurized fluid medium at different pressures. At the end of the stationary support there is arranged a supply head means containing pressure regulators, a common infeed line or conduit and outfeed channels, leading to the pressure or support elements. At the center of the supply head means there is formed a relief bore which is connected with the outfeed channels, provided with a slide and serves for the rapid lowering of the pressure which is effective at the pressure or support elements. The pressure regulators are arranged in a star-like configuration at the supply head means.

Abstract: A controlled deflection roll comprising a stationary roll support and a roll shell rotatable about such roll support. The roll shell is guided, with the aid of guide elements, relative to the roll support in the pressure plane of the controlled deflection roll in order to generate lift-off movements. Lift-off pistons are guided in the roll support and bear against inner surfaces of the guide elements. Each of the lift-off pistons can be arranged within guide means of the related guide element, such guide means being bounded by essentially parallel guide surfaces.

Abstract: A controlled deflection roll having a fixed support and a roll shell rotatable thereabout and supported upon hydraulic pressure elements delimiting a number of pressure compartments at the fixed support. A longitudinal bore extends lengthwise of the fixed support and connection bores lead therefrom to the individual pressure compartments. Pressure regulators coact with the pressure elements for setting the pressure of an hydraulic pressurized fluid medium which is infed to the individual pressure compartments. The housings of the pressure regulators and the actuation elements thereof are insertably arranged in the longitudinal bore of the fixed support and connected with a pressurized fluid medium line for the infeed of the pressurized fluid medium. Each housing has an outlet bore, the mouth of which is surrounded by a sealing region and is connectable with the connection bore of the related pressure compartment.

Abstract: A controlled deflection roll comprising a fixed support and a hollow shell rotatable about the support and displaceable relative to the support in the direction of a pressure plane. Between the support and the shell there is located at least one hydrostatic pressure or contact element which is effective in the pressure plane and serves for oppressing the roll shell against a counter roll and thus for forming the pressure force of the roll. Additionally, there is provided at least one hydrostatic lift-off element which is effective in the opposite direction with respect to the contact or pressure element and serves for lifting-off the roll shell from the counter roll. The contact element and the lift-off element can be connected by hydraulic lines or conduits to a source of hydraulic pressurized fluid medium.

Abstract: A deflection compensating roll is disclosed which comprises a support beam, a roll shell rotatably mounted about and defining with said beam an intermediate space therebetween and at least one hydrostatic support element engaged between the beam and the shell for exerting a force against the interior of the shell. The surface of the support element facing the interior of the shell is provided with a plurality of recesses which are supplied with fluid so that a hydrostatic fluid cushion is formed between the face of the support element and the interior of the roll shell. The beam has a longitudinally extending chamber and means for sealing a first region of the chamber which communicates with the fluid receiving recesses from a second region of the chamber which communicates with the intermediate space between the beam and the shell.
