摘要： In a press roll having a stationary support member and a roll shell rotatable about the stationary support member and movable in a predeterminate support or pressing direction throughout the entire width of the press roll, the provision of guide devices for the rotatable roll shell enable accomplishing an axial and radial guiding of the rotatable roll shell with minimum friction and without using roller bearings. These guide devices comprise hydrostatic support or pressure elements which can be adjusted in the predeterminate support or pressing direction. Bearing surfaces of the hydrostatic support elements and running or travel surfaces at the roll shell are spherically designed, for instance provided in mirror-image relationship to one another at both ends of the press roll, or at only one end thereof, or at the central or intermediate region of the press roll.

摘要： The controlled deflection roll comprises a rotatable roll shell supported at a stationary support member by means of a plurality of hydrostatic pressure elements. The hydrostatic pressure elements are sealingly movably guided by guide structure, for example, bores, which define cylinder chambers. Each cylinder chamber is connected by a feed system comprising a feed channel to a source of a hydraulic pressure medium. Between each feed channel and the related hydrostatic pressure element, there is arranged a damping body provided with at least one throttle location, for example throttle bores, through which the hydraulic pressure medium can flow. The damping body defines essentially the only connection between the feed channel and the cylinder chamber. Possibly occurring oscillations or vibrations of the rotatable roll shell relative to the stationary support member are damped by these damping bodies and, accordingly, transmission of such oscillations or vibrations to the hydraulic pressure medium feed system is prevented.

摘要： The apparatus for neutralizing overhanging loads is supported at the roll stand of a calender which opens in downward direction. This apparatus is arranged at both sides of a roll and, during operation, presses from below against the roll suspensions in a predetermined or required position of the roll. This is accomplished by a force which compensates for the overhanging loads. This force is generated or set by movable force transmitters, dimensionally deformable force transmitters or displaceable force transmitters. Upon opening the calender, a force greater than the set force acts upon the load neutralizing apparatus and the force transmitters are moved, dimensionally deformed or displaced, as the case may be, such that a displacement path of the roll into a lower lowered position is provided. The force transmitters for generating the force which compensates for the overhanging loads can be a spring assembly, an air spring or a column or head of liquid supported by a gas cushion.

摘要： An apparatus for determining the pressure forces effective in a rolling mill having at least one controlled deflection roll and at least one counter roll, there being provided beams for simulating the stiffness or rigidity of the counter roll and the shell of the controlled deflection roll. These are further provided pressure elements which simulate the effect of the hydrostatic pressure or support elements of the controlled deflection roll, and measuring elements serve to measure the pressure between the beams. External pressure elements can serve to simulate the effect of external contact or pressure cylinders. With a rolling mill having a number of controlled deflection rolls and a number of solid counter rolls, the beams, the pressure elements and the measuring elements can be appropriately grouped or assembled together. The measuring elements deliver signals which can be employed for controlling or regulating a corresponding rolling mill which is simulated.

摘要： 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. A control device or means serves for the selective connection of a conduit of the contact element or the lift-off element with the source of hydraulic pressurized fluid medium and for simultaneously connecting the conduit of the element disconnected from the source with a drainage or outflow line or conduit.

摘要： A method of, and washing machine or washer for, washing stock suspensions, wherein a rotatable cylinder having a solid smooth surface is encircled along a portion of its circumference by a movable endless wire or filter band. The stock suspension to be dewatered and washed is infed by a flat jet nozzle between the rotatable solid cylinder and the movable endless wire. The fiber web formed between the rotatable solid cylinder and the movable endless wire has a weight of less than 100 grams per square meter, preferably 30 to 70 grams per square meter. The wire speed and the circumferential speed of the rotatable solid cylinder is in the order of about 400 to 1,200 meters per minute. After through-flow of the stock suspension between the rotatable solid cylinder and the movable endless wire, the dewatered and washed fiber material is removed from the movable endless wire and the rotatable solid cylinder, respectively, collected in a collecting container and delivered for further processing. At least selected portions of the contaminated water removal from the washed fiber material is fed to a clarifier and the clear water recycled back by means of a mixing pump to the washing machine.

摘要： A rolling mill or apparatus comprises position detectors or sensors which are disposed upon movable roll shells or movable solid rolls possessing, for instance, hydraulic support or pressure elements. The position detectors act upon regulators for regulating a force differential between a larger pressing force exerted by bottom or lower support elements in relation to a lesser pressing force exerted by top or upper support elements. The excess or resultant of the pressing force produced by the bottom support or pressure elements decreases with increasing height of the position of the rolls until there is established an equilibrium position. During operation there exists an equilibrium condition between the upwardly directed force of the bottom support elements and the sum of the downwardly directed pressing force of the upper or top support elements and the weight of all of the parts therebetween.
