摘要： A magnetic audio or video tape is smoothed and/or otherwise treated by causing it to pass through one or more calenders wherein a large-diameter primary calender roll is heated from within and the major part of its peripheral surface is surrounded by the running tape. The primary roll rotates about a fixed axis and is surrounded by a cluster of two or more smaller-diameter secondary calender rolls each of which has a viscoelastic peripheral layer and each of which can be individually biased against the adjacent portion of the running tape with a selected force. The magnetic film on the tape is out of contact with the secondary rolls as well as with the guide rollers which cause the tape to advance toward the peripheral surface of the primary roll and thereupon toward a takeup reel.

摘要： The roll assembly of a calender has at least one roll with a deformable shell which surrounds a rigid carrier and whose end portions surround discrete antifriction bearings. The intermediate portion of the shell surrounds one or more rows of hydrostatic supporting elements which can be acted upon by adjustable fluid-operated motors to change the shape of the intermediate portion in a plane including the axes of the one roll and the neighboring roll as well as at right angles to such plane. Stresses which are applied to the bearings for the end portions of the shell are monitored by several sensors which transmit signals to a control system to regulate the deformation of the shell in such a way that the stresses upon the bearings are minimized or reduced to zero. This enables the intermediate portion of the shell to undergo deformation which is best suited for optimum treatment of the material passing through the nip of the one roll and the neighboring roll.

摘要： A roll for use in a calender has a stationary carrier which is surrounded by a hollow cylindrical shell with the interposition of a hydraulically operated displacing unit which can flex selected portions of the shell when necessary so as to establish a preselected nip between the peripheral surface of the shell and the shell of an adjoining roll. The hydrostatic displacing unit is flanked by two antifriction bearings which operate between the carrier and the shell and are lubricated by a circuit which is independent of the circuit that supplies hydraulic fluid to the displacing unit. This renders it possible to use in the displacing unit a fluid whose temperature is much higher than the maximum permissible temperature of lubricant for the bearings. The bearings are sealed from the respective ends of the displacing unit by single seals or by multiple seals, and any leak fluid which penetrates beyond the neighboring seal is evacuated through one or more channels in the carrier and/or in the shell. Lubricant for the bearings may but need not be identical with hydraulic fluid which is supplied to the displacing unit.

摘要： A calender wherein a permanently installed main roll cooperates with at least one exchangeable roll to provide a nip for the passage of a web of paper or the like. The end portions of the exchangeable roll are mounted in bearings which are insertable into and extractible from sockets provided in levers which are pivotably mounted in the frame of the calender. The calender has a transporting unit which is provided with grippers for the bearings and with motors which reciprocate the grippers to extract the bearings from their sockets after the levers are pivoted to positions in which the exchangeable roll is spaced apart from the main roll. The transporting unit thereupon transfers the exchangeable roll onto a mobile rack which can be transported to a station where the exchangeable roll is repaired. The same rack or a discrete second rack can deliver a refurbished exchangeable roll to the transporting unit for introduction of the bearings on the refurbished roll into the sockets on the levers in the frame of the calender before the levers are pivoted to move the refurbished roll into engagement with a running web or with the main roll. Locking devices are provided to releasably hold the bearings in their sockets, and additional locking devices are provided to releasably hold the bearings in sockets which are provided on the rack or racks. The transporting unit can constitute a robot whose grippers then constitute effectors and whose operation is automated to start a roll exchanging operation as soon as one or more sensors in the calender ascertain that the quality of the exchangeable roll is unsatisfactory for further treatment of running webs.

摘要： A roll for use in a calender has a stationary carrier for a hollow cylindrical shell whose end portions are supported by combined radial and axial bearings surrounding annular bearing members which, in turn, surround the end portions of the carrier. The carrier defines with each bearing member a set of chambers which are sealed from the atmosphere and can receive pressurized hydraulic fluid to ensure that the end portions of the shell are biased toward a second roll with a requisite force as well that the end portions of the shell are stabilized against lateral and/or other stray movements. The fluid in the chambers ensures that the shell can be acted upon by large forces without unduly stressing the antifriction bearings. The bearing members flank a hydrostatic bearing unit which acts between the central portion of the shell and the carrier.

摘要： A calender roll wherein a hollow rotary cylindrical shell surrounds a stationary carrier and the latter supports a set of hydraulic cylinder and piston units serving to urge the external surface of a bearing element toward the internal surface of the shell. The external surface of the bearing element is formed with liquid-filled pockets each of which communicates with the cylinder chamber of a pressure generating unit. The cylinder chambers receive pressurized liquid from a pump via first conduits whose resistance to the flow of liquid is more pronounced than that of second conduits which directly connect the cylinder chambers with one or more hydropneumatic accumulators.

摘要： A calender roll wherein the flexible shell is supported by a row of primary hydrostatic bearing elements serving to transmit first forces toward the nip of such roll with a second roll and wherein the shell is further acted upon by a row of secondary hydrostatic bearing elements which generate second forces opposing the first forces. The rate of fluid flow through the secondary bearing elements is regulated with a view to conform the temperature of the shell along the nip of the two rolls to a preselected pattern. To this end, the compensator of a computer in the fluid pressure regulating unit insures that pressure changes are distributed among the primary and secondary bearing elements with a view to match each change of the first forces by an equal change of the second forces. The temperature of the fluid is regulated only ahead of the regulating unit. The compensator cooperates with the secondary bearing elements to ensure that the temperature of the shell can be changed along the nip without altering the temperature of the fluid.

摘要： A roll assembly for use in calenders has a non-rotatable carrier which is surrounded by a rotatable and radially movable hollow cylindrical shell. At least one end of the shell is driven by a pair of gears one of which is mounted in an annular bearing member surrounding a portion of the carrier and the other of which is connected with the one end of the shell. The bearing member shares the radial movements of the shell relative to the carrier. To this end, the radial position of the shell is monitored by one or two sensors in the form of first cylinder and piston units, and the bearing member is adjustable by two second cylinder and piston units. The cylinder chamber of each first unit is connected in circuit with the cylinder chamber of a different second unit, and the ratio of cross-sectional areas of the pistons of the first units to the cross-sectional areas of pistons of the second units is selected in such a way that the radial displacement of the bearing member matches or approximates the radial displacement of the shell. This prevents the application of pronounced stresses to the gears. The fluid in the two circuits is maintained above atmospheric pressure.

摘要： The cylindrical shell of a roll in a calender is rotatable about and is movable radially of a stationary carrier. The shell receives torque from a gear which is rotatably journalled in a housing. The housing is movable radially of the shell by a motor operated in response to signals from a monitoring device which ascertains deviations of the position of the shell from a preselected position. Adjustments of the housing relative to the carrier are proportional to or match the extent of deviation of the position of the shell from the preselected position.
