    摘要: A calender roll whose shell consists of ferromagnetic material is heated by several groups of electromagnets which are mounted within the shell on a stationary carrier and whose pole shoes are adjacent to the internal surface of the shell. The temperature of the external surface of the shell is monitored at several locations as considered in the axial direction of the roll, and the resulting signals are compared with reference signals denoting the optimum or desired temperatures at such locations. Signals denoting the differences between the actual temperature signals and desired temperature signals are used to regulate the characteristics of electric current which is supplied to the windings of the electromagnets. Each electromagnet of each group can be regulated independently of all other electromagnets. Alternatively, two or more electromagnets of each group or entire groups of electromagnets may be regulated simultaneously. Additional electromagnets are provided to heat the end portions of the shell. Alternatively, such end portions can be heated by the rotors of electric motors which rotate the shell. The characteristics of current which is supplied to the windings of certain electromagnets can be influenced by signals which denote the magnitude of flexural stresses upon selected portions of the shell so that the corresponding electromagnets oppose deformation of adjacent portions of the shell.

    摘要: A roll which can be used in a calender to bear upon a web of textile material, paper or the like while the web travels between the peripheral surface of a floating shell of the roll and a counterroll. The shell surrounds a non-rotatable shaft which carries several rows of discrete electromagnets extending in parallelism with the axis of the shaft and along an arc of at least 200 degrees, as considered in the circumferential direction of the shaft. The electromagnets can be energized to a different extent so as to subject the magnetizable material of the shell to forces of different magnitude and to thus counteract the tendency of the shell to undergo deformation in response to the action of forces which act radially of the shell or which tend to impart to the shell vibratory movements. Additional electromagnets can be provided to cooperate with a radially inwardly extending flange at one end of the shell to hold the latter against excessive movements from an optimum axial position.

    摘要: A roll for use in a calender or a like machine has a carrier which is surrounded by a flexible cylindrical shell. One or more hydrostatic displacing units are installed between the carrier and the shell to deform, when necessary, one or more selected portions of the shell. Each displacing unit has a bearing element with an external surface which is closely adjacent the internal surface of the shell and has one or more pockets for reception of a heated pressurized hydraulic fluid. Each bearing element has a second surface which faces away from the external surface, and the respective displacing unit further comprises one or more plenum chambers adjacent the second surface of the bearing element. The pocket or pockets of the bearing element receive heated fluid from a first source, and the plenum chamber or chambers of the bearing element receive compressed oil or another hydraulic fluid from a second source which can include one or more parts of the first source or vice versa. Each plenum chamber can discharge a stream of oil by way of a flow restrictor to thus prevent stagnation and/or overheating of compressed oil therein. The thus discharged oil can be returned to the source of compressed oil.

    摘要: A roll for use in the system of rolls of a calender has a stationary carrier which is surrounded by a deformable hollow cylindrical shell movable radially relative to the carrier and having end portions which surround and are rotatable relative to rings which are also movable relative to the carrier in the radial direction of the shell. The rings can be arrested in selected positions with reference to the carrier by pairs of hydraulic cylinder and piston units which are connected with the outlets of pumps or with the outlet of a single pump by conduits containing shutoff valves. Refilling devices are provided to compensate for leakage of fluid from the chambers. The shell is deformable by rows of hydrostatic supporting elements which react against the carrier and bear against the internal surface of the shell.

    摘要: A pressure roll for use in calenders has a stationary carrier for a shell which is rotatable and movable radially of the carrier. The end portions of the shell surround antifriction bearings which, in turn, surround sleeves capable of moving radially of stubs constituting the end portions of the carrier. The sleeves are pivotally connected to the carrier for oscillatory movement about an axis which is parallel to the axis of the carrier and is angularly offset from one or more hydrostatic or otherwise configurated supporting devices operating between the carrier and the shell to change the radial position of the shell and/or to change the shape of one or more selected portions of the shell. Pivotal mounting of the sleeves on the carrier reduces friction and facilitates accurate adjustment of the radial position of the shell with reference to the carrier.

    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 calender wherein the bearings for the end portions of the uppermost roll carry pressure transducers in the form of inflatable plenum chambers or hydraulic cylinder and piston units operable to bear against the lower end faces of vertical feed screws which are axially movably mounted in the support to move the bearings through distances of up to 800 mm. The pressure transducers can shift the bearings for the uppermost roll through distances of up to 25 mm, and they are movable transversely of the respective feed screws or vice versa to compensate for manufacturing tolerances, wear and/or unequal stresses. The lowermost roll is normally held at a predetermined level by a pair of fluid-operated motors which urge the respective bearings against the undersides of stops provided therefor on the support.
