摘要： The invention concerns an adjustable-crown roll having a stationary roll axle which is supported on the machine frame by means of articulated bearings, and a roll mantle which is arranged to revolve on the axle. Hydrostatic loading members or an equivalent pressure fluid chamber or series of chambers are arranged in the space between the axle and the roll mantle. By means of the loading members or equivalent, the profile of a nip formed with a counter-roll of the roll is regulated. A support bushing arranged concentrically with the roll mantle is attached to one end of the roll mantle and revolves along with the roll mantle. A bearing is installed on the support bushing. The bearing receives axial forces from the roll mantle and transfers the same to the machine frame through the non-revolving bearing block or housing of the bearing. The bearing is arranged, in the axial direction, outside the roll, whereby the roll is suitable for use as a hot roll.

摘要： The invention concerns a method and apparatus for regulating the temperature of an adjustable-crown roll. The roll mantle (12) arranged to revolve on the stationary axle (11) of the roll (10) is loaded by passing a pressure medium into a pressure chamber (15) or series of chambers formed between the axle (11) and the mantle (12) so as to correct the deflection of the roll mantle (12). The roll (10) is additionally heated/cooled by passing heating/cooling fluid into the roll (10). The heating/cooling fluid used for the regulation of the temperature of the roll (10) is introduced into the roll (10) so as to be substantially uniformly distributed over the surface area of the roll (10) such that heat is removed or produced in the radial direction of the roll. The heating or cooling fluid is passed into the pressure chamber (15) in the roll (10), in which case, by its means, pressurization of the chamber (15) is also accomplished, and/or into the unpressurized chamber (16) of the roll (10), in which case the function of the fluid is exclusively regulation of the temperature. The invention further concerns a regulation system for carrying out the method.

摘要： A glide shoe arrangement for a variable crown roll is disclosed. The roll comprises a fixed central axle on which a hollow cylindrical roll mantle is rotatably journalled. A series of piston-glide shoe arrangements are fitted along the length of the roll between the axle and the inner surface of the roll mantle and are adapted to be loaded by hydraulic pressure fluid so that each piston loads a corresponding glide shoe against the inner surface of the roll mantle to control the distribution of nip pressure in a nip formed by the variable crown roll and a counter roll. The piston-glide shoe arrangements are fitted in cylinder bores formed in the axle. Spherical surface bearings are fitted between the loading pistons and the glide shoes, the center of curvature or rotation of the bearing surfaces being located on the side of the glide shoe. A pin-shaped projection is fitted in the loading piston and extends through the spherical bearing. A sealing articulation arrangement is situated between the pin-shaped projection and either the glide shoe or a projection part attached to the glide shoe. The pressure fluid is passed through ducts from the loading space of the cylinder bore through the pin-shaped projection and into hydrostatic lubrication spaces on the glide shoe.

摘要： A method for providing a tubular roll mantle of a roll for a paper machine or equivalent with glide bearings and a roll including glide-bearings. The roll mantle is supported on a stationary roll axle by hydraulic glide-bearing members acting upon the roll mantle or upon the roll ends. The bearing members are loaded hydraulically by a pressure medium. The roll mantle is supported on the roll axle by at least one pair of glide-bearing members which acting radially and/or axially in opposite directions. When an outside force that shifts or attempts to shift the roll mantle in the direction transverse to the main loading direction and/or in the axial direction is applied to the roll mantle, the pressure in the glide-bearing member placed at the side of the higher loading is adjusted to a level higher than the pressure in the glide-bearing member acting in the opposite direction so that the outside forces are neutralized. In another embodiment, the roll mantle is permitted to be shifted over a certain distance in the main loading direction. When the roll mantle approaches its preset extreme position in this direction, the movement of the roll mantle is brake down, and finally the movement is stopped in its extreme position by the glide-bearing members.

摘要： Method and device in a press section of a paper machine for detaching a web from a smooth face of a press roll. Momentary and local heating effect is directed at the web from outside the roll within the area or vicinity of a detaching point thereof. Material is used as the mantle or outer coating of the smooth-face roll which is at least somewhat magnetically conductive. An inductive heating effect is applied to the roll mantle free of contact therewith, and of such a high frequency, that depth of penetration of the heating effect remains sufficiently low in view of the local and momentary nature. Due to this heating effect, water present between the web and roll face is heated, even vaporized locally within the area of the detaching point, thereby detaching the web from the roll face. The electrical frequency of the induction heating is generally within the range of about 0.5 to 2 mHz, preferably within the range of about 0.8 to 1.5 mHz.

摘要： Method in an adjustable-crown roll, in which a series of hydraulic loading elements is used. A central axle of the roll is supported by axle journals, by means of deflection bearings. A cross-section of the central axle is shaped such that the axle has sufficiently high rigidity in a nip plane. In the method, the central axle is rotated about its deflection bearings over an angle, which may be within the range of about 30.degree. to 180.degree.. A free space that is created or enlarged between the central axle and a roll mantle thereby, and provided between the central axle and an inner surface of the roll mantle, is utilized as an opening gap for the nip formed by the variable-crown roll, by allowing the roll mantle to be shifted, e.g. by the effect of gravity, or by affirmatively shifting the mantle relative to the rotated central axle.

摘要： A method and apparatus for supporting a roll mantle of a roll for a paper machine or equivalent in a lateral direction, in particular in the direction transverse to a principal loading direction, such as the nip plane. The roll mantle is rotatingly supported on a stationary roll axle, e.g., by support and loading members, and is displaceable in relation to the axle substantially in the principal loading direction. The roll mantle is also supported on the roll axle radially by glide bearing elements acting in opposite radial directions so that, when the roll mantle is displaced in the principal loading direction, the movement of the roll mantle is guided to take place along a predetermined path.
