摘要： The invention concerns variable contour rollers for use in calendering or pressing devices, printing presses and like applications. The rollers include an external element of cylindrical form, for example of cast iron, and in their interior a number of transverse elements which can be made to expand radially by heating. More or less substantial radial expansion provokes directly or indirectly a change in the profile of the exterior generally cylindrical working surface. The interior of the roller may be a shaft carrying heating elements and which is fixed or rotates with the external working surface.

摘要： A roller used as a press or calender roller in a paper machine is compensated for deflection and end-loaded. The roller has a stationary axle with spaced opposite ends at which the roller is loaded and a cylindrical shell rotatably mounted on the axle. The axle has a magnetic core portion within the shell having pole shoes spaced from the shell by air gaps and magnetizing coils of electrical conductors thereon at corresponding ones of the pole shoes. The coils produce a magnetomotive force and are positioned in a manner whereby magnetic flux passing through the air gaps between the pole shoes and the shell creates a compensating force field between the shell and the magnetic core. The roller has an inner part of the shell consisting of a stack of sheets of magnetically well-conductive material separated from each other by electrical insulation thereby reducing eddy current losses.

摘要： A controlled deflection roll wherein the individual pressure or support elements thereof have operatively correlated thereto springs which act in addition to the pressure force exerted by the pressure or support elements. At the same time there are provided external pressing or contact devices which exert a predetermined pressing or contact force. These pressing devices, in the work position of the controlled deflection roll, bring about a force equilibrium in conjunction with the pressure or support elements and the springs.

摘要： A calender roll has a hollow cylinder which surrounds or is surrounded by a stationary support. That surface of the support which faces the cylinder has circumferential and axially parallel grooves for the coils of electromagnets which are energizable independently of each other or simultaneously and serve to prevent flexing and/or other deformation of the cylinder when the latter rotates and contacts a running web of paper, textile material or metallic or plastic foil. Those sections of the aforementioned surface of the stationary support which are surrounded by the coils constitute portions of circumferentially extending arcuate or annular pole faces and the polarity of each circumferentially extending pole face is constant. However, the polarities of neighboring pole faces the different, i.e., pole faces which constitute south and north poles alternate with each other, as considered in the axial direction of the calender roll. The cylinder can be subjected to controlled heating action by splitting the circumferentially extending pole faces, by connecting some or all of the coils to sources of a-c current, by varying the extent of excitation of the coils and/or by a combination of two or more of these methods.

摘要： A roller, in particular an expander roller, for a web-processing machine, has a support core, which is braced in the region of both its ends via a respective bearing arrangement, and an outer covering, which in its axially central region is braced in a radially fixed manner in relation to the support core and in the region of its two ends is braced in a radially displaceable manner in relation to the support core by a respective additional bearing arrangement, whereby the radially extending center plane of both the support core bearing arrangement and the outer covering bearing arrangement lies axially within the outer covering. Preferably the outer covering is displaceable in this case in the region of its two ends respectively by an actuator arranged within the outer covering.

摘要： Deflection adjustment roll and process for supporting a roll jacket on a crosspiece of the deflection compensation roll. The deflection compensation roll includes a crosspiece, roll bearings composed of radial bearings and at least one hydrostatic bearing arrangement, and a roll jacket, which is rotatably supported on the crosspiece by the roll bearings. The at least one hydrostatic bearing arrangement acts in the axial direction. The process includes positioning radial roll bearings each bearing end of the deflection compensation roll and between the crosspiece and the roll jacket, wherein the radial roll bearings absorb radial forces, and positioning at least one hydrostatic bearing arrangement between the crosspiece and the roll jacket, wherein the at least one hydrostatic bearing arrangement absorbs axial forces.
