  • Patent number: 4815183
    Abstract: In a controlled deflection roll, hydrostatic support elements are used which can be tilted to an increased extent only in the axial direction but not in the circumferential direction of the roll shell. Deflection or bending of the stationary support member, on which the roll shell is supported by the hydrostatic support elements is compensated by the axial tilting capacity of such hydrostatic support elements. The transverse forces occurring during operation of the controlled deflection roll are automatically compensated by the supporting directions or direction of action of at least outer bearing pockets of the hydrostatic support elements and which form a predeterminate angle with the pressing direction, so that force components directed in the circumferential direction are formed which substantially counteract the prevailing transverse force.
