  • Patent number: 5645691
    Abstract: The invention provides a roll for a papermaking machine, comprising at least one strip element which extends substantially in the axial direction of the roll and which is supported, substantially against radial forces, by a plurality of supporting elements. The supporting elements comprise adjusting means by means of which a predetermined profile of the bending curve of the strip element can be adjusted in response to a given outer load. When the roll is configured as a shoe press roll, then the strip element may also be directly coupled with the press shoe. It is possible in this way, in the case of shoe press rolls, to ensure safe development of a hydrodynamic lubricating wedge and, in the case of other rolls, to adjust a desired profile of the bending curve of the strip element, under a given outer load.
