ABSTRACT:
The present invention provides a method for creating uniform pressure at a nip comprising the acts of providing a stationary inner core, pivotally mounting a plurality of shoes to the stationary inner core, creating a plurality of annular chambers wherein each of the shoes occupies one of the chambers. In addition, the method further provides filling each of the chambers with a magneto-rheological fluid, surrounding the plurality of chambers, shoes, and stationary inner core with a thin, metal, rotatable shell; detecting a deformation in the shell and changing a magnetic field in at least one of the chambers to change a viscosity of the magneto-rheological fluid to correct the deformation.
