ABSTRACT:
A controlled deflection roll has a roll shell which is hydrostatically radially supported by internally disposed hydrostatic shoes. In order to axially position the roll shell, a mechanical locating link is provided which is disposed externally of the roll shell. The link is coupled at one end to an element attached to the roll shell, and is coupled at an opposite end to a fixed support, such as a floor stand. The end of the roll at which the locating link is disposed is thus axially fixed, while the opposite end of the roll remains free to float. The locating link can be connected to an oscillator to oscillate the roll shell axially during operation so as to distribute any non-uniformities in the roll shell and thus to mitigate their effect on the sheet.
