ABSTRACT:
A paper-making machine roll press or mill comprising a suction press roll over which there is trained a press felt, and which simultaneously serves for the direct transfer of a web of paper from a wire. A take-off press roll cooperates with the suction press roll to form a press station. The take-off press roll serves for the transfer of the paper web from the suction press roll and for the delivery thereof to a downstream part of the paper-making machine. An additional press station is provided between the suction press roll and the take-off press roll and is formed by a contact-pressure roll over which there is trained a felt. The contact-pressure roll comprises a hydrostatic flexure adjusting or controlled deflection roll having a shell mounted to be rotatable about its lengthwise axis and displaceable in the press direction relative to a fixed or stationary support.
