Abstract: The invention is directed to a paper machine including a headbox having an inlet and an outlet. A fluid conduit is connected to the inlet of the headbox. A sensor is disposed in communication with an interior of the headbox. The sensor senses a pressure of the fiber suspension within the headbox and provides a signal corresponding thereto. A first pump is connected to the fluid conduit and supplies a fiber suspension to the headbox through the fluid conduit. A second pump is connected to the fluid conduit between the first pump and the headbox, and further is connected to the sensor. The second pump is a substantially pulseless pump, and transports the fiber suspension away from the fluid conduit, dependent upon the sensed signal.

Abstract: A cross beam in a papermaking machine frame, having a specific overall length is composed of three nested beam elements, namely an outer beam element, a middle beam element and an inner beam element. The middle beam element is at its one end rigidly connected with the outer beam element and on its other end with the inner beam element. The material of the middle beam element, for instance aluminum, has approximately twice the coefficient of thermal expansion as compared to the material of the other beam elements, for instance steel. Therefore, the overall length of the beam remains essentially unchanged if a temperature change entails a length change of the beam elements.

The two positioning devices pivot the roll mounting frame about the pivot axis and thereby move the roll in one of the transverse directions. The two positioning devices coact to maintain the roll mounting frame in one of a plurality of positions relative to the support frame.
