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.
