ABSTRACT:
A frame structure for calenders in a paper machine in which two vertical legs are horizontally connected to one another. The calender rolls are mounted, one above the other, between the vertical legs so that the upper roller is fixed vertically while the lower roller is able to slide vertically. A loading cylinder is used to move the lower cylinder vertically within the frame. The loading cylinder is mounted on a beam structure which is attached at its ends to the inner walls of the frame legs. The beam structure is shaped so that it is able to flex or pivot relative to the frame's legs so that only vertical forces are transmitted to the frame and transmission of bending moments from the beam structure to the frame structure and the foundation is substantially eliminated.
