PRESSING ARRANGEMENT IN THE PROCESSING APPARATUS OF A PAPER/BOARD MACHINE OR FINISHING MACHINE WITH A METAL BELT LOOP

摘要

The invention relates to a pressing arrangement in the processing apparatus (1) of a paper/board or finishing machine with a metal belt loop. The fibrous web (W) to be processed is led through a nip (N) formed by the belt loop (2) and a counter-element (5) outside it, where the fibrous web is subjected to pressing action in the processing zone between the metal belt and the counter-element and a local additional load within the said processing zone by means of at least one pressing element inside the belt loop. The internal pressing element in the metal belt loop is a load beam (40) to which a support roll (41) is rotatingly fitted in bearings by means of a hydrodynamic bearing system, which support roll can be brought into contact with the inner surface of the metal belt loop (2) for exerting the local additional load force on the fibrous web (W) being processed.
