DISPOSITIVO DI STAMPAGGIO, IN PARTICOLARE PER SOSPENSIONI FIBROSE

The invention concerns a pressing device for the extrusion of liquids from sludge, underground works or suspensions with at least one assembly of three pressure rollers which form two pressure slits in which a belt or fabric is guided along the curved surface of the rollers, from one pressure slit to the other. The invention is characterised by the fact that in the travel direction of the belt or fabric, the first or last roller 2 is revolving with a pressing device 7 being adapted to it, by the fact that the third cylinder is fixed, that the conveyor system 14 of the adjustable arm 5 is found on the side of the contact plane of the mid-longitudinal axes of the first mobile roller and of the fixed roller, on which the second mobile cylinder 3 is found, or at least the corresponding main part, and by the fact that the angle formed between the contact plane between the axis of the support position 7 of the revolving arm 5 and the mid-longitudinal axis of the second mobile roller 3 and between the contact plane of the mid-longitudinal axes of the first mobile roller 2 and the fixed roller 9 on which is the adjacent side of the first mobile roller, is between 45 and 80 degree.
