ABSTRACT:
The belt press unit of a paper machine includes an elastic tubular press belt which passes around the circumference of and is spaced from the surface of a hollow, annular supporting body. A press shoe in the supporting body presses outwardly and urges the press belt against an opposing surface on a mating roller for defining a press nip. Circumferentially outside of the press zone, each of a plurality of circumferentially spaced guide ledges extends across the direction of travel of the belt. A torsionally rigid beam extends through and is attached at two axially spaced locations along the hollow of the annular supporting body. At least one of the guide ledges is supported to the beam, whereby radial deflection of the supporting body does not result in radial deflection of the beam and thus does not cause radial shifting of the guide ledge. The beam is axially displaceable with respect to the supporting body. The ledge is supported on stay bolts which are guided by wedge-shaped supporting surfaces on the beam. These surfaces shift the stay bolts and thereby shift the ledges radially as the beam shifts axially with respect to the supporting body.
