ABSTRACT:
A twin-wire belt press is disclosed for dewatering a fiber suspension and forming a continuous web of the fiber suspension. The twin wire belt includes a plurality of upper and lower rolls, a perforated roll and endless upper and lower wire belts. Dewatering tables are used to support the endless upper and lower wire belts and form a wedge-shaped pressure space between the endless upper and lower wire belts for initially pressing and dewatering the fiber suspension and forming a web therebetween. Roll members, including at least two press rolls which form press roll nips with the perforated roll and another roll, press and dewater the web between the endless upper and lower wire belts.
