Fourdrinier table

A fourdrinier table assembly of a length to underlie a substantial portion of the forming length of a travelling fourdrinier wire in a paper making machine, and comprising:

• a supporting structure adapted to be located below said forming length portion and including a plurality of spaced beams arranged to extend in cross machine direction supportingly under said rails and having means for securing opposite end portions of the beams to a machine frame;
• a plurality of supporting rails carried by and extending across said beams in side-to-side spaced relation to one another and arranged to span said forming length portion in machine direction below said fourdrinier wire;
• a series of elongate dewatering foils carried by and extending in cross machine direction across said supporting rails in spaced relation to one another along the length of said rails and adapted to act in dewatering relation with respect to the underside of the traveling fourdrinier wire;
• and means for retaining said foils adjustably and replaceably on said rails.
