Abstract

Improvements in the apparatus for the continuous formation of a fibrous sheet, from a diluted paste material, comprising: a first closed, permeable, outer forming grid; a second closed, permeable, inner forming grid; said grids being positioned to form a converging groove leading to a forming section in which the grids press on a sheet that is forming in the space between them; a feeder drawer having an opening positioned to direct a stream of material into said throat; guide rollers, inside each of the closed grids, which keep the grids in tension, so that the outer grid applies in said forming section a compression force that oppresses the sheet located between the grids; a convexly curved surface, within the second grid, with the first and second grids wrapping said surface along said forming section; improvements characterized in that there is provided in the apparatus a first separating guide means (16), for said first grid (10), positioned after the forming section, which separates the first grid from the second grid (12), in the first separation point (14) of said curved surface (15); and a second separating guide means located after said forming zone (14), which, at a second separation point (35), separates the second grid separating it from said surface, said second separation point (35) being downstream of the first separation point (34), and with said curved surface (15) lacking perforations, at least in said separation pins.
