PCT No. PCT/GB94/01426 Sec. 371 Date Jan. 31, 1996 Sec. 102(e) Date Jan. 31, 1996 PCT Filed Jun. 30, 1994 PCT Pub. No. WO95/01221 PCT Pub. Date Jan. 12, 1995A method for the dewatering of a material layer of paper fibers in a double-screen former, where the sheet weight (oven-dried sheet weight (otro)) is more than 100 g/m2 and/or the screen circulates with a speed of at least 100 m/min. Two screens are guided at two guide surfaces that, for example, belong to open forming cylinders. In this arrangement forming cylinders of this kind are so dimensioned and positioned that no dewatering elements that contact one of the screens are present between the run-out line of the screens from the first guide surface and the run-in line at the second guide surface.
