Abstract (en)
[origin: EP1484444A1] In a twin wire former, white-water withdrawal means (20) for withdrawing white water (15) dewatered to the opposite side of a roll is arranged to the upstream side of a pressure element (30) to suppress the interference of the dewatered white water (15) with the pressure element (30). This renders it possible to prevent damage to the pressure element (30) that is caused by a collision with white water (15) during dewatering and to manufacture defect-free paper that has even dispersion of fibers. <IMAGE>
