Abstract (en)
[origin: EP0496073A1] The invention relates to a twin-wire former in which the forming turbulence of a first forming region (F1) is abated by a main forming roll (26). A further forming process in a second forming region (F2) follows behind the main forming roll. Optimum forming with little dilution water is possible with this arrangement. In addition, flocculations which can arise in the region of the main forming roll can be eliminated from both the suspension and the web by intense shear forces in the second forming region, so that the web structure is made uniform. <IMAGE>
