The composite of first and second wire (12, 13) and interposed web (W) is contacted with a first cover part (33; 331) of a special suction box (30). A roll (23) guiding the second wire (13), pressing from the side of the latter deflects its run. This pressure plus centrifugal force, and the differential pressure arising from the suction box (30), dewater the web (W). The second wire (13) is separated to follow along with the guide roll (23), while web (W) and first wire (12) are acted on by the suction box (30) vacuum. The first wire (12) is then contacted with a second cover part (34; 341, 342, 343, 344; 348, 349) of the suction box (30). A twin-wire former is also disclosed, featuring within its carrying wire loop (12), on its twin-wire nan, a rotating forming roll (15; 151, 152) deflecting the composite of wires (12, 13) and web (W) as it laps a given sector (ssF) of said forming roll (15; 151, 152). A special suction box (30) at the ultimate end of the wires (12, 15) has a bipartite cover its parts (33, 34) angulated against each other and preferably planar.,下面是PROCEDURE IN THE WIRE SECTION OF A PAPER MACHINE,AND TWIN-WIRE FORMER APPLYING THE PROCEDURE专利的具体信息内容。
