摘要： The invention relates to a twin wire former for the production of a fiber web specifically a paper, cardboard or tissue web, from a fiber suspension. The invention is characterized in that the rotating forming roll has an open volume and is a non-suction type; the rotating forming roll has a forming roll diameter of less than 1,400 mm; the rotating forming roll has a forming roll angle of wrap of less than 70°; a forming suction box is located immediately downstream from the rotating forming roll as viewed in direction of wire travel; and in the area of the wedge-shaped inlet nip, the fiber stock suspension has a stock density of between 0.4% and 2.0%, preferably between 0.6% and 1.5%. These characteristics result in an improved forming quality and web quality.

摘要： A wet section (10) of a paper or cardboard machine and a process for the manufacture of a fibrous material web are suggested. The wet section (10) exhibits a double-screen segment (US), in which two screens (16, 18) are guided about parallel to one another and into which a fibrous material suspension (27) is introduced. The double-screen segment (US) is looped around a roll (22). The means (30, 32, 38) for the immobilization of the fibrous material suspension in the double-screen segment (US) are provided on the roll (22), for the formation of the fibrous material web. Moreover, the wet section exhibits means (32, 34, 36; 34, 36, 66) for further draining of the fibrous material web. The roll (22) is thereby a combined forming and draining roll (22), which exhibits a forming sector (FS), on which the immobilization means (30, 32, 38) are arranged, as well as a draining sector (ES) located in the direction of the running screen behind the forming sector (FS), on which at least a predominant part of the draining means (32-36; 34, 36, 66) is arranged.
