Abstract

Die Erfindung betrifft einen Doppelsiebformer (1) einer Maschine zur Herstellung einer Faserstoffbahn aus mindestens einer Faserstoffsuspension (2), mit zwei in jeweiliger Siebschlaufe (5, 6) umlaufenden endlosen Sieben (3, 4), die zumindest streckenweise eine Doppelsiebzone (7) bilden, wobei in Sieblaufrichtung (S) des ersten Siebs (3) vor der Doppelsiebzone (7) eine Vorentwässerungsstrecke (8) ausgebildet ist, in welcher ein Stoffauflauf (9) zur Aufbringung der mindestens einen Faserstoffsuspension (2) auf das erste Sieb (3) und mindestens ein Entwässerungselement (10) zur Entwässerung der mindestens einen auf dem ersten Sieb (3) aufgebrachten Faserstoffsuspension (2) angeordnet sind.The invention relates to a twin-wire former (1) of a machine for producing a fibrous web from at least one pulp suspension (2), with two endless screens (3, 4) circulating in respective screening loops (5, 6) which at least partially form a twin-wire zone (7) , wherein in the wire direction (S) of the first sieve (3) in front of the twin-wire zone (7) a pre-dewatering section (8) is formed in which a headbox (9) for applying the at least one pulp suspension (2) to the first wire (3) and at least one dewatering element (10) for dewatering the at least one fibrous suspension (2) applied to the first wire (3).

Der erfindungsgemäße Doppelsiebformer (1) ist dadurch gekennzeichnet, dass eingangsseitig der Doppelsiebzone (7) eine vorzugsweise alleinstehende und in der Höhe vorzugsweise positionierbare Skimmereinrichtung (11) in der Siebschlaufe (6) des einen, vorzugsweise zweiten Siebs (4) angeordnet ist, dass der Skimmereinrichtung (11) in Sieblaufrichtung (S) wenigstens ein Stützkasten (12) zur Führung der beiden Siebe (3, 4) mit dazwischen liegender Faserstoffsuspension (2) in der Siebschlaufe (5) des anderen, vorzugsweise ersten Siebs (3) nachgeordnet ist und dass gegenüber dem wenigstens einen in der Siebschlaufe (5) des anderen, vorzugsweise ersten Siebs (3) angeordneten Stützkasten (12) mindestens eine weitere vorzugsweise alleinstehende Skimmereinrichtung (13) in der Siebschlaufe (6) des einen, vorzugsweise zweiten Siebs (4) angeordnet ist.
