Abstract

Die Erfindung betrifft einen Schrägsiebformer (1) einer Maschine zur Herstellung einer Faserstoffbahn (2), insbesondere einer Langfaserpapier- oder Nassvliesbahn, aus wenigstens einer Faserstoffsuspension (3) mit einem Sieb (4), welches über einen Umfangsbereich (6) einer Brustwalze (5) läuft und anschließend in Sieblaufrichtung (S) zumindest streckenweise unter einem vorzugsweise schrägen Winkel (α) zur Horizontalen (H) verläuft, wobei in diesem vorzugsweise schrägen Streckenabschnitt (7) des Siebs (4) mindestens ein Stoffauflauf (8) die wenigstens eine Faserstoffsuspension (3) oberseitig auf das Sieb (4) aufbringt, wobei unterseitig des Siebs (4) mindestens ein Entwässerungselement (9) zur Entwässerung der mindestens einen auf das Sieb (4) aufgebrachten Faserstoffsuspension (3) angeordnet ist und wobei das als Saugkasten (10) ausgebildete Entwässerungselement (9) zu dem Sieb (4) hin offen ist, um auf das Sieb (4) und die wenigstens eine auf dem Sieb (4) oberseitig aufgebrachte Faserstoffsuspension (3) eine Saugwirkung auszuüben, und mehrere das Sieb (4) berührende und zueinander beabstandete Entwässerungsleisten (11) aufweist, die sich quer zu der Sieblaufrichtung (S) erstrecken und mehrere Saugschlitze (12) begrenzen.
Der erfindungsgemäße Schrägsiebformer (1) ist dadurch gekennzeichnet, dass wenigstens ein Saugschlitz (12) des Saugkastens (10) in den beiden Randzonen (RR, RL) des Siebs (4) mit je einer verschiebbaren Zwischenleiste (18) versehen ist, die jeweils zwischen den beiden benachbarten Entwässerungsleisten (11) dichtend eingepasst ist, wobei die Zwischenleisten (18) eines Saugschlitzes (12) gemeinsam eine Saugzonen-Breite (BZ) bestimmen, die kleiner als die Breite (B4) des Siebs (4) ist.
