Abstract

Die Erfindung betrifft eine Presseneinrichtung (1) mit einer Saugpresswalze (5, 26). Dabei kann eine Linienkrafterhöhung in Presseneinrichtungen (1) mit Saugpresswalzen (5, 26) gleicher oder geringerer Größe als konventionelle Saugpresswalzen erzielt werden, indem die Saugpresswalzen mit einem Durchbiegungsausgleich ausgestattet werden. Dieser ist parallel zur Längsachse (L) der Saugpresswalze (5, 26) in dieser angeordnet. Je nach Walzenmantelausführung und Anordnung des Saugkastens (12) sind unterschiedliche Konzepte möglich, wobei die eine erste Ausführung durch die Integration einer Schuhpresswalze (6) in der Saugpresswalze (5) charakterisiert ist. Eine zweite Ausführung ist durch die Kombination einer Führung von Verbindungskanälen zwischen Pressspalt (4) und Saugkasten durch den Walzenmantel (27) mit integriertem Durchbiegungsausgleich im vom Walzenmantel (27) umschlossenen Innenraum (33) charakterisiert.

The invention relates to a press device (1) with a suction press roll (5, 26). In this case, a line force increase in press devices (1) with suction press rolls (5, 26) of the same or smaller size than conventional suction press rolls can be achieved by equipping the suction press rolls with a deflection compensation. This is parallel to the longitudinal axis (L) of the suction press roll (5, 26) arranged in this. Depending on the roll shell design and arrangement of the suction box (12), different concepts are possible, wherein the first embodiment is characterized by the integration of a shoe press roll (6) in the suction press roll (5). A second embodiment is characterized by the combination of a guide of connecting channels between press nip (4) and suction box through the roll shell (27) with integrated deflection compensation in the roll shell (27) enclosed interior (33).
