Abstract

Ein Streckwerk (1) zum Verziehen eines Stapelfaserverbandes (8) enthält wenigstens zwei antreibbare Unterwalzen (4, 6) und daran andrückbare Oberwalzen (5, 7, 13) sowie mit einem Haltekörper (17) zum Halten wenigstens einer der Oberwalzen (7; 13). Die Oberwalze (7; 13) kann mit dem Haltekörper (17) ein Druckwalzenaggregat (18) bilden. Die Oberwalze (7; 13) enthält eine am Haltekörper (17) befestigte Achse (15; 16) und zumindest eine rotierbar auf der Achse (15; 16) gelagerte Hülse (19) mit einem vom Haltekörper (17) beabstandeten Bezug (20). Der Außenumfang der Achse (15; 16) ist auf seiner gesamten Länge zwischen dem Bezug (20) und dem Haltekörper (17) von einem Staubschutz (22) umschlossen, der bevorzugt um die Achse (15; 16) rotierbar ist.
