Abstract

Vorrichtung zum Streuen von beleimten Streugütern, insbesondere span- und faserförmige Güter, im Zuge der Herstellung von Holzwerkstoffplatten, mit einem Dosierbunker zum Austragen der beleimten Streugüter, auf eine Auflösewalzenanordnung, die zumindest zwei gegensinnig rotierend benachbart angeordnete, mit Auflöseelementen versehene Walzen, umfasst und mit einer anschließend angeordneten Streuwalzenanordnung, durch die das Streugut auf ein Formband aufstreubar ist, soll derart weitergebildet werden, dass eine qualitativ hochwertige Holzwerkstoffplatte hergestellt werden kann, wobei beim Streuen insbesondere eine unkontrollierte Umverteilung des Streugutes in Querrichtung vermieden werden soll. Dies wird dadurch erreicht, dass unmittelbar der Auflösewalzenanordnung (3) nachgeschaltet ein Beruhigungsfächer (4) angeordnet ist, der aus mehreren in Förderrichtung nebeneinander angeordneten längs zur Förderrichtung sich erstreckende Wandelemente (11) besteht, wobei die Wandelemente (11) eine Vielzahl von Beruhigungskammern (12) bilden.

Figure 00000001
Device for spreading glued spreading goods, in particular chip and fibrous goods, in the course of the production of wood-based panels, with a dosing bunker for discharging the glued spreading material, on an opening roller assembly, the at least two oppositely rotating adjacent arranged, provided with release elements rollers, and with a subsequently arranged scattering roller arrangement, by which the spreading material is aufstreubar on a forming belt, should be further developed such that a high quality wood-based panel can be produced, in particular an uncontrolled redistribution of the material to be spread in the transverse direction should be avoided during spreading. This is achieved by arranging directly downstream of the opening roller arrangement (3) a calming compartment (4) which consists of a plurality of wall elements (11) arranged side by side in the conveying direction and extending longitudinally with respect to the conveying direction, the wall elements (11) having a plurality of calming chambers (11). 12) form.
