Abstract

Eine Streustation (1) zum Streuen von beleimten Streugütern, insbesondere Holzspänen, im Zuge der Herstellung von Holzwerkstoffplatten (8), mit einem Dosierbunker (2) zum Austragen der beleimten Streugüter, einer anschließend angeordneten Streukopfanordnung (4), die eine Aufgabe (A1) und ein Austragsende aufweist, und die mehrere parallel zueinander verlaufende Streuwalzen (6) aufweist, wobei in die Streuwalzenoberfläche Nuten (11) eingebracht sind, durch die zwischen benachbarten Streuwalzen (6) Streuspalte gebildet werden und wobei unterhalb der Streukopfanordnung (4) ein kontinuierlich bewegtes Formband (5) angeordnet ist, soll derart weitergebildet werden, daß sowohl eine ideale homogene Streuung, als auch eine separierte Streuung mit über den Querschnitt gleichmäßigen Streuergebnis erzielt werden kann. Dies wird dadurch erreicht, daß mindestens in jede zweite Streuwalze (6) Nuten (11) eingebracht sind und daß die Nuten (11) um die Streuwalzenoberfläche angeordnete umlaufende in sich geschlossene Nuten (11) sind, die zumindest in Teilabschnitten einen Winkel zu einer senkrecht auf der Längsachse (13) der Streuwalzen stehenden Ebene (12) aufweisen, und wobei die Nuten (11) parallel zueinander angeordnet und über die gesamte Länge der Streuwalzen (6) eingebracht sind.

Figure 00000001
A scattering station (1) for spreading glued spreading material, in particular wood chips, in the course of the production of wood-based panels (8), with a dosing bunker (2) for discharging the glued spreading material, a subsequently arranged spreading head assembly (4) having a task (A1) and a discharge end, and having a plurality of mutually parallel scattering rollers (6), wherein in the scattering roller surface grooves (11) are introduced, through which between adjacent scattering rollers (6) scattering gaps are formed and wherein below the scattering head assembly (4) is a continuously moving Forming band (5) is arranged, should be developed such that both an ideal homogeneous scattering, as well as a separate scattering can be achieved with over the cross section uniform scattering result. This is achieved in that at least in every second scattering roller (6) grooves (11) are introduced and that the grooves (11) arranged around the scattering roller surface circumferential self-contained grooves (11) which at least in sections at an angle to a perpendicular on the longitudinal axis (13) of the scattering rollers standing plane (12), and wherein the grooves (11) arranged parallel to each other and over the entire length of the scattering rollers (6) are introduced.
