Verfahren zur Herstellung von Pressplatten
Das den Gegenstand des Patentes Nr. 250 656 bildende Verfahren ist die Herstellung von aus einer oder mehreren Schichten bestehenden Pressplatten mit mindestens einer veredelten Oberfläche, beispielsweise Sperrholzplatten und vorzugsweise solchen, die aus mit Bindemittel beharzten, faserhaltigen Teilchen unter Wärme und Druck zusammengepresst werden, wie Holzspan-, Flachsspan-, Bagasseod. -platten, auf deren zu veredelnde Oberfläche vor dem Pressvorgang mindestens eine sich auf dem Zulageblech befindliche harzhaltige Deckfolie, wie eine Papier-, Textil-od.
dgl.-folieaufgebrachtund zusammen mit der späneschüttung in einem Arbeitsgang verpresst wird, gemäss dem die beidseitig harzgetränkten Folie mit einem Feuchtigkeitsgehalt von mehr als 20tao im harznassen Zustand zusammen mit der Spänemasse heissverpresst wird.
Infolge dieser Verwendung harznasser Folien besitzt dieses Verfahren den Vorteil, dass das einstufig durchzuführende Verfahren ohne Rückkühlung der Heisspresse durchführbar ist und damit also bedeutend wirtschaftlicher ist wie das Zweistufenverfahren, da mit den normalen Presszeiten, die sonst für eine unbeschichtete Platte benötigt werden, bereits eine fertige Dekorplatte erhalten wird.
Eine Verbesserung der Dekoroberfläche wurde bei diesem Verfahren noch dadurch erreicht, dass man zwischen die beleimten Späne und die harznasse Folie eine Schicht aus beleimtem Holzschleifstaub oder beleimten Sägespänen einbringt, welche Stoffe bisher nur zur Herstellung feinerer Oberflächen von geschliffenen, unbeschichteten Spanplatten verwendet wurden.
. Eshatsichnungezeigt, dassbeidemdenGegenstanddesStammpatentesbildendenVerfahreneinem Durchdrücken der Pressmasse in die Veredelungsschicht noch wirksamer dadurch begegnet werden kann, dass auf die der Pressmasse zugewendete Seite der Beschichtungsfolie eine, diesem Durchdrücken der Pressmasse entgegenwirkende elastische Zwischenlage durch Beflockung mit beleimten oder unbeleimten Cellulose-, Kunststoff-od. dgl. Fasern aufgebracht wird, wodurch sich die besondere Aufschüttung einer

platten verwendbar ist, genügt für letztere eine Aufrauhung deren Oberfläche durch Zerfasern derselben, wodurch gleichfalls eine elastische Unterlage für die Beschichtungsfolie geschaffen wird.

Process for the production of press plates
The process forming the subject of patent no.250,656 is the production of pressed boards consisting of one or more layers with at least one finished surface, for example plywood boards and preferably those which are pressed together under heat and pressure from fiber-containing particles resinated with binder, such as Wood chip, flax chip, bagasseod. -Plates, on the surface to be finished before the pressing process at least one resin-containing cover sheet on the additional sheet, such as a paper, textile od.
The like film is applied and pressed together with the bulk of chips in one operation, according to which the film, which is resin-soaked on both sides and has a moisture content of more than 20 tao, is hot-pressed together with the chip mass when it is wet with the resin.
As a result of this use of resin-wet foils, this process has the advantage that the process to be carried out in one step can be carried out without recooling the hot press and is therefore significantly more economical than the two-step process, since with the normal pressing times that are otherwise required for an uncoated panel, a finished panel is already available Decorative panel is obtained.
An improvement in the decorative surface was achieved in this process by inserting a layer of glued wood dust or glued sawdust between the glued chips and the resin-wet film, which materials have previously only been used to produce finer surfaces of sanded, uncoated chipboard.
. It has shown that in the method forming the subject of the parent patent, a pressing of the molding compound into the finishing layer can be counteracted even more effectively by providing an elastic intermediate layer on the side of the coating film facing the molding compound, counteracting this penetration of the molding compound, by flocking with glued or unglued cellulose, plastic or plastic. Like. Fibers is applied, creating the special embankment of a
EMI1.1
Plates can be used, it is sufficient for the latter to roughen their surface by fraying them, which also creates an elastic base for the coating film.
