Description
Die Erfindung nach dem Hauptpatent 857 928 bezieht sich auf ein Verfahren und- eine Vorrichtung zur Vermeidung von Wellen und Rissen beim Trocknen von Furnieren, nach dem die quer zur Faser liegenden Randzonen. der Furniere während des Trockenvorganges mittels .parallel zum abzudeckenden Rand des Furniers verlaufender Leisten abgedeckt werden, von denen eine auf der Oberseite, die andere auf der Unterseite des jeweiligen Randes der Furnierplatte aufliegt. Mit der vorliegenden Erfindung wird eine Erweiterung des Anwendungsgebietes der Erfindung nach dem Hauptpatent bezweckt.The invention according to the main patent 857 928 relates to a method and - a device to avoid waves and cracks when drying veneers, after which the edge zones lying across the grain. of the veneers during the drying process covered by means of strips running parallel to the edge of the veneer to be covered of which one on the top, the other on the bottom of each The edge of the veneer board rests. The present invention is an extension the scope of the invention according to the main patent.
Die Erfindung besteht darin, daß die Leisten bei Verwendung in einem Rollentrockner aus dünnen Platten aus Metall, Kunststoff öd. dgl. bestehen, deren Abstand voneinander mittels Zwischenstücken größer gehalten ist als die Dicke der zwischen den Leisten eingelegten, Furnierplatten. Das hat den Zweck, der eingelegten Furnierplatte einen gewissen Spielraum für eine freie Beweglichkeit zu lassen, damit in der Platte etwa enthaltene Stammrisse nicht deformiert werden.. Zweckmäßig sind je zwei Metalleisten mittels Federbügel zusammengehalten. Hierdurch wird das Einlegen der Furniere in die Leisten -und das Einführen der Leisten mit den eingelegten Furnierplatten in den Rollentrockner erleichtert. Vorteilhaft sind ferner die äußeren Kanten der Leisten oben- und unterhalb der Zwischenstücke mit Auflagen versehen, auf denen die Rollen des Rollentrockners aufliegen. Hierdurch wird, eine sichere Führung der Rollen auf den Leisten erreicht, ohne daß die Leisten an ihren inneren. Kanten zusammengedrückt werden, wodurch die eingelegte Furnierplatte ihre freie Beweglichkeit verlieren würde. Zweckmäßig sind die Leisten mit auf ihrer gesamten Länge verteilten Löchern, od. dgl: versehen.The invention is that the strips when used in a Roller dryer made of thin sheets of metal, plastic or Like. exist, whose Distance from one another is kept greater than the thickness of the spacers Veneer panels inserted between the strips. That has the purpose of the pickled Veneer panel to leave a certain leeway for free movement, so Any trunk cracks contained in the plate are not deformed .. Are expedient Two metal strips each held together by means of spring clips. This will make the insertion the veneers in the strips - and the introduction of the strips with the inserted veneer panels eased into the roller dryer. The outer edges of the Provide strips above and below the intermediate pieces with supports on which the rollers of the roller dryer are on top. This is a safe management of the Rolls on the ledges achieved without the ledges being attached to their interior. Edges pressed together as a result of which the inserted veneer panel loses its freedom of movement would. The strips with holes distributed over their entire length are useful, or the like: provided.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.
Abb. i ist eine Draufsicht auf ein Furnierblatt mit seitlichen Abdeckleisten; Abb. 2 ist eine Ansicht auf die in Faserrichtung liegenden, Kanten des Furnierblattes, -wobei die Leisten im Querschnitt gezeigt sind.Fig. I is a plan view of a veneer sheet with side cover strips; Fig. 2 is a view of the grain direction edges of the veneer sheet, -wherein the strips are shown in cross-section.
Mit i ist ein Furnierblatt bezeichnet, das zwischen den Leisten 2 eingelegt ist. Die Leisten 2 bestehen aus zwei dünnen Platten aus Metall oder Kunststoff. Ihr Abstand voneinander ist mittels der Zwischenstücke 3 größer gehalten als die Dicke der zwischen den Leisten :2 eingelegten-Furnierplatte i, um den gewünschten. Spielraum für die Furnierplatte i zu erhalten. Je zwei Leisten 2 sind mittels eines federnden Bügels 4 zusammengehalten,. Außerdem sind die äußeren Kanten der Leisten, 2 Oberun.d unterhalb der Zwischenstücke 3 mit Auflagen 6 versehen, auf denen die Rollen des Rollentrockners aufliegen, die nicht weiter dargestellt sind. Die Leisten 2 können mit auf ihrer gesamten Länge verteilten Löchern 7 versehen sein. Bei der Leiste 2 auf der einen Seite der Abb. i besteht der federnde Bügel ¢ aus einem durchgehenden. Stück, während auf der anderen Seite der Abb. i gezeigt ist, wie dieser federnde Bügel auch aus mehreren einzelnen Bügeln 5 bestehen kann.A veneer sheet is denoted by i, which between the strips 2 is inserted. The strips 2 consist of two thin plates made of metal or plastic. Their distance from one another is kept greater than that by means of the spacers 3 Thickness of the veneer panel inserted between the strips: 2 to the desired. To get leeway for the veneer panel i. Every two strips 2 are by means of one resilient bracket 4 held together. In addition, the outer edges of the strips, 2 Oberun.d below the intermediate pieces 3 provided with supports 6 on which the Rollers of the roller dryer that are not shown any further lie on top. The bars 2 can be provided with holes 7 distributed over their entire length. In the Bar 2 on one side of Fig. I, the resilient bracket ¢ consists of a continuous one. Piece, while on the other side of Fig. I it is shown how this resilient Bracket can also consist of several individual brackets 5.
