Description

Vorrichtung zum Verleimen von Furnierstoßfugen mit einer zur Auflage der Brettchen dienenden erwärmbaren Unterlage und mit einem darüber befindlichen, ebenfalls erwärmbaren Druckbalken, welche beide senkrecht zur Brettchenfläche längs geteilt sind. Es ist in der Sperrholzfabrikation schwierig, fast unmöglich, größere astfreie und rissefreie Furnierplatten herzustellen. Es war daher. bisher üblich, gerissene Furniere aufzutrennen, bei ästigen Furnieren die eiste auszukneifen; hierauf wurden die Stoßkanten bearbeitet und alsdann die gefugten Furniere nebeneinandergelegt und die Fuge mit Papierstreifen überklebt, um zum Schluß in Platten gesperrt zu werden. Abgesehen davon, daß eine derartige Verarbeitung sehr mangelhaft ist, weil die auf diese Art übereinandergehefteten Furniere mit der größten Vorsicht behandelt werden müssen, um ein Zerreißen der Papierstreifen zu verhüten, ist diese Fabrikation umständlich, zeitraubend und kostspielig. Mit Rücksicht hierauf konnte es daher nur bei größeren Abmessungen in Frage kommen. Außerdem war die Fuge selten von einwandfreier Dichtigkeit. und verursachte es große Mühe, nach der Serrung die Papierstreife. von der Fuge zu entfernen.Device for gluing veneer butt joints with a support The heatable pad serving the board and with a also heatable pressure beam, both of which are perpendicular to the surface of the board are divided. It is difficult in plywood manufacture, almost impossible, larger ones Manufacture knot-free and crack-free veneer panels. It was therefore. usual up to now, to separate cracked veneers, to pinch out the edge of knotty veneers; on this the abutting edges were processed and then the jointed veneers were placed next to each other and pasted over the joint with strips of paper to finally lock it in panels will. Apart from the fact that such processing is very poor because handle the veneers stapled in this way with the greatest care must be in order to prevent the paper strips from tearing, is this fabrication cumbersome, time consuming and expensive. With that in mind, it could only come into question for larger dimensions. In addition, the joint was rarely flawless Tightness. and it caused great trouble, after the serrung the strip of paper. to remove from the joint.

In weiterer Ausbildung dieses Verfahrens wurde die Papierbeklebung dadurch vermieden, daß die mit Leim versehenen Stoßkanten unter Druck und Wärme aneinandergepreßt wurden, so daß eine Platte entsteht, die aus einzelnen hochkant aneinandergeleimten Furnierstreifen besteht. Bei einer solchen Maschinenbauart erfolgt die Pressung durch Druckwalzen. Es ist auch bekannt, die zu verleimenden Furnierstücke zwischen Metallplatten einzeln zu halten und gegeneinander zubewegen, wobei aber Papierbeklebung stattfand.In a further development of this process was the paper pasting thereby avoided that the butting edges provided with glue under pressure and heat were pressed together, so that a plate is formed, which is made of individual edgewise veneer strips glued together. In such a machine type the pressing by pressure rollers. It is also known the pieces of veneer to be glued to hold individually between metal plates and move towards each other, but Paper wrapping took place.

Die genannte Papierbeklebung ist bei der nachstehend beschriebenen Maschine vermieden, aber das Einspannen zwischen gegeneinanderbewegten Metallplatten beibehalten. Hierbei sind der Druckbalken und die Unterlage längs geteilt, wobei für möglichst vollkommene Haltung und Führung der zusammenzuleimenden Furnierkanten gesorgt ist. Dies wird dadurch erreicht, daß die einander gegenüberliegenden Flächen der Trennungsfuge des Druckbalkens und der Unterlage mit senkrecht zu diesen Flächen bzw. zu der Fuge ineinander verschiebbaren Verzahnungen versehen sind.The paper pasting mentioned is the one described below Machine avoided, but the clamping between moving against each other Metal plates maintained. Here, the pressure beam and the base are divided lengthways, with for the perfect holding and guidance of the veneer edges to be glued together is taken care of. This is achieved in that the opposing surfaces the separation joint of the pressure beam and the base with perpendicular to these surfaces or teeth that can be shifted into one another to form the joint are provided.

In der Zeichnung ist eine Ausführungsform wiedergegeben, und zwar zeigt Abb. i eine Seitenansicht, Abb. 2 einen Grundriß im teilweisen Schnitt und Abb.3 einen Querschnitt nach der Linie A-B der Abb. i.In the drawing, an embodiment is shown, namely Fig. i shows a side view, Fig. 2 shows a plan view in partial section and Fig.3 shows a cross-section along the line A-B in Fig. I.

Die übereinander angeordneten Druckbalken sind in gegeneinander verstellbare Glieder 1, 2, 3, 4 geteilt. Das Gegeneinanderklemmen dieser Teile erfolgt zweckmäßig durch mittels Kegelrädergetriebe 5, 6, 7, 8 bewegte senkrecht und wagerecht angeordnete Gewindespindeln 9, 1 o, i i, 12. Ihre Anzahl und Bauart ist völlig belanglos für den Schutzbereich und richtet sich nach der Größe und Leistungsfähigkeit der Maschine.The pressure bars arranged one above the other are adjustable in relation to one another Links 1, 2, 3, 4 divided. Clamping these parts against each other is expedient by means of bevel gears 5, 6, 7, 8 moved vertically and horizontally Threaded spindles 9, 1 o, i i, 12. Their number and type is completely irrelevant for the protection area and depends on the size and performance of the machine.

Sowohl die oberen Teile 1, 2 als auch die unteren Teile 3, 4 der Druckbalken sind durch Anordnung von Bohrungen 13, 14 heizbar.Both the upper parts 1, 2 and the lower parts 3, 4 of the pressure beam can be heated by arranging bores 13, 14.

Die einander gegenüberliegenden Flächen der oberen Teile 1, 2 der Druckbalken sind mit ineinanderschiebbaren Verzahnungen 15 versehen. Durch dieses In- und Aufeinandergreifen der Zahnformen ist ein sogenanntes Werfen beim seitlichen Gegeneinanderpressen der Furnierbrettchen ausgeschlossen und findet eine vollkommen einwandfreie dichte und feste Verleimung statt, wobei der Leim in dem Augenblick des Fließens gleichzeitig abbindet.The opposite surfaces of the upper parts 1, 2 of the Pressure bars are provided with teeth 15 that can be pushed into one another. Because of this The interlocking and overlapping of the tooth shapes is what is known as throwing when the teeth are on the side Pressing the veneer boards against each other is excluded and finds one perfect flawless dense and firm gluing in place, the glue being in the moment of flowing simultaneously sets.

Die Länge der Leimfuge sowie die der zu verleimenden Furniere ist unbegrenzt und richtet sich nach der Länge des Apparates.The length of the glue line as well as that of the veneers to be glued is unlimited and depends on the length of the device.

Durch das einfache und einwandfreie Arbeiten der neuen Vorrichtung wird sich die in Frage stehende Fabrikation nicht, wie bisher, auf größere Abmessungen beschränken, sondern vielmehr auch zur Herstellung kleinerer Deckplatten in Betracht kommen. Hierbei können sonst unverwendbare Abfälle verbraucht werden, was bei den heutigen Holzpreisen von wesentlicher Bedeutung ist.Because of the simple and flawless operation of the new device the production in question will not, as before, focus on larger dimensions limit, but rather also for the production of smaller cover plates into consideration come. Otherwise unusable waste can be consumed, which is the case with the Today timber prices is essential.
