Abstract

In order to glue saw-toothed abutting surfaces (1) of strip-shaped veneer pieces (2 and 3) to be joined to form veneer blanks, the front abutting surfaces (1) and hence the teeth (4) are in each case wetted with glue by arranging the two veneer pieces (2 and 3) at a distance from one another with one flat side and teeth (4) pointing towards one another on an application surface (7), an apportioned strip of glue (6) or, alternatively, a series of spots of glue being applied in the space between the two mutually facing front sides of these veneer pieces (2 and 3) to be joined, before, at the same time as their arrangement or, alternatively, afterwards, and at least one veneer piece then being moved towards the other and in the process being pushed through the glue with its teeth (4). In this process the moved veneer pieces(s) (2 and 3) is/are guided on their top side (10) facing away from the application surface (7) having the glue and are held down to such an extent that they are prevented from sliding over one another. The intermediate transport of the veneer blanks after the wetting of the abutting points with glue is thus avoided and the wetting with glue and the joining together take place on one and the same apparatus. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Verleimen gezahnter Stoßkanten von zu verbindenden Furnierstreifen, wobei jeweils Zähne des einen Furnierstückes in Zahnlücken des anzufügenden Furnierstückes eingeschoben und in dieser Position durch in der Fuge zwischen den beiden gezahnten Stoßkanten aufgetragenen Leim verbunden werden, wobei der Leim zunächst auf einer Auftrag-Fläche aufgetragen und wenigstens einer der Furnierstreifen dann über diese Auftrag-Fläche geschoben wird, wodurch seine stirnseitigen Stoßkanten mit Leim benetzt werden.The invention relates to a method for gluing toothed butt edges of veneer strips to be connected, wherein teeth of one piece of veneer are inserted into tooth gaps of the piece of veneer to be attached and in this position are connected by glue applied in the joint between the two toothed butt edges, the glue first being on one Application area is applied and at least one of the veneer strips is then pushed over this application area, whereby its front abutting edges are wetted with glue.

Aus der DE-PS 25 23 203 ist ein Stanzwerkzeug zur Herstellung gezahnter Stoßkanten an zu Streifen zu verbindenden Furnierstücken bekannt.From DE-PS 25 23 203 a punching tool for producing toothed butt edges on veneer pieces to be connected to strips is known.

Aus der DE-OS 35 26 372 ist ein Verfahren zum Verleimen gezahnter Stoßkanten von Furnierstreifen bekannt, bei welchem eine Auftrag-Walze mit gekrümmter Oberfläche vorgesehen ist, die mit einem Leimfilm benetzt wird. Auf diese Auftrag-Walze wird einer der zu verleimenden Furnierstücke mit seiner gezahnten Stoßkante geschoben und dadurch Leim von dieser Auftrag-Walze an der gezahnten Stirnseite abgestreift. Sodann wird dieser Furnierstreifen zu einer weiteren Arbeitsstation transportiert, um dort mit dem zweiten Furnierstück zusammengeführt zu werden.From DE-OS 35 26 372 a method for gluing toothed butt edges of veneer strips is known, in which an application roller with a curved surface is provided which is wetted with a glue film. One of the veneer pieces to be glued is pushed onto this applicator roller with its toothed butt edge, thereby removing glue from this applicator roller on the toothed end face. This veneer strip is then transported to another work station in order to be brought together with the second piece of veneer.

Dies ist nicht nur umständlich, sondern schließt auch die Gefahr ein, daß der naturgemäß nur in einer sehr geringen Menge an den Stoßkanten der Zähne des Furnierstreifens aufgebrachte Leim durch die Walzenbeleimung auch die Furnierfläche verschmiert und außerdem die Leimauftrag-Walze allmählich mit auszuhärtendem Leim benetzt oder aber immer wieder gereinigt werden muß.This is not only cumbersome, but also includes the risk that the glue, which is naturally only applied in a very small amount to the abutting edges of the teeth of the veneer strip, will also smear the veneer surface due to the roller gluing and also gradually wet the glue application roller with hardenable glue or but has to be cleaned again and again.

Es besteht deshalb die Aufgabe, ein Verfahren der eingangs erwähnten Art zu schaffen, bei welchem den Furnierstücken genausoviel Leim zugeführt wird, wie jeweils zu ihrer Verbindung erforderlich ist¸ gleichzeitig dabei aber aufwendige Zwischentransporte von mit Leim schon versehener Furnierstücke zu vermeiden. Ferner besteht die Aufgabe, eine Vorrichtung gemäß dem Oberbegriff des Anspruches 6 zu schaffen, die eine möglichst einfache Durchführung des Verfahrens mit möglichst geringem maschinelem Aufwand gestattet.There is therefore the task of creating a method of the type mentioned at the outset in which as much glue is fed to the veneer pieces as is necessary for their connection, but at the same time avoiding expensive intermediate transport of veneer pieces already provided with glue. Furthermore, there is the task of creating a device according to the preamble of claim 6, which allows the method to be carried out as simply as possible with as little machine effort as possible.

Die Lösung dieser Aufgabe ist im Verfahren nach Anspruch 1 definiert.The solution to this problem is defined in the method according to claim 1.

Es wird also nicht eine ganze rotierende Auftrag-Walze mit Leim benetzt und dann der Furnierstreifen in den Bereich dieser Walze gebracht und ein Teil des Leimes von der Walze an der Stirnseite des Furnierstückes abgestreift, sondern die dosierte und benötigte Leimmenge wird streifenförmig oder in mehreren Flecken nebeneinander, also in definierter Breite, auf einer ebenen Auftrag-Fläche aufgetragen, auf welcher dann beide Furnierstücke in leimfreien Zonen angeordnet und von dort zusammengeführt und dabei mit diesem Leim benetzt werden können. Da die Leimmenge je nach Größe der Zähne und Dicke der Furnierstreifen vordosiert ist, kann sie dabei praktisch vollständig an die Furnierstücke gebracht werden, so daß kein Problem einer nachträglich immer wieder zu reinigenden Walze mit überschüssigen Leimmengen besteht. Darüber hinaus entfällt ein Zwischentransport eines mit Leim versehenen Furnierstückes zu einer entfernten Arbeitsstation, weil die beiden Furnierstreifen unmittelbar dort zusammengeführt und -gefügt werden können, wo auch der Leim aufgetragen wurde.It is not a whole rotating applicator roller that is wetted with glue and then the veneer strip is brought into the area of this roller and part of the glue is stripped from the roller on the front side of the veneer piece, but the metered and required amount of glue is strip-shaped or in several spots applied next to each other, i.e. in a defined width, on a flat application surface, on which both pieces of veneer can then be arranged in glue-free zones and brought together from there and wetted with this glue. Since the amount of glue is pre-metered depending on the size of the teeth and thickness of the veneer strips, it can be brought practically completely to the veneer pieces, so that there is no problem of a roll with excess amounts of glue which has to be cleaned again and again afterwards. In addition, there is no intermediate transport of a piece of veneer provided with glue to a remote work station, because the two strips of veneer can be brought together and joined directly where the glue was applied.

Dabei ist es besonders zweckmäßig, wenn beide Furnierstreifen aufeinanderzu geschoben und zu gleichen Teilen durch den Leimstreifen bewegt werden. Dies ergibt eine gleichmäßige Verklebung der gezahnten Stirnseiten.It is particularly useful if both veneer strips are pushed towards each other and moved in equal parts through the glue strip. This results in an even bond of the toothed end faces.

Dabei kann der Leimstreifen od.dgl. so dosiert werden, daß beim Zusammenführen der Furnierstücke und ihrer Zähne jeweils etwa die Hälfte der Flanken der Zähne, von ihrer Spitze ausgehend, mit Leim benetzt werden. Somit können jeweils die mit Leim benetzten Bereiche der Zähne des einen Furnierstückes die nicht mehr mit Leim benetzten Bereiche der Zahnlücken ihrerseits mit Leim versehen bzw. dort zu einer entsprechenden Verklebung führen.The glue strip or the like. be dosed so that when the veneer pieces and their teeth are brought together, about half of the flanks of the teeth, starting from their tips, are wetted with glue. Thus, the areas of the teeth of the one veneer piece wetted with glue can in turn provide the areas of the tooth gaps that are no longer wetted with glue with glue or lead there to corresponding gluing.

Nach dem Zusammenschieben und Zusammenfügen der beiden gezahnten Enden der Furnierstücke kann zumindest der Fügebereich gegen die Auftrag-Fläche gepreßt und dabei vorzugsweise beheizt werden. Besonders zweckmäßig ist es dabei, wenn die Furnierstreifen nach dem Zusammenführen an ihrer der Leimauftrag-Fläche abgewandten Oberseite beheizt werden. Die Beheizung und Pressung beschleunigt den Abbindeprozeß und verbessert die Verleimung. Die gleichzeitige Anpressung verbessert dabei den Wärmeübergang. Durch diese Beschleunigung der Aushärtung des Leimes sind schnellere Taktzeiten möglich.After pushing the two together Toothed ends of the veneer pieces, at least the joining area can be pressed against the application surface and preferably heated. It is particularly expedient if the veneer strips are heated after they have been brought together on their upper side facing away from the glue application surface. The heating and pressing accelerates the setting process and improves the gluing. The simultaneous pressing improves the heat transfer. This acceleration of the curing of the glue enables faster cycle times.

Vorrichtungen zum Verleimen gezahnter Stoßkanten von zu verbindenden Furnierstücken oder -streifen sind in den Ansprüchen 6 und 7 definiert. Eine solche Vorrichtung ist sehr einfach und dennoch effektiv, weil ein Zusammenschieben der beiden Furnierstücke mit großer Sicherheit dazu führt, daß diese an ihren Stoßkanten mit Leim benetzt und mit ihren Zähnen jeweils in die analogen Zahnlücken gebracht werden, ohne einander vor allem auch nach oben ausweichen zu können.Devices for gluing toothed butt edges of veneer pieces or strips to be joined are defined in claims 6 and 7. Such a device is very simple and yet effective because pushing the two pieces of veneer together with great certainty leads to the fact that they are wetted with glue at their abutting edges and brought into the analog tooth gaps with their teeth without, above all, evading one another to be able to.

Dabei kann die Leimauftrag-Vorrichtung als Auftrag-Düse, Auftrag-Rolle oder -Rad od.dgl. ausgebildet sein. Während also ein dosierter Leimstreifen oder eine Reihe dosierter Leimflecken auf der Auftrag-Fläche oder -Platte mit Hilfe einer Auftrag-Düse od.dgl. angebracht werden, ist die obere Begrenzung und Führung zum Niederhalten der aufeinanderzugeschobenen Stoßkanten und Stirnseiten der Furnierstücke nicht im Wege.The glue application device as an application nozzle, application roller or wheel or the like. be trained. So while a metered glue strip or a row of metered glue spots on the application surface or plate with the help of an application nozzle or the like. attached, the upper limit and guide to hold down the pushed edges and end faces of the veneer pieces is not in the way.

Dabei ist es besonders vorteilhaft, wenn dieser Preßbalken beheizt ist. Die Heizleistung und -wärme wird dann besonders gut auf die Klebestelle übertragen, so daß eine schnelle Aushärtung des Leimes und somit kurze Taktzeiten an dieser Vorrichtung möglich sind. Während des Zusammenführens der Furnierstücke hat der Preßbalken vorteilhafterweise von der Leimauftrag-Platte einen vorzugsweise einstellbaren Abstand etwa von der Dicke der zu verleimenden Furnierstreifen. Dadurch wird die gewünschte Führung für die Leimstücke sichergestellt und dennoch deren Zusammenführen nicht behindert. Durch die Einstellbarkeit des Abstandes des Preßbalkens von der Leimauftrag-Fläche ist eine Anpassung an unterschiedlich dicke Furnierstreifen möglich.It is particularly advantageous if this press beam is heated. The heating power and heat are then transferred particularly well to the gluing point, so that a quick curing of the glue and thus short cycle times are possible on this device. When the veneer pieces are brought together, the press beam advantageously has a preferably adjustable distance from the glue application plate, for example approximately from the thickness of the veneer strips to be glued. This ensures the desired guidance for the glue pieces and yet does not hinder their merging. Due to the adjustability of the distance of the press beam from the glue application surface, it is possible to adapt to veneer strips of different thicknesses.

Um eine gute Anlage der Furnierstücke an der Auftrag-Fläche während ihres Zusammenführens sicherzustellen, kann die Leimauftrag-Platte an ihren quer zur Zuführung der beiden Furnierstreifen liegenden Rändern zu ihrer Oberfläche hin ansteigende Schrägflächen od.dgl. Leitflächen für die streifenförmigen Furnierstücke und deren gezahnte Stoßstellen aufweisen. Diese Leitflächen führen zu der eigentlichen Auftrag-Fläche und verhindern beim Zuführen der Furnierstücke, daß diese ggfs. am Rand der Auftrag-Fläche gestaucht werden.In order to ensure a good contact of the veneer pieces on the application surface while they are being brought together, the glue application plate or the like can increase on its surface at the edges lying transversely to the feed of the two veneer strips. Have guiding surfaces for the strip-shaped veneer pieces and their toothed joints. These guiding surfaces lead to the actual application surface and prevent the veneer pieces from being compressed at the edge of the application surface when the veneer pieces are fed in.

Die schon erwähnte Leimauftrag-Vorrichtung ist zweckmäßigerweise über die quer zur Bewegungsrichtung der Furnierstücke angeordnete Mitte der insbesondere aus Metall bestehenden Auftrag-Platte bewegbar und kann vorzugsweise einen Bruchteil der Breite der Auftrag-Fläche insbesondere in deren Mittelabschnitt beaufschlagen. Dadurch erhalten beide Furnierstücke oder -streifen seitlich der beleimten Zone der Auftrag-Fläche etwa den gleichen Schiebeweg bei ihrem Zusammenfügen und können dann von dem einzigen Leimstreifen jeweils etwa die Hälfte des Leimes mit ihren Stoßkanten aufnehmen.The glue application device already mentioned is expediently arranged transversely to the direction of movement of the Veneer pieces arranged center of the application plate, which is made in particular of metal, can be moved and can preferably act on a fraction of the width of the application surface, in particular in its central section. As a result, both veneer pieces or strips on the side of the glued zone of the application surface receive approximately the same sliding path when they are joined together and can then take up about half of the glue with their abutting edges from the single glue strip.

Die Vorrichtung nach Anspruch 7 unterscheidet sich von der nach Anspruch 6 im wesentlichen dadurch, daß die Auftrag-Platte relativ zu der - entsprechend bemessenen - Leimauftragvorrichtung quer zur Bewegungsrichtung der Furnierstücke bewegbar ist, um dabei mit Leim in einer definierten Breite oder Streifenzone benetzt zu werden.The device according to claim 7 differs from that according to claim 6 essentially in that the application plate is movable relative to the - appropriately dimensioned - glue application device transversely to the direction of movement of the veneer pieces, in order to be wetted with glue in a defined width or strip zone .

Die in Bewegungsrichtung der Furnierstücke bei deren Zusammenschieben verlaufende Breite der Führung oder des Preßbalkens kann vorzugsweise wenigstens etwa einem Viertel der Länge der an den Furnierstücken vorgesehenen und ineinanderschiebbaren Zähne entsprechen und die den Furnierstücken zugewandte Führungsfläche dieser Führung bzw. des Preßbalkens kann parallel zur Auftragfläche sein. Dies genügt für eine gute Führung und Verpressung der Zähne nach dem Zusammenschieben der Furnierstreifen.The width of the guide or of the press beam, which extends in the direction of movement of the veneer pieces when they are pushed together, can preferably correspond to at least about a quarter of the length of the teeth provided on the veneer pieces and can be pushed into one another, and the guide surface of the guide or of the press beam facing the veneer pieces can be parallel to the application area. This is sufficient for good guiding and pressing of the teeth after the veneer strips have been pushed together.

Eine noch bessere Führung ergibt sich, wenn die Breite der Führung bzw. des Preßbalkens etwa ein Drittel bis die Hälfte der Länge der Zähne der Furnierstücke oder bis etwa der gesamten Länge dieser Zähne entspricht.An even better guidance results if the width of the guidance or of the pressure beam corresponds to approximately one third to half the length of the teeth of the veneer pieces or to approximately the entire length of these teeth.

Nachstehend ist die Erfindung mit ihren ihr als wesentlich zugehörenden Einzelheiten anhand der Zeichnung in einem Ausführungsbeispiel noch näher beschrieben.The invention is described in more detail below with its details that are essential to it, using the drawing in an exemplary embodiment.

Es zeigt in schematisierter Darstellung:

Fig. 4
a plan view of two pieces of veneer - omitting the guide located above - after the teeth in large part in the tooth gaps of the other Veneer piece penetrated and about half are wetted with glue at their joints.

Zum Verleimen gezahnter Stoßkanten 1 von zu verbindenden Furnierstücken 2 und 3 ist vorgesehen, daß jeweils die Zähne 4 des einen Furnierstückes 2 in Zahnlücken 5 des anzufügenden Furnierstückes 3 und umgekehrt eingeschoben und in dieser Postion durch in der Fuge zwischen den beiden gezahnten Stoßkanten 1 aufgetragenen Leim verbunden werden.For gluing toothed abutting edges 1 of veneer pieces 2 and 3 to be connected, it is provided that the teeth 4 of one veneer piece 2 are inserted into tooth gaps 5 of the veneer piece 3 to be attached and vice versa and in this position by glue applied in the joint between the two toothed abutting edges 1 get connected.

Dabei wird der Leim zunächst gemäß Fig. 1 als Leimstreifen 6 auf einer Auftrag-Fläche 7 aufgetragen und dann wenigstens eines der Furnierstücke 2 oder 3 über diese Auftrag-Fläche 7 geschoben, wie es durch die Pfeile Pf 1 in Fig. 1 und die gegenüber der Fig. 1 geänderte Anordnung der Furnierstücke 2 und 3 in Fig. 2 angedeutet ist. Dabei zeigen die Figuren 2 und vor allem 4, daß dadurch die stirnseitigen Stoßkanten der Zähne 4 zumindest bereichsweise mit dem Leim benetzt werden.1 is first applied as a glue strip 6 on an application surface 7 and then at least one of the veneer pieces 2 or 3 is pushed over this application surface 7, as indicated by the arrows Pf 1 in FIG. 1 and opposite 1 modified arrangement of the veneer pieces 2 and 3 in Fig. 2 is indicated. Figures 2 and especially 4 show that the front abutting edges of the teeth 4 are at least partially wetted with the glue.

Im einzelnen wird dabei so verfahren, daß die beiden Furnierstücke 2 und 3 mit einer Flachseite, im Ausführungsbeispiel ihrer Unterseite, und gegeneinanderweisenden Zähnen 4 auf der Auftrag-Fläche 7 zunächst mit Abstand zueinander angeordnet werden, wie es beispielsweise auch Fig. 3 zeigt, während Fig. 1 sogar noch einen noch größeren Abstand dieser Furnierstücke 2 und 3 vor ihrem Erreichen der Auftrag-Fläche 7 darstellt.In detail, the procedure is such that the two veneer pieces 2 and 3 with a flat side, in the exemplary embodiment of their underside, and opposing teeth 4 on the application surface 7 are initially arranged at a distance from one another, as is also shown, for example, in FIG. 3, during Fig. 1 represents an even greater distance between these veneer pieces 2 and 3 before they reach the application surface 7.

In dem Zwischenraum zwischen den beiden einander zugewandten Stirnseiten der zu verbindenden Furnierstücke 2 und 3 wird zuvor, gleichzeitig oder nach der entsprechenden Anordnung der Furnierstücke 2 und 3 gemäß Fig. 1 der dosierte Leimstreifen 6 - ggfs. auch eine Reihe von Leimflecken oder -punkten - aufgetragen, wobei dieser Vorgang in Fig. 1 gerade in Gang ist und eine entsprechende Leimauftrag-Vorrichtung 8 quer zur Längserstreckung der Furnierstücke 2 und 3 über die Auftrag-Fläche 7 bewegt wird, wobei ihre Dosiervorrichtung 9 den Leimstreifen 6 abgibt und auf der Auftrag-Fläche 7 anordnet.In the space between the two facing end faces of the veneer pieces 2 and 3 to be connected is previously, simultaneously or after Corresponding arrangement of the veneer pieces 2 and 3 according to FIG. 1, the metered glue strip 6 — possibly also a series of glue spots or spots — is applied, this process being in progress in FIG. 1 and a corresponding glue application device 8 transversely to the longitudinal extent the veneer pieces 2 and 3 are moved over the application surface 7, their metering device 9 dispensing the glue strip 6 and arranging it on the application surface 7.

Danach werden die beiden Furnierstücke 2 und 3 jeweils aufeinanderzubewegt und dabei mit ihren Zähnen 4 gemäß Fig. 4 durch den Leimstreifen 6 hindurchgeschoben. Gemäß Fig. 2 und 3 werden dabei die Furnierstücke 2 und 3 auf ihrer der den Leim aufweisenden Auftragfläche 7 abgewandten Oberseite 10 geführt und niedergehalten. Vor allem die Figuren 2 und 4 verdeutlichen, daß die beiden Furnierstücke 2 und 3 aufeinanderzu geschoben und zu gleichen Teilen durch den Leimstreifen 6 bewegt werden. Dabei wird dieser Leimstreifen 6 von der Dosiervorrichtung oder Ausgabevorrichtung 9 der Leimauftrag-Vorrichtung 8 so dosiert, daß beim Zusammenführen der Furnierstücke 2 und 3 und ihrer Zähne 4 jeweils etwa die Hälfte der Flanken der Zähne 4, von ihrer Spitze 4a ausgehend, mit Leim benetzt werden, wie es in Fig. 4 angedeutet ist. Nach dem Zusammenschieben und Zusammenfügen der beiden gezahnten Enden 1 der Furnierstücke 2 und 3 wird zumindest dieser Fügebereich gegen die Auftrag-Fläche 7 gepreßt und dabei vorzugsweise beheizt. Dabei geschieht diese Beheizung im Ausführungsbeispiel an der der Leimauftrag-Fläche 7 abgewandten Oberseite 10 der Furnierstücke 2 und 3, d.h. die die Leimauftrag-Fläche 7 aufweisende Auftrag-Platte 11 ist unbeheizt, um nicht ein vorzeitiges Aushärten des Leimstreifens 6 zu verursachen.Then the two pieces of veneer 2 and 3 are moved towards each other and their teeth 4 are pushed through the glue strip 6 according to FIG. 4. 2 and 3, the veneer pieces 2 and 3 are guided and held down on their upper side 10 facing away from the application surface 7 containing the glue. Figures 2 and 4 in particular illustrate that the two veneer pieces 2 and 3 are pushed towards one another and moved in equal parts by the glue strip 6. This glue strip 6 is dosed by the metering device or dispenser 9 of the glue application device 8 such that when the veneer pieces 2 and 3 and their teeth 4 are brought together, about half of the flanks of the teeth 4, starting from their tip 4a, are wetted with glue are, as indicated in Fig. 4. After the two toothed ends 1 of the veneer pieces 2 and 3 have been pushed together and joined, at least this joining area is pressed against the application surface 7 and is preferably heated in the process. This heating takes place in the exemplary embodiment on the top 10 of the veneer pieces 2 and 3 facing away from the glue application surface 7, ie the application plate 11 having the glue application surface 7 is unheated so as not to cause the glue strip 6 to harden prematurely.

Die den Leim aufnehmende Auftragfläche 7 ist dabei eben und oberhalb dieser ebenen Auftragfläche 7 erkennt man als obere Begrenzung des Schiebeweges der Furnierstücke 2 und 3 die schon erwähnte Führung, die im Ausführungsbeispiel als Preßbalken 12 ausgebildet und nach dem Zusammenstoß der Furnierstreifen abwärts bewegbar und anpreßbar ist. Die außerdem zu der Vorrichtung zum Verleimen gezahnter Stoßkanten 1 von zu verbindenden Furnierstücken 2 und 3 gehörende Leimauftrag-Vorrichtung 8 zum Benetzen eines Bereiches der ebenen Auftrag-Fläche 7 mit Leim wurde bereits erwähnt. Die obere Begrenzung und Führung, also der Preßbalken 12, ist aus dem Bereich der Leimauftrag-Platte 11 wegbewegbar, so daß die Leimauftrag-Vorrichtung 8 in den Bereich der Auftrag-Fläche 7 bewegbar und über diese hinwegführbar ist. Sie kann dabei als Auftrag-Düse, Auftrag-Rolle oder -Rad od.dgl. ausgebildet sein.The glue-receiving application surface 7 is flat and above this flat application surface 7 can be seen as the upper limit of the sliding path of the veneer pieces 2 and 3, the aforementioned guide, which in the exemplary embodiment is designed as a press beam 12 and after the collision of the veneer strips can be moved downwards and can be pressed on . The glue application device 8, which also belongs to the device for gluing toothed abutting edges 1 of veneer pieces 2 and 3 to be connected, for wetting a region of the flat application surface 7 with glue has already been mentioned. The upper limit and guide, that is to say the press beam 12, can be moved away from the area of the glue application plate 11, so that the glue application device 8 can be moved into the area of the application surface 7 and can be guided over it. It can be used as an application nozzle, application roller or wheel or the like. be trained.

In Fig. 3 ist angedeutet, daß der Preßbalken 12 Heizungen 13 enthält, mit denen er und somit auch der Fügebereich der Furnierstücke 2 und 3 beheizt werden können, um nach dem Zusammenfügen die Aushärtzeit des Leimes zu vermindern und so die Taktzeit des Verfahrens und auch der Vorrichtung zu erhöhen. Während des Zusammenführens der Furnierstücke 2 und 3 hat der Preßbalken 12 gemäß Fig. 3 von der Leimauftrag-Platte 11 einen vorzugsweise auf die Dicke der zu verleimenden Furnierstreifen oder Furnierstücke 2 und 3 einstellbaren Abstand, durch welchen das Zusammenführen nicht behindert, aber ein gegenseitiges Überklettern und Überschieben der beiden Furnierstücke 2 und 3 ausgeschlossen wird. Durch die Einstellbarkeit dieses Abstandes können unterschiedlich dicke Furnierstreifen berücksichtigt werden. Dabei zeigt Fig. 3 gleichzeitig, daß die Dicke des Leimstreifens 6 ebenfalls etwa der Dicke der Furnierstreifen entsprechend gewählt wurde.In Fig. 3 it is indicated that the press beam 12 contains heaters 13, with which he and thus the joining area of the veneer pieces 2 and 3 can be heated in order to reduce the curing time of the glue after assembly and so the cycle time of the method and also to increase the device. During the merging of the veneer pieces 2 and 3, the pressure beam 12 according to FIG. 3 has a distance from the glue application plate 11 which is preferably adjustable to the thickness of the veneer strips or veneer pieces 2 and 3 to be glued, by means of which the merging does not hinder, but does climb over each other and sliding the two veneer pieces 2 and 3 is excluded. Due to the adjustability of this distance, veneer strips of different thicknesses can be taken into account. 3 shows at the same time that the thickness of the glue strip 6 is also approximately the thickness of the veneer strips was chosen accordingly.

In den Figuren 1 bis 3 erkennt man außerdem, daß die Leimauftrag-Platte 11 an ihren quer zur Zuführung der beiden Furnierstücke 2 und 3 leigenden Rändern zu ihrer Oberfläche, der Auftrag-Fläche 7, hin ansteigende Schrägflächen oder Leit -Flächen 14 für die streifenförmigen Furnierstücke 2 und 3 und deren gezahnte Stoßkanten 1 aufweist, um eine gute Zuführung aus der Lage gemäß Fig. 1 zu erreichen.In Figures 1 to 3 you can also see that the glue application plate 11 at their edges transverse to the feed of the two veneer pieces 2 and 3 to their surface, the application surface 7, increasing inclined surfaces or guide surfaces 14 for the strip-shaped Veneer pieces 2 and 3 and their toothed abutting edges 1 in order to achieve a good supply from the position shown in FIG. 1.

Es sei noch erwähnt, daß die Leimauftrag-Vorrichtung 8 im Ausführungsbeispiel über die quer zur Bewegungsrichtung der Furnierstücke 2 und 3 angeordnete Mitte der insbesondere aus Metall bestehenden Auftrag-Platte 11 bewegbar ist und dabei in deren Mittelabschnitt einen Bruchteil der Breite B der Auftrag-Fläche 7 beaufschlagt, so daß für beide Furnierstücke 2 u. 3 jeweils etwa der gleiche Schiebeweg zur Verfügung steht und zurückzulegen ist und gemäß Fig. 4 beide Furnierstreifen jeweils an den vorderen Hälften ihrer Zähne 4 mit etwa einer gleichen Menge von Leim benetzt werden. In Fig. 4 sind dabei die beiden streifenförmigen Furnierstücke 2 und 3 nur teilweise dargestellt und teilweise weggebrochen, wobei im weggebrochenen Bereich noch einmal der Leimstreifen 6 in seiner ursprünglichen Form zu sehen ist, woraus deutlich wird, wie dieser Leimstreifen durch die von beiden Seiten in ihn eindringenden Zähne 4 der Furnierstücke 2 und 3 auf deren Flanken verteilt wird.It should also be mentioned that the glue application device 8 in the exemplary embodiment can be moved over the center of the application plate 11, which is made in particular of metal, arranged transversely to the direction of movement of the veneer pieces 2 and 3, and in the middle section thereof a fraction of the width B of the application surface 7 applied so that 2 u for both pieces of veneer. 3 approximately the same sliding path is available and has to be covered and, according to FIG. 4, both veneer strips are each wetted on the front halves of their teeth 4 with approximately the same amount of glue. In Fig. 4, the two strip-shaped veneer pieces 2 and 3 are only partially shown and partially broken away, whereby the glue strip 6 can be seen again in its original form in the broken-off area, from which it becomes clear how this glue strip through the from both sides in it penetrating teeth 4 of the veneer pieces 2 and 3 is distributed on the flanks.

Eine andere oder ggfs. auch kombiniert anwendbare Möglichkeit besteht darin, daß die Auftrag-Platte 11 relativ zu der Leimauftragvorrichtung 8 quer zur Bewegungsrichtung der Furnierstücke 2 u. 3 bewegbar ist, um den dosierten Leimstreifen auf dieser Auftragplatte 11 anzubringen. Im manchen Fällen kann es konstruktiv einfacher sein, die Leimauftragvorrichtung 8 außerhalb der Arbeitsstation, wo die beiden Furnierstücke 2 und 3 zusammengeführt werden, stationär vorzusehen und einfach zum Auftragen des Leimes dann die Platte 11 zu dieser Leimauftragvorrichtung 8 und unter dieser hindurch zu bewegen.Another or, if applicable, also combined possibility is that the application plate 11 relative to the glue application device 8 transversely to the direction of movement of the veneer pieces 2 u. 3 is movable to apply the metered glue strip on this application plate 11. In some cases it can be constructive be easier to provide the glue application device 8 stationary outside the work station, where the two veneer pieces 2 and 3 are brought together, and then simply to move the plate 11 to the glue application device 8 and under it to apply the glue.

Die in Bewegungsrichtung der Furnierstücke oder -streifen 2 u. 3 bei deren Zusammenschieben verlaufende Breite der Führung bzw. des Preßbalkens 12 entspricht wenigstens etwa einem Viertel, ggfs. auch einem Drittel bis der Hälfte der Länge der an den Furnierstücken vorgesehenen und ineinanderschiebbaren Zähnen 4, wobei die den Furnierstücken zugewandte Führungsfläche dieser Führung bzw. des Preßbalkens 12 parallel zur Auftragfläche 7, also ebenfalls eben ist. In Fig. 2 erkennt man, daß diese Breite des Preßbalkens 12 sogar etwa der gesamten Länge dieser Zähne 4 entspricht oder sie noch etwas übertrifft, so daß zumindest in zusammengeschobener Position eine gute Verpressung möglich ist.The in the direction of movement of the veneer pieces or strips 2 u. 3 when the width of the guide or of the press beam 12 is pushed together corresponds to at least about a quarter, possibly also a third to half of the length of the teeth 4 which are provided and can be pushed into one another on the veneer pieces, the guide surface of the guide facing the veneer pieces of this guide or Press bar 12 parallel to the application surface 7, so it is also flat. In Fig. 2 it can be seen that this width of the press beam 12 even corresponds approximately to the entire length of these teeth 4 or slightly exceeds them, so that good compression is possible at least in the pushed-together position.
