Abstract

The adhesive is held in an air- and watertight casing (5) in the groove (3). During adhesion, the tongue (9) is inserted in the groove, breaking the casing and releasing adhesive. Preferred features: The casing is an extruded flexible tube inserted into the groove, being filled in a second stage. It is alternatively filled during manufacture. The method is applicable in a general sense, to projection and recess jointing of objects.

Description

Die Verbindung betrifft ein Verfahren zum Verkleben eines ersten Gegen­ standes, der einen Hohlraum aufweist, mit einem zweiten Gegenstand, der einen in etwa komplementär zu dem Hohlraum des ersten Gegenstandes ausgebildeten Vorsprung aufweist.The connection relates to a method for gluing a first counter stood, which has a cavity, with a second object, the one approximately complementary to the cavity of the first object trained projection.

Solche Gegenstände sind insbesondere, aber nicht ausschließlich, als Nut- und Feder-Elemente bekannt. Das Verkleben solcher Gegenstände bereitet erhebliche praktische Schwierigkeiten. Nach dem Stand der Technik ist es erforderlich, daß beim Verkleben solcher Gegenstände vor Ort der Klebstoff aufgebracht wird. Dafür ist das Mitführen und das Aufbringen von Klebstoff erforderlich, was zeitaufwendig ist und leicht zu einem Verschmutzen der miteinander zu verklebenden Gegenstände führt. Außerdem ist nicht immer der geeignete Klebstoff vorhanden oder er wird nicht richtig dosiert.Such items are particularly, but not exclusively, as Tongue and groove elements known. Preparing to glue such objects considerable practical difficulties. According to the state of the art it is required that when gluing such objects on site the adhesive is applied. This is carried along and the application of glue required, which is time consuming and easy to contaminate the leads to objects to be glued together. Besides, it is not always the appropriate adhesive is available or it is not dosed correctly.

Der Erfindung lag daher die Aufgabe zugrunde, ein Verfahren zum Ver­ kleben von Gegenständen bereitzustellen, bei dem der erste Gegenstand einen Hohlraum und der zweite Gegenstand einen in etwa komplementär zu dem Hohlraum ausgebildeten Vorsprung aufweist, das sauber und zeitsparend unter Verwendung des geeigneten Klebstoffs erfolgt.The invention was therefore based on the object of a method for ver provide sticking of objects in which the first object is a Cavity and the second object is approximately complementary to that Has cavity-shaped projection that is clean and time-saving using the appropriate adhesive.

Gelöst wird diese Aufgabe durch ein Verfahren, bei dem der Klebstoff in einer luft- und feuchtigkeitsdichten Umhüllung in den Hohlraum des ersten Gegenstandes eingebracht wird, wobei der Vorsprung des zweiten Gegen­ standes beim Verkleben durch Eingreifen in den Hohlraum die Umhüllung zerstört und den Klebstoff freisetzt.This problem is solved by a process in which the adhesive is in an airtight and moistureproof envelope in the cavity of the first Object is introduced, the projection of the second counter  stood by the encapsulation by engaging in the cavity destroyed and the adhesive released.

Erfindungsgemäße Gegenstände sind insbesondere Nut- und Feder-Elemente. Die Erfindung ist aber nicht auf solche Elemente beschränkt. Es ist bei­ spielsweise genauso denkbar, daß ein Bolzen in einen entsprechend komp­ lementär ausgebildeten Hohlraum eingreift und dort nach dem erfindungs­ gemäßen Verfahren verklebt wird. Daneben sind vielfältige weitere Ausge­ staltungen des Hohlraumes des ersten Gegenstandes und des in etwa kom­ plementär zu diesem Hohlraum ausgebildeten Vorsprunges des zweiten Gegenstandes möglich und von dem erfindungsgemaßen Verfahren erfaßt.Objects according to the invention are in particular tongue and groove elements. However, the invention is not restricted to such elements. It is at for example, just as conceivable that a bolt in a comp elementarily trained cavity engages and there according to the Invention is glued according to the procedure. In addition, there are many other options events of the cavity of the first object and the approximately com complementary to this cavity formed projection of the second Subject possible and covered by the inventive method.

Das erfindungsgemäße Verfahren bietet den Vorteil, daß bereits der Herstel­ ler der zu verklebenden Gegenstände den Klebstoff zufügen kann und somit immer gewährleistet ist, daß ein geeigneter Klebstoff verwendet wird. Außerdem ist gewährleistet, daß die Klebstoffmenge exakt dosiert wird, was die Qualität der Verklebung, insbesondere ihre Dauerhaftigkeit, günstig beeinflußt. Es kann kein unplanmäßiges Austreten des Klebers erfolgen, wodurch ein Verschmutzen der zu verklebenden Gegenstände wirksam verhindert wird, und das Verkleben kann immer sauber und zeitsparend erfolgen.The method according to the invention has the advantage that the manufacturer ler of the objects to be glued can add glue and thus it is always ensured that a suitable adhesive is used. It also ensures that the amount of adhesive is dosed exactly what the quality of the bond, especially its durability, is favorable influenced. There can be no unscheduled leakage of the adhesive, thereby effectively soiling the objects to be glued is prevented, and sticking can always be clean and time-saving respectively.

Gemäß einer vorteilhaften Ausführungsform des erfindungsgemäßen Ver­ fahrens wird die Umhüllung, die den Klebstoff beeinhaltet, in Form eines extrudierten Schlauches ausgebildet. Es wird jedoch darauf hingewiesen, daß die Art und Form der Umhüllung an die Ausbildung des Hohlraumes und des Vorsprunges angepaßt sein sollte. Die Umhüllung ist daher nicht auf einen Schlauch beschränkt, sondern kann vielfältige Formen aufweisen und in unterschiedlicher Weise hergestellt sein. According to an advantageous embodiment of the Ver driving, the wrapping, which contains the adhesive, is in the form of a extruded hose. However, it should be noted that the type and shape of the envelope to the formation of the cavity and the projection should be adjusted. The wrapper is therefore not open limited a hose, but can have a variety of shapes and be made in different ways.  

Die Umhüllung kann in einem ersten Schritt in den Hohlraum eingebracht und in einem zweiten Schritt mit dem Klebstoff befüllt werden. Es ist aber genauso möglich, den Schlauch bereits bei seiner Extrusion mit dem Kleb­ stoff zu befüllen. Entsprechend kann eine nicht in Schlauchform ausgebildete Umhüllung bereits bei ihrer Herstellung mit dem Klebstoff befüllt werden.The casing can be introduced into the cavity in a first step and be filled with the adhesive in a second step. But it is just as possible, the hose already during its extrusion with the adhesive fill fabric. Accordingly, a non-tubular one can be used Envelope to be filled with the adhesive during their manufacture.

Im folgenden soll die Erfindung anhand eines in der beigefügten Zeichnung dargestellten Ausführungsbeispieles näher erläutert werden. Es zeigen:In the following the invention with reference to one in the attached drawing illustrated embodiment are explained in more detail. Show it:

Fig. 1 eine schematische Darstellung eines Nut- und Feder-Elementes vor der Verklebung, Fig. 1 is a schematic representation of a tongue and groove element prior to bonding,

Fig. 2 eine schematische Abbildung eines Nut- und Feder-Elementes nach seiner Verklebung und Fig. 2 is a schematic illustration of a tongue and groove element after its bonding and

Fig. 3 eine unvollständige schematische Darstellung des Befüllens eines Schlauches während seiner Herstellung. Fig. 3 is an incomplete schematic representation of the filling of a hose during its manufacture.

In Fig. 1 ist ein erster Gegenstand 1 dargestellt, der an seinem einen Ende mit einem eine Öffnung aufweisenden Hohlraum 3 ausgebildet ist. In diesen Hohlraum 3 wurde eine Umhüllung 5 in Form eines Schlauches eingebracht, die mit einem Klebstoff auf Polyurethanbasis gefüllt ist.In Fig. 1, a first object 1 is shown, which is formed at one end with a cavity 3 having an opening. In this cavity 3 , an envelope 5 was introduced in the form of a tube, which is filled with an adhesive based on polyurethane.

Mit diesem ersten Gegenstand 1 soll ein zweiter Gegenstand 7 verklebt werden. Der zweite Gegenstand 7 weist an einem Ende einen Vorsprung 9 auf, der in etwa komplementär zu dem Hohlraum 3 des ersten Gegenstands 1 ausgebildet ist. Um den ersten mit dem zweiten Gegenstand zu verkleben, wird der Vorsprung 9 mit dem Hohlraum 3 in Eingriff gebracht, wie Fig. 2 dies zeigt. A second object 7 is to be glued to this first object 1 . The second object 7 has a projection 9 at one end, which is approximately complementary to the cavity 3 of the first object 1 . In order to glue the first to the second object, the projection 9 is brought into engagement with the cavity 3 , as shown in FIG. 2.

Während der Vorsprung 9 des zweiten Gegenstandes 7 in den Hohlraum 3 des ersten Gegenstandes 4 eingreift, wird die den Klebstoff aufweisende Umhüllung 5 in Form des Schlauches zerdrückt und der Klebstoff dadurch freigesetzt. Der Klebstoff ist entweder luft-, feuchtigkeitshärtend oder härtet durch Trocknen und bewirkt durch das Freisetzen eine innige Verbindung zwischen dem ersten und dem zweiten Gegenstand 1, 7. Geeignete Kleber sind beispielsweise Lösungen von Polymeren, Dispersionen von Polymeren, Reaktivsysteme wie Polyurethane und Acrylate, Kondensationsprodukte aus Harnstoffen und Aldehyden sowie Leime auf pflanzlicher oder tierischer Basis. Bei dem vorliegenden Ausführungsbeispiel wird durch den ersten und zweiten Gegenstand 1 , 7 ein Nut- und Feder-Element gebildet.While the projection 9 of the second object 7 engages in the cavity 3 of the first object 4 , the sheath 5 containing the adhesive is crushed in the form of the tube and the adhesive is thereby released. The adhesive is either air-curing, moisture-curing or hardens by drying and, through the release, brings about an intimate connection between the first and second objects 1 , 7 . Suitable adhesives are, for example, solutions of polymers, dispersions of polymers, reactive systems such as polyurethanes and acrylates, condensation products made from ureas and aldehydes, and glues based on plants or animals. In the present exemplary embodiment, a tongue and groove element is formed by the first and second objects 1 , 7 .

Die Größe der Umhüllung 5 richtet sich nach der zu dosierenden Klebstoff­ menge und nach der Geometrie des Hohlraumes 3 des ersten Gegenstandes 1, d. h. im vorliegenden Ausführungsbeispiel nach der Größe der Nut. Anstelle des Schlauches kann auch eine andere beliebige Form einer Umhül­ lung 3 gewählt werden.The size of the covering 5 depends on the amount of adhesive to be metered and on the geometry of the cavity 3 of the first object 1 , ie in the present exemplary embodiment on the size of the groove. Instead of the hose, any other form of a wrapping 3 can be chosen.

Für das erfindungsgemäße Verfahren kann eine Umhüllung 5 gewählt wer­ den, die erst in einem zweiten Verfahrensschritt, d. h. nach ihrer Herstel­ lung, mit dem Klebstoff befüllt worden ist. Die Umhüllung 5 kann aber auch gleich bei ihrer Herstellung mit dem Klebstoff befüllt werden. Für den Fall, daß die Umhüllung 5 einen durch Extrusion hergestellten Schlauch dar­ stellt, zeigt Fig. 3 eine Anordnung, die ein Befüllen der Umhüllung 5 wäh­ rend ihrer Herstellung ermöglicht. Dabei ist in Fig. 3 die Düse 11 eines Extruders unvollständig dargestellt, in der sich die Schmelze 13 des die Umhüllung 5 bildenden Kunststoffmaterials befindet. Während des Extrudie­ rens der Umhüllung 5 wird der Klebstoff über eine Zufuhr 15 in die Umhüllung eingebracht. For the method according to the invention, a sheath 5 can be chosen who has been filled with the adhesive only in a second process step, ie after its manufacture. The envelope 5 can also be filled with the adhesive during its manufacture. In the event that the sheath 5 represents a hose produced by extrusion, Fig. 3 shows an arrangement which enables filling of the sheath 5 during production. The nozzle 11 of an extruder, in which the melt 13 of the plastic material forming the sheath 5 is located, is incompletely shown in FIG. 3. During the extrusion of the covering 5 , the adhesive is introduced into the covering via a feed 15 .

Der erste und der zweite Gegenstand 1, 7 können aus beliebigen mitein­ ander verklebbaren Materialien, wie Kunststoff oder Holz, bestehen.The first and the second object 1 , 7 can consist of any other materials that can be glued together, such as plastic or wood.
