Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Isolierglasscheiben aus wenigstens zwei unter Zwischen­lage eines im Randbereich umlaufenden Abstandhalters mitein­ander verbundenen Einzelscheiben, nach dem ein den Abstand­halter bildender Hohlprofilrahmen zuerst auf eine der Ein­zelscheiben aufgeklebt und dann durch Aufkleben der anderen Einzelscheibe abgedeckt wird.The invention relates to a method for producing insulating glass panes from at least two individual panes connected to one another with the interposition of a circumferential spacer, according to which a hollow profile frame forming the spacer is first glued to one of the individual panes and then covered by gluing on the other individual pane.

Bei den bekannten Herstellungsverfahren, die eine Verwendung stabiler Abstandhalterprofile ermöglichen, werden die Ab­standhalter vor dem Einkleben zwischen die Einzelscheiben fertig vorbereitet, wozu die Abstandhalterprofile, meist im Querschnitt rechteckige hohle Aluminium- oder verzinkte Stahlprofile durch stückweises Zusammensetzen einzelner Profilteile oder auch durch geeignetes Biegen eines ent­sprechend langen Profilteiles zu einem geschlossenen Rahmen geformt und mit Adsorptionsmitteln zur Entfeuchtung des Isolierglasscheiben-Innenraums durch entsprechende Perforation der Profilinnenwände gefüllt werden. Nach einem Beschichten der den Scheiben zugewandten Profilflächen mit Dichtungs- und Klebemasse, vorzugsweise Butyl, wird dann der vorgefertigte Abstandhalterrahmen auf eine Ein­zelscheibe aufgesetzt und durch Aufdrücken der zweiten mit der ersten deckungsgleich aufgelegten Einzelscheibe werden dann die Einzelscheiben und der Abstandhalterrahmen miteinander zur Isolierglasscheibe verklebt. Da die Rahmen sehr genau an die jeweiligen Scheibenformate angepaßt sein müssen, verlangt die Vorfertigung der Rahmen das Einhalten engster Toleranzen, wozu beim Aufsetzen der Rahmen auf die Scheiben ein exaktes Ausrichten und Zentrieren kommt, so daß diese bekannten Herstellungsverfahren äußerst um­ständlich und aufwendig sind und sich darüber hinaus auch kaum automatisieren lassen.In the known manufacturing processes, which allow the use of stable spacer profiles, the spacers are prepared prior to being glued between the individual panes, for which purpose the spacer profiles, mostly hollow aluminum or galvanized steel profiles with a rectangular cross section, are assembled by piece-by-piece assembly of individual profile parts or by suitable bending of one long profile part formed into a closed frame and filled with adsorbents for dehumidifying the interior of the insulating glass pane by appropriate perforation of the profile inner walls. After coating the profile surfaces facing the panes with sealant and adhesive, preferably butyl, the prefabricated spacer frame is then placed on a single pane and by pressing on the second single pane, which is congruent with the first the individual panes and the spacer frame are then glued together to form the insulating glass pane. Since the frames have to be adapted very precisely to the respective pane formats, the prefabrication of the frames requires the tightest tolerances to be met, which is precisely aligned and centered when the frames are placed on the panes, so that these known production processes are extremely cumbersome and complex and are can also hardly be automated.

Zum rationelleren Herstellen von Isolierglasscheiben wurde auch schon vorgeschlagen, Abstandhalter in Form flexibler Bänder zu verwenden, die dann direkt zwischen die beiden in aufeinander abgestimmter Lage gehaltenen Einzelscheiben rundumverlaufend eingelegt und dabei dem Scheibenrand ent­sprechend gebogen werden, wodurch der Abstandhalter erst während des Einlegens zwischen die Scheiben entsteht. Aller­dings sind die flexiblen Abstandhalterbänder vor allem hinsichtlich des optischen Eindruckes nicht mit Abstandhal­terprofilen vergleichbar und das Einfügen des Abstandhalter­bandes zwischen zwei Scheiben bringt die Gefahr eines Weg­scherens der für die Verklebung erforderlichen, vor dem Einlegen auf die Scheiben aufgebrachten Klebeschicht und damit die Gefahr einer Verschmutzung und eines Unterwan­derns der Klebeschicht durch Wasser mit sich. Abgesehen davon, müssen bei Vorrichtungen, die ein automatisches Einlegen des Abstandhalterbandes zwischen die Einzelscheiben erlauben, alle die zum Einlegen erforderlichen Einrichtun­gen, wie Klebemitteldüsen, Bandführungsrollen, Scheibenan­drückwalzen, Scheibenhalte- und -schwenkarme u. dgl., räumlich eng beeinander in einem gemeinsamen Arbeitsbereich untergebracht werden, was funktions- und konstruktionstech­nisch beträchtliche Schwierigkeiten bereitet.For the more efficient production of insulating glass panes, it has also already been proposed to use spacers in the form of flexible strips, which are then inserted directly between the two individual panes held in a coordinated position and are bent around the edge of the pane, so that the spacer is only inserted between the panes during insertion arises. However, the flexible spacer tapes are not comparable to spacer profiles, especially with regard to their optical impression, and the insertion of the spacer tape between two panes entails the risk of the adhesive layer required for the adhesive application being sheared away before being placed on the panes, and thus the risk of contamination and one Infiltrating the adhesive layer with water. Apart from this, in devices which allow the spacer tape to be automatically inserted between the individual disks, all the equipment required for insertion, such as adhesive nozzles, tape guide rollers, disk pressure rollers, disk holding and pivoting arms and the like, must be provided. Like., spatially close to each other in a common work area, which is functionally and constructionally considerable difficulties.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und ein Verfahren der eingangs geschilderten Art anzugeben, das die rationelle Herstellung von Isolier­glasscheiben gewährleistet und trotz der Verwendung stabiler Abstandhalterprofile eine verhältnismäßig aufwandsarme, funktionssichere Automatisierung der Isolierglascheiben­fertigung erlaubt.The invention is therefore based on the object of eliminating these deficiencies and of specifying a method of the type described at the outset which ensures the rational production of insulating glass panes and which, despite the use of stable spacer profiles, permits relatively inexpensive, reliable automation of the production of insulating glass panes.

Die Erfindung löst diese Aufgabe dadurch, daß der als durch­gehender Profilstrang vorbereitete Hohlprofilrahmen den Scheibenkanten entsprechend abschnittsweise aufgeklebt wird, indem der Profilstrang nach dem Aufkleben jeweils eines Abschnittes zum Aufkleben des folgenden Abschnittes unter gleichzeitiger Verdrehung der Scheibe dem jeweiligen Eckwinkel gemäß abgewinkelt wird, bis sich der letzte und der erste Abschnitt zum geschlossenen Rahmen endseitig zusammenfügen. Zur Vorbereitung des Abstandhalters braucht daher das gewünschte Hohlprofil, gegebenenfalls nach einer geeigneten Perforierung und Absorptionsmittelfüllung, ledig­lich dem Scheibenumfang entsprechend abgelängt zu werden, was durch verschiedenste Meßeinrichtungen, beispielsweise Lichtschranken u. dgl., problemlos und mit erforderlicher Genauigkeit durchführbar ist, und das eigentliche Fertig­stellen des Abstandhalters erfolgt während des Aufklebens auf die eine Einzelscheibe, wodurch zwangsweise die exakte Anpassung des Hohlprofilrahmens an die jeweilige Scheibe sichergestellt wird. Es sind weder aufwenidge Vorbereitungs­schritte noch umständliche Ausricht- und Zentriermaßnahmen zu ergreifen und, da der Profilstrang in den Rahmenschen­keln entsprechenden Abschnitten auf die Scheibe aufgesetzt und angeklebt wird, ist auch keine Beeinträchtigung der aufgebrachten Klebeschicht mit all den damit verbundenen Gefahren durch eine Scherbewegung zwischen Scheibe und Profil zu befürchten. Da vorzugsweise der Profilstrang klebemittelbeschichtet wird und nicht die Scheiben und der Profilstrang selbst durch seine Eigensteifigkeit keiner besonderen Führung bedarf, ist es unnötig, die zur maschi­nellen Durchführung des Verfahrens erforderlichen Einrich­tungen örtlich zusammenzudrängen, und die den Profilstrang vorbereitenden Einrichtungen, wie Beschichtungsdüsen, Schneideinrichtungen u. dgl., können mit genügendem Abstand von der Biegestelle angeordnet werden, welche Biegestelle vorteilhafterweise mit Führungs- und Biegebacken zum Ab­winkeln des Profilstranges und mit Schwenkeinrichtungen für das Verschwenken der Scheibe ausgerüstet ist, ohne daß es zu Platzproblemen kommt. Ist der Profilstrang ent­sprechend oft abgewinkelt und entlang allen Scheibenseiten­kanten aufgeklebt, stoßen die freien Enden des ersten und letzten Abschnittes aneinander, die zum Schließen des Rahmens durch Auftragen von Klebemittel oder durch Einsetzen einer eigenen Klammer miteinander verbunden werden. Ist der Hohlprofilrahmen auf der einen Scheibe fertig aufge­bracht, braucht lediglich in üblicher Weise die zweite Einzelscheibe deckungsgleich mit der ersten auf den Hohl­profilrahmen aufgeklebt zu werden und die einfache Isolier­glasscheibe ist fertig. Zur Herstellung einer Mehrfach-­Isolierglasscheibe wird der Vorgang des Einlegens des Ab­standhalters wiederholt, wobei nun die eine Einzelscheibe die vorhandene Isolierglasscheibe ist, auf die der Profil­strang abschnittsweise aufgeklebt werden muß. Da sich der Profilstrang beim Aufkleben und Abwinkeln ohne jede Zusatz­maßnahme an die jeweilige Scheibengröße und -form anpassen läßt, können auch beliebige Scheibenformate hergestellt werden, wobei nur eine Scheibenform mit ungeradlinigen Seitenkanten eine entsprechende Vorformung des Profilstran­ges verlangt.The invention solves this problem in that the hollow profile frame prepared as a continuous profile strand is glued to the pane edges in sections by angled the profile strand after gluing one section at a time to glue the following section while simultaneously rotating the pane in accordance with the respective corner angle until the Join the last and the first section to the end of the closed frame. To prepare the spacer, the desired hollow profile, if necessary after a suitable perforation and absorbent filling, only needs to be cut to length according to the pane, which can be achieved by means of a wide variety of measuring devices, for example light barriers and the like. Like., Can be carried out easily and with the required accuracy, and the actual completion of the spacer takes place during the gluing onto a single pane, which inevitably ensures the exact adaptation of the hollow profile frame to the respective pane. There are neither extensive preparation steps nor cumbersome alignment and centering measures to be taken and, since the section of the profile in the frame legs is attached and glued to the pane, there is no impairment of the applied adhesive layer with all the associated risks of a shear movement between the pane and Fear profile. Since the profile strand is preferably coated with adhesive and not the panes and the profile strand itself does not require any special guidance due to its inherent rigidity, it is unnecessary to locally press together the facilities required for the mechanical implementation of the method, and the facilities preparing the profile strand, such as coating nozzles, cutting devices and the like. Like., Can be arranged at a sufficient distance from the bending point, which bending point is advantageously equipped with guide and bending jaws for angling the profile strand and with pivoting devices for pivoting the disc, without causing space problems. If the profile strand is angled accordingly and glued along all the edges of the pane, the free ends of the first and last sections meet, which are connected to each other to close the frame by applying adhesive or by inserting a clip of their own. Once the hollow profile frame has been applied to the one pane, the second individual pane only has to be glued congruently to the first on the hollow profile frame and the simple insulating glass pane is finished. To produce a multiple insulating glass pane, the process of inserting the spacer is repeated, with the single insulating pane now being the existing insulating glass pane to which the profile strand must be glued in sections. Since the profile strand can be adapted to the respective pane size and shape when gluing and angling without any additional measure, any pane formats can also be produced, only one pane shape with uneven side edges requiring a corresponding preforming of the profile strand.

Günstig ist es, wenn erfindungsgemäß der Profilstrang spitz­winkelig zur Scheibe geführt und zum Aufkleben unter elasti­scher Verformung an die Scheibe angedrückt wird. Dadurch kann der Profilstrang Abschnitt für Abschnitt in die rich­tige Position relativ zur Scheibe gebracht werden, ohne beim Zuführen oder beim Abwinkeln an der Scheibe zu scheuern. Da der Profilstrang trotz seiner Steifigkeit elastisch bleibt, läßt sich der in Position gebrachte Profilstrangabschnitt zum Ankleben an die Scheibe andrük­ken, so daß eine sichere Klebung erreicht wird.It is expedient if, according to the invention, the profile strand is guided at an acute angle to the pane and is pressed onto the pane to adhere it with elastic deformation. Thereby the profile strand can be brought into the correct position relative to the pane, section by section, without rubbing against the pane during feeding or angling. Since the profile strand remains elastic in spite of its rigidity, the profile strand section which has been brought into position can be pressed onto the pane so that a secure bond is achieved.

Wird erfindungsgemäß der Profilstrang zwischen den benach­barten Abschnitten eingekerbt, kann das Abwinkeln erleich­tert werden und es kommt zu einer sauberen Eckausbildung des Hohlprofilrahmens. Außerdem läßt sich durch ein ent­sprechendes Kerben od. dgl. der Profilstrangenden der Pro­filhohlraum verschließen und ein Auslaufen des Adsorptions­mittels verhindern.If, according to the invention, the profile strand is scored between the adjacent sections, the angling can be facilitated and the corner profile of the hollow profile frame is neat. In addition, the profile cavity can be closed by a corresponding notch or the like. The profile extrusion ends and prevent leakage of the adsorbent.

An und für sich eignen sich die verschiedensten Profile, vor allem aber Aluminiumprofile, zur Herstellung des Ab­standhalters. Nach einer besonders vorteilhaften Ausge­staltung der Erfindung kann auch ein aus zwei Metall­streifen, vorzugsweise Aluminiumstreifen, zusammengesetzter Profilstrang verwendet werden, von welchem Metallstreifen der eine im Längsmittenbereich rinnenartig ausgeformt und der andere gelocht wird, worauf nach einer Adsorptions­mittelfüllung der Ausformung beide Metallstreifen aufein­andergelegt und durch Längsfalzung ihrer Ränder miteinander verbunden werden. Dieser zusammengesetzte Profilstrang läßt sich daher im Zuge der Isolierglasscheibenherstellung kontinuierlich fertigen, wobei als Ausgangsmaterial einfach zwei glatte Metallstreifen dienen, die dann durch entspre­chende Rollgänge automatisch geformt und auch miteinander verfalzt weden. Das Befüllen des Profils mit Adsorptions­mittel läßt sich ohne jede Schwierigkeit kurz vor dem Aufeinanderlegen und Verfalzen der Metallstreifen vornehmen, wobei der gelochte Metallstreifen die dem Isolierglasschei­ beninnenraum zugewandte Profilseitenfläche bildet. Die Metallstreifen können dünnwandig hergestellt sein und erlauben dadurch ein sauberes Abwinkeln beim Einlegen in die Einzelscheiben, wobei die für den Abstandhalter erforderliche Steifigkeit auf Grund der Profilierung und Verfalzung sicher gewährleistet wird.In and of itself, a wide variety of profiles, but especially aluminum profiles, are suitable for producing the spacer. According to a particularly advantageous embodiment of the invention, a profile strand composed of two metal strips, preferably aluminum strips, can be used, from which metal strip one is shaped like a groove in the longitudinal center region and the other is perforated, whereupon after an adsorbent filling of the formation, both metal strips are placed on top of one another and by longitudinally folding them Edges are joined together. This composite profile strand can therefore be manufactured continuously in the course of the production of insulating glass panes, with two smooth metal strips simply serving as the starting material, which are then automatically formed by corresponding roller tables and also folded together. The filling of the profile with adsorbent can be carried out without any difficulty shortly before the metal strips are laid on top of one another and folded, the perforated metal strip being the same as the insulating glass ben side space forms profile side surface. The metal strips can be made thin-walled and thus allow a clean angling when inserting them into the individual panes, the rigidity required for the spacer being guaranteed due to the profiling and interlocking.

Um Isolierglasscheiben auch bei Verwendung biegesteifer, stabiler Abstandhalter rationell herstellen zu können, wird der den Abstandhalter bildende Hohlprofilrahmen erst im Zuge der eigentlichen Isolierglasherstellung aus einem durchgehend vorbereiteten Profilstrang 1 gestaltet. Der Profilstrang 1 wird dazu in den Scheibenseiten ent­sprechenden Abschnitten 1a, 1b schrittweise auf eine der Einzelscheiben 2 der Isolierglasscheibe aufgeklebt, wobei der Profilstrang 1 in den Eckbereichen unter gleichzeitigem Verschwenken der Scheibe 2 abgewinkelt wird, was durch eine Vorrichtung 3 möglich ist, die Transportbänder 4 und eine zur Lotrechten etwas geneigte Stützwand 5, vorzugsweise Luftkissenwand, für die Führung und den Vorschub der Einzel­scheiben 2 aufweist. In einer Bearbeitungsstation 6 erfolgt das Aufkleben des Profilstranges 1 auf die Einzelscheiben 2, wobei der Profilstrang 1 parallel zur Förderbahn der Transportbänder 4, aber geringfügig spitzwinkelig zur Stütz­wand 5 an die Bearbeitungsstation 6 herangeführt wird. Der Profilstrang 1 durchläuft dabei eine der Bearbeitungs­station 6 vorgeordnete Vorbereitungsstation 7, die Beschich­tungsdüsen 8 zum Auftragen von Klebe- und Dichtungsmaterial auf den Profilstrang 1, eine Trennvorrichtung 9 zum Ablängen und eine Kerbvorrichtung 10 zur Einkerbung des Profil­stranges 1 umfaßt.In order to be able to produce insulating glass panes efficiently even when rigid, stable spacers are used, the hollow profile frame forming the spacer is designed from a continuously prepared profile strand 1 only in the course of the actual insulating glass production. For this purpose, the profile strand 1 is gradually glued in the sections 1a, 1b corresponding to the pane sides to one of the individual panes 2 of the insulating glass pane, the profile strand 1 being angled in the corner regions while the pane 2 is pivoted at the same time, which is possible by a device 3, the conveyor belts 4 and a support wall 5, preferably air cushion wall, slightly inclined to the vertical for guiding and advancing the individual disks 2. In a processing station 6, the profile strand 1 is glued to the individual disks 2, the profile strand 1 being brought parallel to the conveyor track of the conveyor belts 4, but at a slightly acute angle to the supporting wall 5, to the processing station 6. The profile strand 1 passes through a preparation station 7 arranged upstream of the processing station 6, the coating nozzles 8 for applying adhesive and sealing material on the extruded section 1, a separating device 9 for cutting to length and a notching device 10 for notching the extruded section 1.

Die Bearbeitungsstation 6 ist mit Andrückrollen 11 für ein sattes Andrücken des Profilstranges 1 an die jeweilige Einzelscheibe 2, Biegebacken 12 für das Abwinkeln des Pro­filstranges 1 und einem Schwenkarm 13 mit Saugern 14 zur Halterung und zum Schwenken der Scheibe 2 ausgerüstet.The processing station 6 is equipped with pressure rollers 11 for a tight pressing of the profile strand 1 onto the respective individual pane 2, bending jaws 12 for angling the profile strand 1 and a swivel arm 13 with suction cups 14 for holding and pivoting the pane 2.

Zum Herstellen einer Isolierglasscheibe wird nun eine Einzelscheibe 2 aus einer nicht weiter dargestellten Wasch­anlage nach Passieren einer Vermessungseinrichtung stehend der Stützwand 5 entlang auf den Transportbändern 4 zur Bearbeitungsstation 6 gebracht, während gleichzeitig ein Profilstrang 1 zugeführt wird, der in der Vorbereitungs­station 7 beidseitig mit Klebemittel beschichtet und ent­sprechend den Seitenlängen bzw. dem Scheibenumfang einge­kerbt und abgelängt wurde. In der Bearbeitungsstation 6 werden Scheibe 2 und Profilstrang 1 synchron zueinander bewegt und dabei der Profilstrang 1 über die Andrückrollen 11 unter elastischer Verbiegung angedrückt, so daß eine satte Verklebung zwischen Scheibe 2 und Abstandhalter 1 erfolgt. Nach dem Aufkleben des Profilstrangabschnittes 1a entlang der ersten Seitenkante stoppt der Vorschub und der Profilstrang 1 wird konform mit dem Verschwenken der Scheibe 2 um 90° abgewinkelt. Die Biegebacken 12 führen diese Abwinkelung exakt durch, wobei die Einkerbungen im Profilstrang 1 eine saubere Eckausbildung erlauben. Das Verschwenken der Scheibe 2 erfolgt über den Schwenkarm 13, der mit seinen Saugern 14 die Scheibe 2 erfaßt und ebenfalls um genau 90° verschwenkt, bis sie mit der zweiten Seite auf den Transportbändern 4 aufsetzt. Der Vorschub beginnt wieder und der Abschnitt 1b des Profilstranges 1 wird entlang der zweiten Scheibenkante aufgeklebt, wobei erneut die Andrückrollen 11 für ein sattes Anpressen des Stranges 1 an der Scheibe 2 sorgen. Anschließend an dieses Aufkleben des Profilstrangabschnittes 1b erfolgt wiederum unter gleichzeitigem Verschwenken der Scheibe 2 das Abwin­keln des Profilstranges 1, dann das Ankleben des nächsten Abschnittes usw. bis der Profilstrang 1 entlang aller Seitenkanten der Scheibe 2 aufgeklebt ist, worauf die aneinanderstoßenden Strangenden durch Klebemasse oder durch ein geeignetes Endstück zum geschlossenen Hohlprofilrahmen verbunden werden.To produce an insulating glass pane, a single pane 2 is then brought from a washing installation (not shown further) after passing a measuring device upright along the support wall 5 on the conveyor belts 4 to the processing station 6, while at the same time a profile strand 1 is supplied, which is coated on both sides in the preparation station 7 with adhesive and was notched and cut to length according to the side lengths or the disk circumference. In the processing station 6, the disk 2 and the extruded section 1 are moved synchronously with one another and the extruded section 1 is pressed by the pressure rollers 11 with elastic bending, so that there is a good bond between the disk 2 and the spacer 1. After the profile strand section 1a has been glued along the first side edge, the feed stops and the profile strand 1 is angled 90 ° in conformity with the pivoting of the disk 2. The bending jaws 12 perform this bend exactly, the notches in the profile strand 1 allowing a clean corner formation. The disc 2 is pivoted via the swivel arm 13, which grips the disc 2 with its suction cups 14 and also pivots by exactly 90 ° until it touches the conveyor belts 4 with the second side. The feed begins again and section 1b of the profile strand 1 is glued along the second edge of the disc, whereby again the pressure rollers 11 ensure a tight pressing of the strand 1 on the disc 2. Subsequent to this gluing of the profile strand section 1b, the profile strand 1 is then angled while simultaneously pivoting the pane 2, then the next section is glued, etc. until the profile strand 1 is glued along all the side edges of the pane 2, whereupon the abutting strand ends by adhesive or by a suitable end piece can be connected to the closed hollow profile frame.

Die Scheibe 2 mit dem nun aufgeklebten und zum Hohlprofil­rahmen gewinkelten Profilstrang 1 wird aus der Bearbeitungs­station 6 abtransportiert, worauf zur Fertigstellung der Isolierglasscheibe nur mehr die zweite Einzelscheibe durch Aufsetzen und Andrücken auf den klebemittelbeschichteten Hohlprofilrahmen aufgeklebt zu werden braucht.The pane 2 with the profile strand 1 now glued on and angled to the hollow profile frame is transported away from the processing station 6, whereupon only the second individual pane needs to be glued to the adhesive-coated hollow profile frame by placing and pressing on it to complete the insulating glass pane.

Wie vor allem aus Fig. 2 hervorgeht, kann zur weiteren Rationalisierung und Automatisierung der Isolierglasher­stellung der Profilstrang 1 aus zwei Metallstreifen 15, 16 zusammengesetzt sein, von denen der Metallstreifen 15 im Längsmittenbereich eine rinnenförmige Ausformung 15a und der Metallstreifen 16 eine Lochung 16a aufweisen. Da die Metallstreifen 15, 16 durch Längsfalzungen 17 an den Rändern miteinander verbunden sind, läßt sich damit auch der Profilstrang 1 selbst im Zuge der Isolierglasherstellung kontinuierlich fertigen, da die Metallstreifen 15, 16 ohne Schwierigkeiten durch entsprechende Rollgänge od. dgl. vorgeformt und verfalzt werden können und vor dem Zusammen­fügen der beiden Metallstreifen 15, 16 auch die Ausformung 15a problemlos mit Adsorptionsmittel 18 befüllbar ist, das dann durch die Lochung 16a vom Innenraum der Isolier­glasscheibe luftzugänglich ist.As can be seen above all from FIG. 2, for further rationalization and automation of the production of insulating glass, the profile strand 1 can be composed of two metal strips 15, 16, of which the metal strip 15 has a channel-shaped shape 15a in the longitudinal center region and the metal strip 16 has a perforation 16a. Since the metal strips 15, 16 are connected to one another at the edges by longitudinal folds 17, the profile strand 1 can thus also be produced continuously in the course of the production of insulating glass, since the metal strips 15, 16 are preformed and folded without difficulty by corresponding roller tables or the like can and before joining the two metal strips 15, 16, the formation 15a can be easily filled with adsorbent 18, which is then accessible through the perforation 16a from the interior of the insulating glass pane.
