Abstract

An insulating glass pane structure including two glass panes is formed by providing an elastoplastic strip from a delivery reel, where the elastoplastic strip has a varying dimension along its width including a first, nominal width section and a second, reduced width section that is smaller in width than the nominal width section. Side surface area portions of the nominal width section of the strip are coated with a first adhesive glue, and side surface area portions of the reduced width section of the strip are coated with a second adhesive glue that is diffusion-proof against water vapor. One side surface of the strip is pressed against a first glass pane to form a spacer, the strip being pressed close to an edge of the first glass pane, and the second glass pane is applied and pressed to form the glass pane structure.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Isolierglasscheiben aus wenigstens zwei Glasplatten, zwischen denen ein elastoplastisches Band als Abstandhalter angeordnet ist.The invention relates to a method and an apparatus for producing insulating glass panes from at least two glass plates, between which an elastoplastic strip is arranged as a spacer.

Üblicherweise bestehen die Abstandhalter zwischen einer zwei oder auch mehr Glasscheiben umfassenden Isolierglaseinheit aus Aluminium- oder Stahlhohlprofilen.Usually, the spacers between a two or more glass panes comprising insulating glass unit made of aluminum or steel hollow sections.

Aus der US-A-3 399 294 ist eine beheizte Isolierglasscheibe bekannt, deren Abstandhalter aus Aluminium- oder Kunststoffhohlprofilen zusammengesetzt ist und einen (schwach) gestuften Rechteckquerschnitt hat. Die zur Anlage an der ersten und der zweiten Glasplatte bestimmten, streifenförmigen Seitenflächen sind zur vorläufigen Fixierung des Abstandhalters jeweils mit einem transparenten Klebeband versehen. Die nach außen weisende Fläche des Abstandhalterrahmens ist bündig mit den äußeren Rändern der Glasplatten. Diese und die zwischen dem Abstandhalterrahmen und der jeweiligen Glasplatte verbleibenden Spalte sind zur diffusionsdichten Abdichtung einheitlich mit einem Thiokolkleber überzogen bzw. ausgespritzt.From the U.S.-A-3,399,294 a heated insulating glass pane is known, the spacer of aluminum or plastic hollow profiles is composed and has a (weak) stepped rectangular cross-section. The strip-shaped side surfaces intended to rest against the first and the second glass plate are each provided with a transparent adhesive tape for provisional fixing of the spacer. The outwardly facing surface of the spacer frame is flush with the outer edges of the glass plates. These and the remaining between the spacer frame and the respective glass plate column are uniformly coated or sprayed with a Thiokolkleber for diffusion-tight sealing.

Aus der DE-A-30 02 904 ist jedoch auch schon ein häufig als "Swiggle-Strip" bezeichneter Abstandhalter in Form eines Bandes mit Rechteckquerschnitt bekannt, das, mit Schutzfolien versehen, von einer Vorratstrommel oder -haspel kommt und mittels einer mit einem wendbaren Kopf ausgestatteten Vorrichtung auf die Glasscheibe aufgebracht wird. Dieser bandförmige Abstandhalter auf der Basis von Butylkautschuk ist zäh-plastisch, stark klebend (was zur Erzielung einer gasdichten Verbindung zunächst mit der ersten und später der zweiten Glasscheibe der Isolierglaseinheit erwünscht ist), hat aber eine stark temperaturabhängige Viskosität.From the DE-A-30 02 904 however, it is also already known as a "swiggle strip" spacer in the form of a strip with a rectangular cross-section, which, provided with protective films, from a storage drum or reel comes and is applied by means of a reversible head equipped device on the glass. This band-shaped spacer on the basis of butyl rubber is tough-plastic, highly adhesive (which is desirable to achieve a gas-tight connection first with the first and then the second glass of the insulating glass unit), but has a strong temperature-dependent viscosity.

In jüngerer Zeit sind wesentlich weniger temperaturempfindliche elastoplastische Abstandhalterbänder auf der Basis von Polyurethan oder Ähnlichem entwickelt worden, die ebenfalls Rechteckquerschnitt haben, form- und abmessungsbeständiger als der sogenannte "Swiggle-Strip" sind, auf der späteren Außenseite eine Kaschierung aus Aluminiumfolie haben und auf den beiden zur Verklebung mit den Glasscheiben bestimmten Schmalseiten herstellerseitig mit einer dünnen, bis zum Applizieren mit Schutzfolien abgedeckten Beschichtung aus einem stark adhäsiven Kleber versehen sind. Aus der DE-A-102 12 359 sind ein Verfahren und eine Vorrichtung zum Applizieren eines derartigen Bandes auf wenigstens die erste Glasplatte einer aus wenigstens zwei solcher Glasplatten bestehenden Isolierglaseinheit bekannt.More recently, substantially less temperature-sensitive elastomeric spacer tapes based on polyurethane or the like have been developed, which also have a rectangular cross-section, are dimensional and dimensionally stable than the so-called "swiggle strip" on which later outer side have a lamination of aluminum foil and on the two sides intended for bonding with the glass sheets narrow sides are provided by the manufacturer with a thin, covered to apply with protective films coating of a highly adhesive adhesive. From the DE-A-102 12 359 For example, a method and a device for applying such a strip to at least the first glass plate of an insulating glass unit consisting of at least two such glass plates are known.

Diesseits wurde jedoch festgestellt, dass der auf den beiden Schmalseiten des Bandes aufgetragene Kleber nicht wasserdampfdiffusionsdicht ist. Vermutlich handelt es sich um einen rasch auspolymerisierenden Kleberlack auf der Basis von Methacrylaten. Deshalb wurde bisher nach dem Zusammenbau der Isolierglasscheibe die verbleibende Randfuge mit einer Dichtmasse ausgefüllt, die die zwingend erforderliche Wasserdampfdiffusionsdichtigkeit gewährleistet, weil anderenfalls im Laufe der Zeit Wasserdampf in den abgeschlossenen Innenraum der Isolierglasscheibe eindringt und unvermeidbar zu Bildung von Kondenswasser und damit zur Unbrauchbarkeit der Scheibe führt. Geeignete Randfugenfüllmassen sind jedoch teuer und werden wegen des erheblichen Querschnittes der Randfuge in großen Mengen benötigt.On this side, however, it was found that the adhesive applied to the two narrow sides of the strip is not water vapor diffusion tight. Presumably, it is a rapidly polymerizing adhesive varnish based on methacrylates. Therefore, the remaining edge joint has been filled with a sealant so far after assembly of the insulating glass, which ensures the absolutely necessary Wasserdampfdiffusionsdichtigkeit, otherwise water vapor in the closed interior of the insulating glass penetrates over time and inevitably leads to the formation of condensation and thus the uselessness of the disc , However, suitable Randfugenfüllmassen are expensive and are needed in large quantities because of the considerable cross-section of the edge joint.

In der diesseitigen, älteren, nicht vorveröffentlichten deutschen Patentanmeldung Nr. 103 50 312.9 ist ein demgegenüber vorteilhafteres Verfahren beschrieben, das mit dem gleichen elastoplastischen Band, das jedoch auf den beiden Schmalseiten nicht mit dem genannten Kleber beschichtet ist, arbeitet. Auf die Schmalseiten des Bandes wird erst kurz vor dessen Applizieren auf die Glasplatte ein wasserdampfdiffusionsdichter Kleber, vorzugsweise ein Butylkleber, aufgetragen. Es hat sich jedoch gezeigt, dass es anders als bei den seit langem bekannten und allgemein üblichen, starren Abstandhalterrahmen mit butylbeschichteten Seitenflächen in Folge der begrenzten Adhäsionskräfte des Butylklebers insbesondere bei im Verhältnis zu ihrer Dicke breiten Bändern und/oder bei großen Scheibenformaten und entsprechend langen Bändern dazu kommen kann, dass das auf die erste Glasplatte applizierte Band schon vor dem Aufsetzen der zweiten Glasplatte und/oder bei dem Verpressen der beiden Glasplatten zu der Isolierglaseinheit stellenweise wandert, sich also um geringe Beträge aus der Solllage entfernt. Dies kann zu optischen Beeinträchtigungen der fertigen Isolierglaseinheit durch ein "welliges" Aussehen des Abstandhalters und/oder nicht exakt rechtwinklige Ausbildungen der Ecken des Abstandhalters führen. Insbesondere aus Gründen einer besseren Wärmeisolierung im Verhältnis zu metallischen Abstandhaltern besteht jedoch das Bestreben, anstelle letzterer geeignete Kunststoffbänder einzusetzen.In this page, older, not pre-published German Patent Application No. 103 50 312.9 In contrast, a more advantageous method is described, which works with the same elastoplastic tape, but which is not coated on the two narrow sides with said adhesive. On the narrow sides of the tape, a water vapor diffusion-tight adhesive, preferably a butyl adhesive is applied shortly before its application to the glass plate. However, it has been shown that unlike the long-known and common, rigid spacer frames with butyl-coated Side surfaces due to the limited adhesion forces of the butyl adhesive in particular in relation to their thickness broad bands and / or large disc formats and correspondingly long bands can come to that applied to the first glass plate band before placing the second glass plate and / or at the pressing of the two glass plates to the insulating glass unit moves in places, so it is removed by small amounts from the desired position. This can lead to optical impairments of the finished insulating glass unit by a "wavy" appearance of the spacer and / or not exactly rectangular configurations of the corners of the spacer. However, in particular for reasons of better thermal insulation in relation to metallic spacers, there is a desire to use instead of the latter suitable plastic bands.

Der Erfindung liegt die Aufgabe zugrunde, dieses letztgenannte Verfahren zu verbessern und eine insbesondere zur Durchführung des verbesserten Verfahrens geeignete Vorrichtung zu schaffen.The invention has for its object to improve this latter method and to provide a device particularly suitable for carrying out the improved method.

Verfahrensmäßig ist diese Aufgabe durch die im Patentanspruch 1 bzw. 2 angegebenen Schritte gelöst.In terms of method, this object is achieved by the steps specified in patent claims 1 and 2, respectively.

Anders als im Stand der Technik wird also von einem elastoplastischen Band nicht mit normalem Rechteckquerschnitt sondern mit einem (schwach) gestuften Rechteckquerschnitt oder auch einem Trapezquerschnitt ausgegangen. Jede der beiden Seitenflächen besteht deshalb aus zwei streifenförmigen Teilflächen, von denen die der größeren Breite des Bandes entsprechende Teilfläche vorzugsweise bereits herstellerseitig mit dem stark adhäsiven Kleber mit einer Schichtstärke von normalerweise deutlich weniger als 1/10 mm beschichtet wird, während die andere, demgegenüber zurückgesetzte oder tieferliegende streifenförmige Teilfläche dann im Anlieferzustand des Bandes kleberfrei ist. Kurz vor dem Applizieren des Bandes wird auf die beidseitigen, tieferliegenden streifenförmigen Teilflächen der Seitenflächen ein zweiter Kleber aufgetragen, der die notwendige Wasserdampfdiffusionsdichtigkeit gewährleistet. Die Schichtdicke dieses Klebers liegt normalerweise im Bereich von einigen zehntel Millimetern. Um diese Schichtdicke ist das Band im Bereich der beidseitigen Teilflächen schmaler, so dass der Auftrag des zweiten Klebers die Stufe zwischen den beiden Teilflächen mindestens etwa ausgleicht. Beim Applizieren des Bandes auf die Glasscheibe gewährleistet der stark adhäsive, filmartige Kleber, dass das Band exakt und unverrückbar in seiner vorgegebenen Lage auf der ersten Glasscheibe haftet und der zweite Kleber sorgt für die diffusionsdichte Verbindung des Bandes bzw. Abstandhalters mit der Glasscheibe. Das gleiche gilt für das Aufsetzen der zweiten Glasscheibe und das Verpressen der Einheit. Anschließend wird die verbleibende Randfuge wie bisher mit einer Dichtmasse ausgefüllt, die jedoch nicht wasserdampfdiffusionsdicht sein muss und daher preiswerter als die bisher benötigten Dichtmassen sein kann.Unlike in the prior art, it is therefore assumed that an elastoplastic strip does not have a normal rectangular cross section but a (weakly) stepped rectangular cross section or a trapezoidal cross section. Each of the two side surfaces therefore consists of two strip-shaped partial surfaces, of which the part of the larger width of the band corresponding surface is preferably already factory-coated with the highly adhesive adhesive with a thickness of usually much less than 1/10 mm, while the other, on the other hand, reset or deeper strip-shaped partial surface then in the delivery state of the tape is adhesive-free. Shortly before the application of the tape, a second adhesive is applied to the bilateral, deeper-lying strip-shaped partial surfaces of the side surfaces, which ensures the necessary water vapor diffusion tightness. The layer thickness of this adhesive is usually in the range of a few tenths of a millimeter. To this layer thickness, the band is narrower in the region of the two-sided partial surfaces, so that the application of the second adhesive at least approximately equalizes the step between the two partial surfaces. When applying the tape to the glass, the highly adhesive, film-like adhesive ensures that the tape adheres exactly and immovably in its predetermined position on the first glass and the second adhesive ensures the diffusion-tight connection of the tape or spacer with the glass. The same applies to the placement of the second glass pane and the compression of the unit. Subsequently, the remaining edge joint is filled as before with a sealant, but which does not have to be water vapor diffusion tight and therefore can be cheaper than the previously required sealing compounds.

Bevorzugt wird als Kleber ein Butylkleber verwendet , wie er sich schon zur Beschichtung der Seitenflächen der genannten Abstandhalterrahmen aus Metallhohlprofilen bewährt hat.Preferably, a butyl adhesive is used as the adhesive, as he has already proven to coat the side surfaces of said spacer frame made of metal hollow sections.

Bei dem Verfahren nach der Erfindung wird das Band vorzugsweise mittels einer selbsttätig arbeitenden Applizierstation auf die erste Glasscheibe aufgesetzt und an diese angedrückt .In the method according to the invention, the band is preferably placed on the first glass pane by means of an automatically operating application station and pressed against it.

Die auf das Band aufgetragene Menge an Kleber wird zweckmäßig in Abhängigkeit von der Bandtransportgeschwindigkeit geregelt , uzw. so, dass sich eine möglichst konstante Kleberschichtdicke ergibt. Das lässt sich dadurch erreichen, dass die je Zeiteinheit für den Auftrag verbrauchte Klebermenge proportional zur Bandtransportgeschwindigkeit gehalten wird, also insbesondere bei Stillstand des Bandes auf Null geht.The applied to the tape amount of adhesive is suitably regulated as a function of the tape transport speed, uzw. so that the result is a very constant adhesive layer thickness. That's possible achieve that the amount of adhesive consumed per unit of time for the job is kept proportional to the tape transport speed, that is to say zero, in particular when the tape is at a standstill.

Idealerweise wird die Dicke der Kleberbeschichtung unabhängig von der Transportgeschwindigkeit etwa konstant gehalten.Ideally, the thickness of the adhesive coating is kept approximately constant regardless of the transport speed.

Letzteres kann vor allem in der Weise erreicht werden, dass der IST-Wert der Dicke der Beschichtung gemessen und die Abweichung von einem vorgegebenene SOLL-Wert als Fehlersignal zur Konstanthaltung der Beschichtungsdicke benutzt wird. Geeignete Schichtdickenmessverfahren sind an sich bekannt.The latter can be achieved, above all, in such a way that the actual value of the thickness of the coating is measured and the deviation from a predefined setpoint value is used as an error signal for keeping the coating thickness constant. Suitable layer thickness measuring methods are known per se.

Die der Erfindung zugrundeliegende Aufgabe ist im Weiteren mit einer Vorrichtung, die eine Vorratshaspel für das Band, mehrere angetriebene Bandführungsrollen und einen relativ zu einer ersten Glasscheibe beweglichen Andrückkopf für das Band umfasst, dadurch gelöst, dass zwischen der Vorratshaspel und dem Andrückkopf einander gegenüberliegende Düsen zur Beschichtung der tieferliegenden, streifenförmigen Teilflächen der Seitenflächen des Bandes mit einem wasserdampfdiffusionsdichten Kleber angeordnet sind (Anspruch 7).The object underlying the invention is further achieved by a device comprising a supply reel for the band, a plurality of driven tape guide rollers and a movable relative to a first glass pressure head for the tape, characterized in that between the supply reel and the pressure head opposing nozzles for Coating the deeper, strip-shaped faces of the side surfaces of the belt are arranged with a water vapor diffusion-tight adhesive (claim 7).

Den Beschichtungsdüsen sind Mittel zur Steuerung des Kleberdurchflusses in Abhängigkeit von der Bandtransportgeschwindigkeit zugeordnet.The coating nozzles are assigned means for controlling the adhesive flow as a function of the belt transport speed.

Dabei kann, bezogen auf die Bandtransportrichtung, vor den Beschichtungsdüsen mindestens ein erstes Rollenpaar zur seitlichen Führung des Bandes angeordnet sein.In this case, based on the tape transport direction, before the coating nozzles at least a first pair of rollers for the lateral guidance of the tape can be arranged.

Ergänzend kann, bezogen auf die Bandtransportrichtung, vor den Beschichtungsdüsen eine Höhenführung für das Band angeordnet sein, die gegebenenfalls nur aus einem einfachen, waagerechten Unterstützungssteg, einer Unterstützungsrolle, auf der das Band aufliegt oder aus einem Rollenpaar, zwischen dem das Band hindurchläuft, bestehen kann.In addition, based on the tape transport direction, before the coating nozzles a height guide for the band may be arranged, which may consist only of a simple, horizontal support web, a support role on which the tape rests or from a pair of rollers, between which the tape passes, if necessary.

Wenn die Beschichtungsstation nicht in den Andrückkopf integriert ist, können, bezogen auf die Bandtransportrichtung, auch nach den Beschichtungsdüsen zur seitlichen Führung des Bandes Rollenpaare angeordnet sein, deren Rollen dann zweckmäßig das Band nur an den Kanten der Bandseitenflächen berühren, um eine Verschmutzung der Rollen durch die frisch aufgetragene Kleberschicht sowie umgekehrt die Beschädigung letzter zu vermeiden.If the coating station is not integrated in the pressure head, can be arranged based on the tape transport direction, even after the coating nozzles for lateral guidance of the tape roller pairs whose roles then suitably touch the tape only at the edges of the belt side surfaces to contamination of the rollers the freshly applied adhesive layer and vice versa to avoid the damage last.

Bei exakter Dosierung kann auf jede der Teilflächen der Seitenflächen des Bandes mittig ein Kleberstrang aufgetragen werden, dessen Querschnitt so bemessen ist, dass sich beim Andrücken des Bandes an die erste Glasscheibe bzw. beim Andrücken der zweiten Glasscheibe an die andere Seitenfläche des Bandes eine gleichmäßige Kleberschicht ausbildet, ohne dass Kleber über die Kanten der Bandseitenflächen quillt. In der Regel ist es jedoch einfacher, die Beschichtungsdüsen als Schlitzdüsen auszubilden.With exact dosing can be applied to each of the partial surfaces of the side surfaces of the tape centrally a strand of adhesive whose cross-section is dimensioned so that when pressing the tape to the first glass or when pressing the second glass to the other side surface of the tape a uniform adhesive layer forms without glue over the edges of the belt side surfaces swells. In general, however, it is easier to form the coating nozzles as slit nozzles.

In diesem Fall kann die Schlitzbreite der Beschichtungsdüsen kleiner als die Breite der betreffenden Teilflächen der Seitenflächen des Bandes sein, so dass unter der Voraussetzung eines nicht zu reichlichen Kleberauftrages die jeweilige Beschichtung nicht ganz bis an die Kanten der Bandseitenflächen reicht. Dadurch wird erreicht, dass weitere seitliche Führungsmittel, beispielsweise die zuvor genannten Rollenpaare bei geeigneter, z.B. V-förmiger Profilierung nicht mit der klebenden Beschichtung in Berührung kommen und daher nicht verschmutzen. Schließlich kann, bezogen auf die Handtransportrichtung, nach den Beschichtungsdüsen eine Einrichtung zur Messung der Dicke der Beschichtung angeordnet sein, die den Kleberdurchfluss durch die Beschichtungsdüsen regelt.In this case, the slit width of the coating nozzles may be smaller than the width of the relevant partial surfaces of the side surfaces of the belt, so that on the condition of not too abundant adhesive application, the respective coating does not reach all the way to the edges of the belt side surfaces. This ensures that other lateral guide means, for example, the above-mentioned pairs of rollers with suitable, for example, V-shaped profiling do not come into contact with the adhesive coating and therefore do not pollute. Finally, with respect to the hand transport direction, after the coating nozzles, a device for measuring the thickness of the coating can be arranged, which regulates the adhesive flow through the coating nozzles.

Gemäß Figur 1 wird ein elastoplastisches Band 1 mit dem in Fig. 2 dargestellten, gestuften Rechteckquerschnitt von einer Vorratshaspel 2, die auf einer angetriebenen Welle 3 sitzt, über eine Wegmesseinrichtung 4 und angedeutete Führungsrollen 5 abgezogen. Die beiden Seitenflächen des unten anhand Fig. 2 bis 4 näher beschriebenen Bandes 1 sind mit je einer Schutzfolie 1a, 1b (vgl. Fig. 2) abgedeckt, die vor oder nach der Wegmesseinrichtung 4 abgezogen und zur Entsorgung aufgewickelt werden. Dies ist bekannt und daher nicht dargestellt. Das Band 1 läuft in eine Beschichtungsstation 10, die über eine Leitung 14 mit einer Pumpe 15 auf einem einen Butylkleber enthaltenden Behälter 13 verbunden ist. Auf die Beschichtungsstation 10, in der auf die beiden Seitenflächen des Bandes je ein schmaler Streifen aus einer Butylkleberschicht aufgetragen wird, folgt ein Rollenpaar 6 zur seitlichen Führung des beschichteten Bandes. Daran schließt sich eine Strecke an, in welcher das Band 1 frei durchhängt. Der Durchhang wird durch einen unteren Sensor 30 und einen oberen Sensor 31, die über die angedeuteten Signalkabel mit der Maschinensteuerung (nicht dargestellt) verbunden sind, zwischen einem (oberen) Minimalwert und einem (unteren) Maximalwert gehalten, uzw. in der Weise, dass die Maschinensteuerung in Abhängigkeit von den Signalen der Sensoren 30 und 31 auf die entsprechenden Haspelund Rollenantriebe einwirkt. Dadurch wird erreicht, dass das Band ohne Längsspannungen, d.h. weder gestaucht noch gedehnt, über weitere Rollenpaare wie 7 und 8 anschließend in einen nur angedeuteten Applizier- oder Andrückkopf 20 einläuft, der über einen Schlitten 21 in Richtung des Doppelpfeiles auf einer Säule 22 verfahrbar ist. Die Säule 22 ist leicht gegen die Vertikale geneigt und parallel zu einer üblichen Stützwand 23, z.B. einer Luftkissenstützwand, die auf einem Maschinengestell 24 ruht. Gegen die Stützwand 23 lehnt eine Glasplatte 40, deren Unterrand auf dem angedeuteten Rollenförderer 25 aufsteht. Mittels dessen oder mittels eines Unterdruckförderers 26 an sich bekannter Art, der auf Horizontalholmen 27 verschiebbar ist, ist die Glasplatte 40 reversierend transportierbar. Der Andrückkopf 20 ist seinerseits um eine zur Säule 22 rechtwinklige Achse wendbar. Durch entsprechend gesteuerte Relativverschiebung des Andrückkopfes 20 gegenüber der Glasplatte 40 wird das Band 1 randnah umlaufend an die Glasplatte 40 angedrückt, wie dies an sich bekannt ist.According to FIG. 1 is an elastoplastic tape 1 with the in Fig. 2 illustrated, stepped rectangular cross-section of a supply reel 2, which sits on a driven shaft 3, deducted via a displacement measuring device 4 and indicated guide rollers 5. The two side surfaces of the bottom are based Fig. 2 to 4 Tape 1 described in more detail, each with a protective film 1a, 1b (see. Fig. 2 ), which are deducted before or after the displacement measuring device 4 and the Disposal can be wound up. This is known and therefore not shown. The belt 1 passes into a coating station 10, which is connected via a line 14 to a pump 15 on a container 13 containing a butyl adhesive. On the coating station 10, in each of which a narrow strip of a Butylkleberschicht is applied to the two side surfaces of the tape, followed by a pair of rollers 6 for lateral guidance of the coated tape. This is followed by a track in which the band 1 sags freely. The slack is held by a lower sensor 30 and an upper sensor 31, which are connected via the indicated signal cables with the machine control (not shown), between a (upper) minimum value and a (lower) maximum value, uzw. in that the machine controller acts on the respective reel and reel drives in response to the signals from the sensors 30 and 31. This ensures that the band without longitudinal stresses, ie neither compressed nor stretched, then passes over further pairs of rollers such as 7 and 8 in an only indicated Applizier- or Andrückkopf 20 which is movable via a carriage 21 in the direction of the double arrow on a column 22 , The column 22 is slightly inclined to the vertical and parallel to a conventional support wall 23, for example an air cushion support wall resting on a machine frame 24. Against the support wall 23 leans a glass plate 40, the lower edge of which rests on the indicated roller conveyor 25. By means of this or by means of a vacuum conveyor 26 in a known manner, which is displaceable on horizontal bars 27, the glass plate 40 is reversibly transportable. The pressure head 20 is in turn turnable about a right angle to the column 22 axis. By appropriately controlled relative displacement of the pressure head 20 relative to the glass plate 40, the tape 1 is pressed peripherally circumferentially to the glass plate 40, as is well known.

In einer nicht dargestellten, aufwändigeren Ausführungsform umfasst die Vorrichtung auch eine Station zum Aufbringen des stark adhäsiven, filmartigen Klebers 50 in Fig. 2 und folgende. Dann wird das Band kleberfrei und ohne Schutzfolien angeliefert. Davon unabhängig kann die Beschichtungsstation 10 auch in den Andrückkopf 20 integriert sein, sodaß die Beschichtung mit dem Butylkleber erst unmittelbar vor dem Andrücken des Bandes an die Glasplatte 40 erfolgt.In a non-illustrated, more elaborate embodiment, the apparatus also includes a station for applying the highly adhesive film-like adhesive 50 in FIG Fig. 2 and the following. Then the tape is delivered glue-free and without protective films. Irrespective of this, the coating station 10 can also be integrated in the pressing head 20, so that the coating with the butyl adhesive takes place only immediately before the band is pressed against the glass plate 40.

Figur 2 zeigt einen Querschnitt durch das Band 1 im Anlieferzustand, also in der Regel aufgerollt auf der Haspel 2 in Figur 1. Das Band hat einen schwach gestuften Rechteckquerschnitt. Die Darstellung ist nicht maßstäblich. Jede der beiden Seitenflächen ist in eine streifenförmige Teilfläche 1.1 und eine daran anschließende und um wenige zehntel Millimeter zurückgesetzte bzw. tieferliegende Teilfläche 1.2 gegliedert. Auf jeder der Teilflächen 1.1 befindet sich eine sehr dünne Schicht eines Klebers 50, der ein sehr hohes Adhäsionsvermögen hat und nach dem Abziehen der schon erwähnten Schutzfolien 1a, 1b auf Glas stark haftet. Die Teilflächen 1.1 und 1.2 können, wie dargestellt, etwa gleich breit sein. Bei ausreichend hoher Adhäsionskraft des Klebers 50 kann der Streifen 1.1 jedoch auch schmaler zugunsten einer größeren Breite des Streifens 1.2 sein. Der dargestellte, gestufte Rechteckquerschnitt ist beispielhaft. Das Band kann auch den in Figur 2a dargestellten, doppelt gestuften oder genuteten Querschnitt haben, wobei die Nut anstelle des dargestellten Rechteckquerschnittes auch als Hohlkehle ausgebildet sein kann. Grundsätzlich in Betracht kommt auch der in Figur 2b dargestellte, schwach trapezförmige Querschnitt. FIG. 2 shows a cross section through the belt 1 in the delivery condition, so usually rolled up on the reel 2 in FIG. 1 , The band has a slightly stepped rectangular cross-section. The representation is not to scale. Each of the two side surfaces is divided into a strip-shaped partial surface 1.1 and an adjoining and set back by a few tenths of a millimeter or deeper partial surface 1.2. On each of the faces 1.1 is a very thin layer of adhesive 50, which has a very high adhesiveness and after peeling off the already mentioned protective films 1a, 1b strongly adheres to glass. The faces 1.1 and 1.2 can, as shown, be about the same width. However, with sufficiently high adhesive strength of the adhesive 50, the strip 1.1 may be narrower in favor of a larger width of the strip 1.2. The illustrated, stepped rectangular cross section is exemplary. The band can also do the in FIG. 2a shown, double stepped or grooved cross section, wherein the groove may be formed instead of the illustrated rectangular cross section as a groove. Basically into consideration is also the in FIG. 2b shown, slightly trapezoidal cross-section.

Figur 3 zeigt schematisch die in der Beschichtungsstation 10 angeordneten Düsen 11 und 12 zum Auftrag des Butylklebers auf die tiefer liegenden streifenförmigen Teilflächen der Seitenflächen des Bandes 1. Der Durchfluss des Butylklebers durch jede der Düsen 11 und 12 ist mittels über Stellmotore angetriebener Schieber 11.1 und 12.1 in der Weise steuer- oder regelbar, dass die Seitenflächen des Bandes 1 mit je einer Kleberschicht 60 im Wesentlichen konstanter, d.h. von der Augenblicksgeschwindigkeit des Bandes 1 unabhängiger Dicke beschichtet werden. Hierzu sind die Antriebsmotoren der Schieber 11.1 und 12.1 und gegebenenfalls nachgeordnete Dickenmesseinrichtungen mit der Maschinensteuerung verbunden (nicht dargestellt). Die Düsen sind zur Anpassung des Abstandes ihrer Mündungen an Bänder unterschiedlicher Breite entsprechend den Doppelpfeilen verschiebbar. FIG. 3 schematically shows the arranged in the coating station 10 nozzles 11 and 12 for applying the butyl adhesive to the deeper strip-shaped faces of the side surfaces of the belt 1. The flow of the butyl adhesive through each of the nozzles 11 and 12 is controlled by means of actuators driven slide 11.1 and 12.1 in such a way that the side surfaces of the belt 1, each with an adhesive layer 60 substantially constant, ie independent of the instantaneous speed of the belt 1 thickness are coated , For this purpose, the drive motors of the slide 11.1 and 12.1 and optionally downstream thickness gauge devices are connected to the machine control (not shown). The nozzles are displaceable to adapt the distance of their mouths to bands of different widths according to the double arrows.

Gemäß Figur 4 sind mindestens die der Beschichtungsstation 10 nachgeordneten Rollenpaare wie etwa 6 und 7 in Figur 1 zur seitlichen Führung des Bandes 1 mit einer keilförmig profilierten Lauffläche versehen, so dass die dargestellten Rollen 6.1 und 6.2 das Band nur an den Kanten der Bandseitenflächen berühren. Die Rollen, z.B. die Rollen 6.1 und 6.2, können freilaufend ausgebildet sein oder auf den Wellen nicht dargestellter Antriebsmotore sitzen, die die Umfangsgeschwindigkeit der Rollen synchron und in Übereinstimmung mit der augenblicklichen oder der augenblicklich erforderlichen Bandlaufgeschwindigkeit halten.According to FIG. 4 At least the roller pairs downstream of the coating station 10, such as 6 and 7 in FIG FIG. 1 provided for lateral guidance of the belt 1 with a wedge-shaped profiled tread so that the illustrated rollers 6.1 and 6.2 touch the tape only at the edges of the belt side surfaces. The rollers, such as rollers 6.1 and 6.2, may be freewheeling or seated on the shafts of unillustrated drive motors which maintain the peripheral speed of the rollers synchronously and in accordance with the instantaneous or instantaneous tape travel speed.
