Description

Die Erfindung bezieht sich auf eine Eckverbindermaschine mit mindestens einer Stanz-Prägeeinrichtung für eine Ecke eines aus auf Gehrung geschnittenen Hohlprofilen und in die Hohlprofile eingesetzten Eckverbinder gefertigten Rahmens eines Fensters, einer Tür, eines Fassadenfeldes o.dgl. mit einem mit einer Winkelnut zur Anlage an der Rahmenecke versehenen Taster und mit zwei antreibbaren Stanzstempeln (siehe z.B. DE-A-2 264 643).The invention relates to a corner connector machine with at least one Stamping / embossing device for a corner of a hollow profile cut from a miter and used in the hollow profiles corner connector manufactured frame Window, a door, a facade field or the like. with one with an angular groove for System on the frame corner button and with two drivable stamps (see e.g. DE-A-2 264 643).

Es ist eine Eckverbindermaschine dieser Art bekannt (DE-OS 2 001 608), bei der die mit den Stanzstempeln bzw. Stanzmessern ausgerüsteten Prägeaggregate ortsfest auf einem Maschinentisch angeordnet sind, der als Auflage der die Rahmenecke bildenden Hohlprofile dient. Durch zusätzliche Profilunterlagen können die Hohlprofile zu den Stanzmessern bzw. zu den Stanzstempeln in der Höhenlage ausgerichtet werden. Zur Einstellung der Rahmenecke auf das gewünschte Stanzmaß ist ein Taster vorgesehen, der mit einer Winkelnut zur Anlage an der Rahmenecke ausgerüstet ist und der in seiner Längsachse gegenüber dem Maschinentisch verstellbar ist. A corner connector machine of this type is known (DE-OS 2 001 608), in which the stationary with the punching dies or punching knives are arranged on a machine table, which acts as a support for the frame corner Serves hollow profiles. With additional profile underlay, the hollow profiles aligned with the punching knives or the punching dies at high altitude become. To set the frame corner to the desired punch size, use a Button provided, which is equipped with an angular groove for contact with the frame corner and which is adjustable in its longitudinal axis relative to the machine table.

Bei der bekannten Eckverbindermaschine sind für jedes die Rahmen bildenden Profilsystem spezielle Stanzmesser erforderlich, die in ihrer Länge variieren, da die Stanz- und Prägeaggregate einen fest vorgegebenen Hub aufweisen.In the known corner connector machine are the frame system for each profile system special punching knives are required, which vary in length as the Stamping and embossing units have a fixed predetermined stroke.

Für den Verarbeiter ist somit der Nachteil gegeben, daß für die verschiedenen Rahmenprofile eine Vielzahl unterschiedlicher Stanzmesser zur Verfügung stehen müssen. Hierbei sind Verwechslungen und daraus entstehende irreparable Schäden an Rahmen und Stanzmessern keine Seltenheit. Auch das Einrichten der Eckverbindermaschinen ist mit erheblichem Aufwand verbunden.The disadvantage for the processor is that for the different frame profiles a large number of different punching knives must be available. Here there are confusions and resulting irreparable damage Frames and punching knives are not uncommon. Also setting up the corner connector machines is associated with considerable effort.

Bei heute üblichen Mehrkammerprofilen, die durch die wärmegedämmten Verbundprofile vorgegeben sind, müssen Profile gestanzt werden, deren Kammern zur Aufnahme der Eckverbinder senkrecht zur Rahmenebene nicht mehr miteinander fluchten. Das heißt, daß die Einstanzpunkte - auf die Gehrungsebene gesehen - nicht mehr übereinstimmen, sondern einen Versatz aufweisen.With today's common multi-chamber profiles, thanks to the thermally insulated composite profiles profiles have to be punched, the chambers of which are to be received the corner connector is no longer aligned perpendicular to the frame level. This means that the punching points - seen at the miter level - are not match more, but have an offset.

Bei den bekannten Eckverbindermaschinen, die als Einkopf- oder Mehrkopfeckverbindermaschinen ausgerüstet sein können, ist es somit erforderlich, den Stanz- und Prägeaggregaten entsprechende mehrschneidige Stanzwerkzeuge zuzuordnen, die diesen vorgegebenen Kammerversatz ausgleichen. Dementsprechend ist es erforderlich, bei einem Rahmenprofilwechsel auch einen Wechsel der Stanzmesser und eine Neujustierung der Maschine vorzunehmen.In the known corner connector machines, which are used as single-head or multi-head corner connector machines can be equipped, it is therefore necessary to punch and To assign embossing units corresponding multi-edged punching tools compensate for this predetermined chamber offset. Accordingly, it is necessary with a frame profile change also a change of the punching knife and readjust the machine.

Der Erfindung liegt die Aufgabe zugrunde, eine Eckverbindermaschine der eingangs genannten Art so zu gestalten, daß eine Stanzstempel- bzw. Stanzmesserausführung ausreicht, um sämtliche Stanzprägungen an Rahmen vorzunehmen, die in verschiedenen Abmessungen und auch aus unterschiedlichen Rahmenprofilen gefertigt werden. Ferner soll das Einrichten auf ein anderes Rahmenprofil wesentlich vereinfacht werden.The invention has for its object a corner connector machine of the beginning mentioned type so that a punch or punch knife design is sufficient to make all die-cuts on frames that are in different Dimensions and also made from different frame profiles become. Furthermore, setting up on a different frame profile should be considerably simplified become.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des kennzeichnenden Teils des Patentanspruches 1 in Verbindung mit den Merkmalen des Oberbegriffs gelöst.This object is achieved by the subject matter of the characterizing Part of claim 1 in connection with the features of the preamble solved.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention emerge from the subclaims.

Der Eckverbinder 1, der eine geschlossene oder teiloffene Kammer eines auf Gehrung geschnittenen Rahmenprofils 2 eingesetzt wird, weist an jedem seiner Schenkel 3 an der Außen- oder Innenseite eine Nut oder eine entsprechend geformte Kalotte 4 auf. Mittels eines Stanzstempels 5, der der entsprechenden Nut oder Kalotte 4 maßlich zugeordnet ist, erfolgt ein Prägestanzen von Wandungsmaterial des Rahmenprofils 2. Der Stanzstempel 5 prägt einen Stanzbutzen 6 aus, der zur Gehrungsseite hin am Rahmenprofil 2 einstückig angelenkt bleibt.The corner connector 1, which is a closed or partially open chamber with a miter cut frame profile 2 is used, has on each of its legs 3 on the outside or inside a groove or a correspondingly shaped dome 4 on. By means of a punch 5, the corresponding groove or dome 4 dimensionally is assigned, stamping of wall material of the frame profile takes place 2. The punch 5 embossed a punching slug 6, the miter side remains articulated in one piece on the frame profile 2.

Der Stanzstempel 5 weist eine Wirkrichtung 7 auf, die zur Gehrungsebene 8 einen Winkel α bildet, der im allgemeinen ein spitzer Winkel ist.The punch 5 has a direction of action 7, the one to the miter plane 8 Forms angle α, which is generally an acute angle.

Zwischen der Wirkrichtung 7 des Stanzstempels 5 und der Wirkfläche 9 der Nut 4 des Eckwinkels 1 ergibt sich ein spitzer Winkel β, der dafür sorgt, daß der in die Nut 4 eingeprägte Stanzbutzen 6 sich an der Wirkfläche 9 abstützt und durch die Keilwirkung des Winkels β eine Reaktionskraft auf die Rahmenprofilgehrung ausübt, so daß sich ein unter Vorspannung stehender Formschluß der Gehrungsflächen ergibt. Die Eckverbindermaschine nach der Fig. 2 geht in ihrem konstruktiven Aufbau auf die DE-OS 2 001 608 zurück. Diese Eckverbindermaschine weist einen Stanzkopf auf mit jeweils zwei unter einem Winkel α zur Gehrungsachse angeordneten Stanzeinheiten, die mit Stanzstempeln 5 bzw. Stanzmessem ausgerüstet sind. Die Ausrichtung der auf Gehrung geschnittenen und mit dem Eckverbinder versehenen Rahmenecken erfolgt mittels eines winkelförmigen Tasters 11, der je nach Maßaufbau des Eckwinkels hinsichtlich seiner Nuten 4 in Gehrungsrichtung ausgerichtet werden muß. Mittels Spannzylinder werden dann die Rahmenprofile auf der Profilauflage 10 festgespannt, während von der Gehrungsinnenseite ein Widerlager 12 in die Rahmenecke hineingefahren wird, das die Aufgabe hat, bei Einkopfeckverbindermaschinen den Stanzdruck während des Fügevorganges aufzunehmen.Between the effective direction 7 of the punch 5 and the effective surface 9 of the groove 4 The corner angle 1 results in an acute angle β, which ensures that the in the groove 4 stamped slugs 6 are supported on the active surface 9 and by the wedge effect of the angle β exerts a reaction force on the frame profile miter so that there is a pre-stressed positive connection of the miter surfaces. The 2 goes in its structural design on the DE-OS 2 001 608 back. This corner connector machine has a punching head each with two punching units arranged at an angle α to the miter axis, which are equipped with punch 5 or punch knife. The alignment the mitred frame corners with the corner connector takes place by means of an angular button 11, which, depending on the size structure of the corner angle with respect to its grooves 4 are aligned in the miter direction got to. The frame profiles are then placed on the profile support 10 by means of a tensioning cylinder clamped, while from the inside of the miter an abutment 12 in the corner of the frame is driven in, which has the task of single-head corner connector machines to record the punching pressure during the joining process.

Dieses Widerlager kann bei Vierkopfeckverbindermaschinen entfallen, da bei einem gleichzeitigen Stanzvorgang mit allen vier Stanzköpfen sich die Stanzkräfte im Rahmen gegenseitig aufheben.This abutment can be omitted in four-headed corner connector machines, since one Punching process with all four punching heads at the same time, the punching forces in the frame cancel each other out.

Die Fig. 3 zeigt die maßlichen Abhängigkeiten, denen ein Profilsystem unterworfen ist. Bezogen auf den Eckverbinder 1 ist systemmäßig ein Einstanzpunkt 13 am Eckwinkel 1 festgelegt, der sich in bezug auf den 90°-Außenwinkel des Eckverbinders durch die Maß A und B oder C ergibt.3 shows the dimensional dependencies to which a profile system is subjected is. Relative to the corner connector 1 is a punch point 13 at the corner angle 1, which is related to the 90 ° outer angle of the corner connector by the dimensions A and B or C.

Dieser so definierte Einstanzpunkt 13 ist bei allen in einer Serie vorkommenden Eckwinkeln in der Regel grundsätzlich gleich. Daraus ergibt sich in die Gehrungsebene 8 projiziert ein Stanzmaß E bezogen auf die theoretische Außenecke des Eckwinkels 1.This punching point 13 defined in this way is for all corner angles occurring in a series generally the same. This results in miter level 8 projects a punch dimension E in relation to the theoretical outside corner of corner bracket 1.

Das Profileinstanzmaß R bezogen auf die Rahmenecke ist abhängig von der Profilwanddicke b und dem Spiel s zwischen dem Eckwinkel und der Profilkammer, in die der Eckwinkel eingesetzt ist.The profile punching dimension R in relation to the frame corner depends on the profile wall thickness b and the game s between the corner bracket and the profile chamber, in the the corner bracket is inserted.

Das in der Fig. 3 angegebene Maß x stellt die Summe b und s dar, so daß die Gleichung ergibt x = b + s. The dimension x shown in FIG. 3 represents the sum b and s, so that the equation results x = b + s.

Das Profileinstanzmaß beträgt R = E + X x 2. The profile punching dimension is R = E + X x Second

Die Fig. 4 zeigt einen Kopf 14 einer Eckverbindermaschine, dessen Auflage 10 einen aus Rahmenprofilen 2 bestehenden Profilrahmen trägt. Die Rahmenecke wird an einem ortsfesten Taster 15 ausgerichtet und z.B. durch entsprechende Spannzylinder und ggf. einem Widerlager, sofern es sich um eine Einkopfmaschine handelt, fixiert. Der auf der Auflage 10 angeordnete, ortsfeste Taster 15 liegt an der Wand der äußersten Eckverbinderkammer des in der Fig. 5 dargestellten wärmegedämmten Verbundprofils 16 an. Das Verbundprofil 16 ist mit Kammern 17 und 18 ausgerüstet, deren mit einer oder mehreren Sicken zu versehenen Wandungen 19,20 einen Versatz 21 aufweisen. Als äußere Kammer zur Aufnahme eines Eckwinkels ist die Kammer 17 anzusehen, so daß sich der Taster 15 gemäß Fig. 4 an der Gehrungsecke - gebildet aus der Wand 19 - anlegt und damit den Rahmen für die Eckenstanzung ausrichtet.Fig. 4 shows a head 14 of a corner connector machine, the support 10 one 2 existing frame frames from frame profiles. The frame corner turns on a stationary button 15 aligned and e.g. by means of appropriate clamping cylinders and, if necessary, an abutment, if it is a single-head machine. The arranged on the pad 10, fixed button 15 is on the wall of the outermost corner connector chamber of the thermally insulated shown in FIG Composite profile 16. The composite profile 16 is equipped with chambers 17 and 18, whose walls 19, 20 to be provided with one or more beads have an offset 21 have. As the outer chamber for receiving a corner angle is the View chamber 17 so that the button 15 as shown in FIG. 4 on the mitred corner - Formed from the wall 19 - creates and thus the frame for the corner punch aligns.

Der Taster 15, welcher auf der Auflage 10 höhenverstellbar ausgebildet ist, kann aber auch an jedem anderen Punkt der Rahmenecke, so z.B. auch am Anschlagsteg 22 im äußeren Bereich der Rahmenecke angeordnet werden.The button 15, which is height-adjustable on the support 10, can but also at every other point of the frame corner, e.g. also on the landing stage 22 can be arranged in the outer region of the frame corner.

Die Stanzstempel 5 werden über Antriebsaggregate 23 angetrieben, die elektro-, hydro- oder pneumomechanisch arbeiten. Diese Antriebsaggregate 23 führen den jeweiligen Stanzvorgang aus.The punch 5 are driven by drive units 23, the electro, work hydro- or pneumomechanically. These drive units 23 lead the each punching process.

Beide Antriebsaggregate 23 sind auf einem Führungsschlitten 24 montiert, der in seiner Mittellinie 8a, die in der Gehrungsebene 8 liegt, verstellbar und positionierbar ist.Both drive units 23 are mounted on a guide carriage 24 which in its Center line 8a, which lies in the miter plane 8, is adjustable and positionable.

Die Fig. 6 zeigt eine erfindungsgemäße Vierkopfeckverbindermaschine, die über vier gleiche Köpfe verfügt. Jeder Kopf bringt in eine Rahmenecke die Sicken zum Festlegen des oder der Eckverbinder ein. Aus Platzgründen in der Werkstatt und zum besseren Handhaben des aus Hohlprofilen erstellten Rahmens ist es vorteilhaft, die Köpfe der Maschine senkrecht über- und nebeneinander anzuordnen bzw. sie in einer leicht geneigten Rückenlage vorzusehen.6 shows a four-head corner connector machine according to the invention, which has four has the same minds. Each head brings the beads in a corner of the frame to fix of the corner connector (s). For space reasons in the workshop and for the better Handling the frame created from hollow profiles, it is advantageous to Arrange the machine heads vertically above and next to each other or in provide a slightly inclined supine position.

Die Maschine verfügt über eine Basis 25, die das Maschinengestell bildet und auf der senkrecht bzw. leicht nach schräg oben geneigt ein Führungsgestell angeordnet ist.The machine has a base 25 which forms the machine frame and on which a guide frame is arranged vertically or slightly inclined obliquely upwards.

Der linke untere Kopf 14.1 ist ortsfest montiert, während der darüber vorgesehene Kopf 14.2 senkrecht dazu verstellt und positioniert werden kann. Der rechte untere Kopf 14.4 ist zum Kopf 14.1 horizontal verstellbar und arretierbar. Der Kopf 14.3 kann sowohl eine horizontale als auch eine vertikale Bewegung ausführen, um seine Betriebsstellung einzunehmen bzw. aus der Betriebsstellung herauszufahren.The lower left head 14.1 is fixed in place, while the one provided above it Head 14.2 can be adjusted and positioned perpendicular to it. The lower right Head 14.4 is horizontally adjustable and lockable to head 14.1. The head 14.3 can perform both a horizontal and a vertical movement to its Take up the operating position or move out of the operating position.

Die vertikale Achse 27 und die horizontale Achse 28 können rechnergesteuert verfahren und positioniert werden. Hierbei werden die Köpfe 14 so vorpositioniert, daß das Maß zwischen den Tastern 15 geringfügig, d.h. ca. 3 mm größer ist als das Rahmenmaß an der entsprechenden Tasterposition am Rahmenprofil. Hiermit ist das Einlegen des Rahmens sichergestellt. Danach fährt jeder Kopf 14 in die endgültige Rahmenmaßposition. Hierauf werden die entsprechenden Stanzungen im Eckbereich durchgeführt.The vertical axis 27 and the horizontal axis 28 can move under computer control and be positioned. Here, the heads 14 are pre-positioned so that the dimension between the buttons 15 slightly, i.e. is about 3 mm larger than that Frame dimensions at the corresponding button position on the frame profile. This is it Inserting the frame ensured. Then each head 14 moves to the final one Rahmenmaßposition. Then the corresponding die cuts in the corner area carried out.

Wie aus der Fig. 5 zu entnehmen ist, werden nicht nur Einkammerprofile sondern auch Mehrkammerprofile zu Rahmenholmen verarbeitet. Diese Profile können eine Mehrfachstanzung sowohl innerhalb einer Kammer als auch in zwei getrennten Kammern erforderlich machen.As can be seen from FIG. 5, not only single-chamber profiles but Multi-chamber profiles also processed into frame bars. These profiles can be one Multiple punching both within one chamber and in two separate chambers make necessary.

Bei dem Verbundprofil 16 nach der Fig. 5 sind zumindest in den Bereichen 29 und 30 Einstanzungen vorzunehmen. Bei breiten Kammern, wie z.B. bei der Kammer 17, können auch anstelle einer Stanzung in dem Bereich 29 zwei Stanzungen in den Bereichen 31 und 31 vorgenommen werden. Darüber hinaus lassen sich auch Hohlprofile mit mehr als zwei Kammern als Rahmenholme verarbeiten.5 are at least in the areas 29 and 30 To make punchings. With wide chambers, e.g. at chamber 17, can instead of a punch in the area 29 two punchings in the Areas 31 and 31 are made. In addition, hollow profiles can also be used Process with more than two chambers as frame bars.

Dieses Stanzen bzw. Sicken in den Bereichen 29 bis 32 wird durch ein Takten bzw. Positionieren der Auflage 10 des jeweiligen Kopfes 14 ermöglicht. Hierbei bildet die Auflage 10 sowie der Taster 15 eine Baueinheit, in der der Taster 15 gegenüber der Auflage 10 höhenverstellbar ist. Die Stanzpositionen der verstellbaren Auflage 10 werden entweder durch fest vorgegebene Taktpositionen bestimmt oder vorgegeben und stufenlos elektronisch angesteuert.This punching or beading in the areas 29 to 32 is achieved by clocking or Positioning the pad 10 of the respective head 14 allows. Here forms the Edition 10 and the button 15 a unit in which the button 15 opposite the Edition 10 is adjustable in height. The punch positions of the adjustable pad 10 are either determined by predefined clock positions or predefined and continuously controlled electronically.

Wie bereits im Zusammenhang mit der Fig. 3 beschrieben, sind die Einstanzmaße der Eckwinkel eines Systems oder einer Serie an allen zur Anwendung kommenden Eckverbindern gleich. Das heißt, daß alle Einstanzpunkte innerhalb eines Profilsystems grundsätzlich rechts und links der Gehrungsebene 8 immer auf einer Parallelen liegen, die um das Maß B von dieser Ebene 8 entfernt sich erstreckt. Dies ergibt sich aus den Fig. 6 und 7.As already described in connection with FIG. 3, the punching dimensions are the corner angle of a system or a series on all used Corner connectors the same. That means that all punching points within a profile system always right and left of the miter level 8 always on a parallel lie, which extends by the dimension B from this level 8. This results in 6 and 7.

Während in der Fig. 3 das Einstellmaß der Stanzstempel 5 mittels des Führungsschlittens 24 noch auf die Kammerwandung bezogen ist, ist in der Fig. 7 das Einstellmaß R für die jeweilige Einstanzung auf das jeweilige Abstandsmaß X1 des Eckwinkels von der Tasterebene abhängig. Das sich ergebende jeweilige Einstanzmaß R1 errechnet sich dann aus der Summe des Eckverbindereinstanzmaßes E und dem Summanden X1 x 2 R1 = E + X1 x 2. While in FIG. 3 the setting dimension of the punch 5 is still related to the chamber wall by means of the guide carriage 24, in FIG. 7 the setting dimension R for the respective punching is dependent on the respective distance dimension X 1 of the corner angle from the key plane. The resulting stamping dimension R1 is then calculated from the sum of the corner connector stamping dimension E and the addend X 1 x 2 R1 = E + X 1 x 2 ,

Besonders deutlich ergibt sich dieser Zusammenhang aus der Fig. 8.This relationship emerges particularly clearly from FIG. 8.

Unter der Voraussetzung, daß die Tasterposition 33 sich an der äußersten Kammerwandung 19 befindet, ergibt sich zur nächsten mit einer Einstanzung zu versehenden Kammerwandung ein Profil- bzw. Wandungsversatz von V2. Unter der Voraussetzung einer gleichen Dicke der Wandungen 19 und 20 ergibt sich dann ein Zustellweg R2 des Führungsschlittens 24 von der ersten zur zweiten Stanzung von V2 x 2 R2 = V2 x 2. Provided that the button position 33 is located on the outermost chamber wall 19, there is a profile or wall offset of V 2 to the next chamber wall to be stamped. Assuming the walls 19 and 20 have the same thickness, there is an infeed path R 2 of the guide carriage 24 from the first to the second punching of V 2 x 2 R 2 = V 2 x Second

Aufgrund der Verstellbarkeit der Einstanzpunkte 13 entlang einer Parallelen zur Gehrungslinie, die in der Gehrungsebene 8 verläuft, und durch eine Bewegung der Auflage 10 der Rahmenecke senkrecht zu dieser Verstellinie in der Gehrungsebene wird ermöglicht, daß mittels eines einzelnen Stanzmessers pro Antriebsaggregat 23 sämtliche Stanzungen an einem Rahmen ausgeführt werden können.Due to the adjustability of the punching points 13 along a parallel to the miter line, which runs in the miter plane 8, and by moving the support 10 of the frame corner is perpendicular to this adjustment line in the miter plane enables all by means of a single punch knife per drive unit 23 Die cuts can be made on a frame.

In vorteilhafter Weise werden die Stanzmaße R in Abhängigkeit von der Tasterposition 33 elektronisch angesteuert und positioniert. Ferner wird die Höhenlage der Einzelstanzungen in den Bereichen 29 bis 32 durch eine entsprechende Einstellung der Auflage 10 zu den Stanzmessern elektronisch vorgenommen, so daß das Einrichten der Maschine auf ein neues Rahmenprofil auf ein Minimum reduziert wird.The punching dimensions R are advantageously dependent on the button position 33 electronically controlled and positioned. Furthermore, the height of the individual die cuts in the ranges 29 to 32 by an appropriate setting of the Edition 10 to the punching knives made electronically so that the setup the machine is reduced to a minimum on a new frame profile.

Auch die Einstellung der Höhe der Taster 15 gegenüber der Auflage 10 kann automatisch durch Takten bzw. durch eine gesteuerte Verstellung erfolgen.The adjustment of the height of the buttons 15 relative to the support 10 can also be done automatically by clocking or by a controlled adjustment.

Die Stanzstempel 5 sind mit ihren Antriebsaggregaten 23 auf einem Führungsschlitten 24 angeordnet, mit dem die Stanzstempel parallel zur Gehrungslinie verfahrbar sind, die in der Gehrungsebene 8 liegt. Die Antriebsaggregate 23 sind in Richtung der eigenen Wirkachse 7 stufenlos verstellbar. Bei elektronischer Positionierung dieser Wirkachse ist auch das Maß B variierbar. Die Voraussetzung des einheitlichen Maßes B bezüglich der Einstanzpunkte an Eckverbinder einer Serie ist damit nicht erforderlich.The punch 5 are with their drive units 23 on a guide carriage 24 arranged with which the punch can be moved parallel to the miter line are in miter plane 8. The drive units 23 are in the direction the own effective axis 7 continuously adjustable. With electronic positioning of this Dimension B can also be varied in the effective axis. The requirement of uniform Dimension B with regard to the punching points on corner connectors of a series is therefore not required.

Bei den in der Fig. 4 und in der Fig. 6 dargestellten Ausführungsbeispielen sind an der Auflage 10 Rollenauflager 34 für die Rahmenecke vorgesehen. Diese Rollenauflager 34 fluchten in den Ausführungsbeispielen mit den Tastflächen des Tasters 15. Die Rollenauflager 34 weisen ein federndes Widerlager auf. Durch diese Rollenauflager 34 wird das Gewicht des Rahmens abgetragen, so daß den Tastern 15 ausschließlich die Positionierung der Rahmenecke zukommt.In the embodiments shown in FIG. 4 and in FIG. 6 are on the support 10 roller supports 34 are provided for the frame corner. These roller bearings 34 are aligned in the exemplary embodiments with the touch surfaces of the button 15. The roller supports 34 have a resilient abutment. Through these roller supports 34 the weight of the frame is removed, so that the buttons 15 exclusively the positioning of the frame corner is important.

Die Rahmenecken sind jeweils an einer Seite mit einer Klebereinspritzbohrung 35 versehen. Für jede Profilkammer, die einen Eckverbinder aufnimmt, ist eine derartige Klebereinspritzbohrung vorgesehen.The frame corners are each on one side with an adhesive injection hole 35 Mistake. For each profile chamber that receives a corner connector, there is one Glue injection hole provided.

Eine mit einer Düsenspitze 36 ausgerüstete Klebereinspritzvorrichtung 37 ist am Führungsschlitten 24 befestigt. Diese Düsenspitze führt lediglich einen Hin- und Rückhub in bezug auf die Klebereinspritzbohrung 35 aus. An adhesive injection device 37 equipped with a nozzle tip 36 is on the guide carriage 24 attached. This nozzle tip only carries out a return stroke with respect to the adhesive injection bore 35.

Die Klebereinspritzbohrung ist, wie der Einstanzpunkt 13 auf einer Parallelen zur Gehrungslinie angeordnet, so daß die Positionierung der Klebereinspritzvorrichtung 37 in gleicher Weise erfolgt wie die Positionierung der Stanzstempel 5. The adhesive injection hole, like the punching point 13, is on a parallel to Miter line arranged so that the positioning of the glue injector 37 is carried out in the same way as the positioning of the punch 5.
