    Zum Abwinkeln einer Hohlprofilleiste 2 wird durch Betätigen des Druckmittelzylinders 13 zunächst die Biegewange 7 an die (nach unten weisende) Außenseite der Hohlprofilleiste 2 angelegt und nimmt diese, wie in Fig. 4 gezeigt, bevorzugt in einer entsprechend der Außenseite der Hohlprofilleiste 2 konturierten Fläche auf, so daß die Außenseite der Hohlprofilleiste 2 beim Biegevorgang gut abgestützt ist. Dann wird das Biegewiderlager 5 aus der in Fig. 1 in vollen Linien eingezeichneten Stellung in die in Fig. 1 punktiert eingezeichnete Stellung verschwenkt (Pfeil 24), wobei die Innenwand der Hohlprofilleiste 2 durch den Kopf 16 des Biegewiderlagers 5 bereichsweise nach innen verformt werden kann. Das Biegewiderlager 5 kann einschließlich seines Kopfes 16 eine Breite haben, die so bemessen ist, daß das Biegewiderlager 5 zwischen den über die Innenwand überstehenden Seitenwänden der Hohlprofilleiste 2 aufgenommen ist und die Seitenwände im Biegebereich, insbesondere während des eigentlichen Biegevorganges abstützt (vgl. Fig. 4).For bending a hollow profile strip 2 is by pressing the Pressure medium cylinder 13, first the bending cheek 7 to the (down pointing) outside of the hollow profile strip 2 is applied and takes these, as shown in Fig. 4, preferably in a corresponding to the Outside of the hollow profile strip 2 contoured surface, so that the outside of the hollow profile strip 2 well supported during the bending process is. Then, the bending stocker 5 from the in Fig. 1 in full lines drawn position in the dotted in Fig. 1 drawn position pivoted (arrow 24), the inner wall the hollow profile strip 2 through the head 16 of the bending stock 5 can be deformed in areas to the inside. The Biegewiderlager 5, including its head 16, can have a width that is so is dimensioned that the bending abutment 5 between the over the inner wall received on projecting side walls of the hollow profile strip 2 is and the side walls in the bending area, in particular during the actual bending process is supported (see Fig .. 4).

    Wenn die Hohlprofilleiste 2 so zwischen Biegewange 7 einerseits und Biegewiderlager 5 anderseits angeordnet ist, wird der Schwenkhebel 8 und damit die Biegewange 7 und synchron dazu das Biegewiderlager 5 um die Achse 6 verschwenkt, bis das über die Biegestelle (symbolisiert durch Pfeil 20 in Fig. 1) überstehende Ende der Hohlprofilleiste 2 mit dem anderen Teil der Hohlprofilleiste 2 den gewünschten Winkel einschließt. Dieser Winkel kann beliebig groß sein und beispielsweise 90° betragen oder ein stumpfer oder ein spitzer Winkel sein, wie dies in den Fig. 2 und 3 gezeigt ist.If the hollow profile strip 2 so between bending beam 7 on the one hand and Biegewiderlager 5 is arranged on the other hand, the pivot lever 8 and thus the bending cheek 7 and in sync with the bending abutment 5 pivoted about the axis 6, until the over the bending point (symbolizes by arrow 20 in Fig. 1) projecting end of the hollow profile strip 2 with the other part of the hollow profile strip 2 the desired Includes angle. This angle can be arbitrarily large and, for example 90 ° or a dull or acute angle be as shown in Figs. 2 and 3.

    Nachdem der Biegevorgang beendet ist, wird der Schwenkhebel 8 mit der Biegewange 7 und das Biegewiderlager 5 in die in Fig. 1 gezeigte Stellung zurückgeschwenkt. Hierauf wird die Hohlprofilleiste 2 soweit vorgeschoben, bis die nächste Stelle in der eine Ecke durch Abwinkeln der Hohlprofilleiste 2 zu erzeugen ist, in der Biegestelle (Pfeil 20) ausgerichtet ist.After the bending process is completed, the pivot lever 8 is with the bending cheek 7 and the bending stock 5 in the in Fig. 1 shown Position swung back. Then the hollow profile strip 2 advanced so far, until the next point in a corner through Angling the hollow profile strip 2 is to produce, in the bending point (Arrow 20) is aligned.

    Die in Fig. 4 gezeigten Backen 14 und 15, zwischen welchen die Seitenwände der Hohlprofilleiste 2 gehalten und geführt sind, sind in Fig. 5 und 6 in mehr Einzelheiten gezeigt. Eine der beiden Backen (im gezeigten Ausführungsbeispiel die Backe 14) ist verstellbar, um den Biegekopf 1 unterschiedlich breite Hohlprofilleisten 2 anpassen zu können und um zwischen den einzelnen Biegevorgängen die Backen 14, 15 voneinander entfernen zu können, damit das Vorschieben der Hohlprofilleiste 2 vereinfacht wird.The jaws 14 and 15 shown in Fig. 4, between which the Side walls of the hollow profile strip 2 are held and guided, are in Figs. 5 and 6 shown in more detail. One of the two cheeks (In the embodiment shown, the jaw 14) is adjustable to adjust the bending head 1 different width hollow profile strips 2 to be able to and between the individual bending operations the baking 14, 15 can be removed from each other, so that the advancing the Hollow profile strip 2 is simplified.

    In den Fig. 5 und 6 ist das Biegewiderlager 5 in seiner Wirklage (in Fig 1 strichliert eingezeichnet) gezeigt. Zum Verschwenken des Biegewiderlagers 5 z.B. zum Verschwenken in die Stellungen der Fig. 2, 3, 7 oder 8 ist ein Drehmotor 20 vorgesehen, der einen Schwenkhebel 21 antreibt, der über einen Kupplungsarm 22 mit einem um die Achse 6 verschwenkbaren Hebel 23 angreift, so daß das Biegewiderlager 5 mit dem nach Art eines Parallelogrammtriebes ausgebildeten Antrieb im Sinne des Doppelpfeiles 24 in Fig. 1 verschwenkt werden kann.In FIGS. 5 and 6, the flexural deflector 5 is in its operative position (in FIG 1 dashed line drawn) shown.
