Der vorliegenden Erfindung liegt die Aufgabe zugrunde, überziehbare Schnallen mit zueinander nicht parallel verlaufenden Ober- und Unterflächen zu schaffen, die maschinell herstellbar sind sowie eine Vorrichtung hierfür.The present invention has for its object to provide pull-on buckles with non-parallel top and bottom surfaces that can be produced by machine and a device therefor.

Erfindungsgemäß wird dies für eine Schnalle der eingangs beschriebenen Art dadurch erreicht, daß ihre Unterfläche und ihre Oberfläche nicht parallel zueinander verlaufen, wobei die die Unterfläche bildende Unterseite des Schnallenunterteils parallel zur Öffnungsebene der Unterseite des Schnallenoberteils und die Öffnungsebene der Oberseite des Schnallenunterteils parallel zur die Oberfläche bildenden Oberseite des Schnallenoberteils verlaufen.According to the invention, this is achieved for a buckle of the type described in the introduction in that its lower surface and its surface do not run parallel to one another, the lower surface of the lower part of the buckle forming the lower surface parallel to the opening plane of the lower side of the upper buckle part and the opening plane of the upper side of the lower buckle part parallel to the surface forming top of the buckle top.

Aufgrund dieser erfindungsgemäßen Ausführungsform kann erfindungsgemäß eine Vorrichtung der eingangs beschriebenen Art zur Herstellung verwendet werden, bei der im Unterwerkzeug zur Aufnahme des Schnallenunterteils eine senkrecht zur Werkzeugschließ- und Trennbewegungsachse verlaufende Bezugsebene gebildet ist und im Oberwerkzeug für das Schnallenoberteil eine Aufnahme mit einer schräg zur Achse verlaufenden Auflagefläche, sowie Trenn- und Formflächen in den Werkzeugen ausgebildet sind, die mit derselben Neigung zur Bezugsebene verlaufen wie die Oberfläche des Schnallenoberteils zu dessen Unterseite. Alternativ kann im Unterwerkzeug zur Aufnahme des Schnallenunterteils eine mit derselben Neigung wie die Oberfläche des Schnallenoberteils zu dessen Unterseite schräg zur Werkzeugschließ- und Trennbewegungsachse verlaufende Bezugsebene ausgebildet sein und im Oberwerkzeug für das Schnallenoberteil eine Aufnahme mit einer senkrecht oder schräg zur Achse verlaufende Auflagefläche sowie in den Werkzeugen Trenn- und Formflächen, die senkrecht zur Achse verlaufen.Due to this embodiment of the invention, a device of the type described in the introduction can be used according to the invention, in which a reference plane perpendicular to the tool closing and separating movement axis is formed in the lower tool for receiving the buckle lower part and in the upper tool for the buckle upper part a receptacle with an inclined axis Support surface, as well as parting and shaping surfaces are formed in the tools, which run with the same inclination to the reference plane as the surface of the buckle upper part to its underside. Alternatively, a reference plane with the same inclination as the surface of the upper part of the buckle to the underside of the upper part of the buckle can be formed in the lower tool for receiving the lower part of the buckle, and in the upper tool for the upper part of the buckle a receptacle with a support surface running perpendicularly or at an angle to the axis, as well as in the Tools parting and forming surfaces that run perpendicular to the axis.

Aufgrund der Erfindung wird trotz der bestehenden Unsymmetrie in der Form der Schnalle eine eindeutige senkrecht zur Werkzeugschließ- und -trennachse verlaufene Bezugsfläche geschaffen, die eine eindeutige Zuordnung der Werkzeugteile zueinander zuläßt.Due to the invention, in spite of the existing asymmetry in the shape of the buckle, a clear reference surface is created which runs perpendicular to the tool closing and separating axis and which allows the tool parts to be clearly assigned to one another.

Die Aufnahmekontur ist derart konkav profiliert, daß eine Aufnahme für das stoffüberzogene Oberteil 1 besteht. Die Formfläche 31 der Aufnahme 30 verläuft schräg zur Achse X-X und parallel oder schräg zu den Trennflächen 21, 25.On its underside facing the lower tool 12, the upper tool 11 has on its upper part 13 a circumferential extension 20 with an end parting surface 21. A core piece 23 is mounted within the through opening 14 of the upper part 13 and is movably connected to the upper part 13. The separating surface 25 of the core piece 23 facing the lower tool 12 extends obliquely to the tool separating and firing axis X-X. The separating surfaces 21 of the extensions 20 are designed accordingly, so that the separating surfaces 21 form a continuation of the surface 25. The core piece 23 is fastened in the upper part 13 such that a circumferential gap 26 is formed between the core piece 23 and the upper part 13. The upper tool 11 also has an outer core piece, which consists of a head plate, not shown, and a circumferential wall 29, which comprises a cavity. The wall 29 is adapted with regard to the thickness and course of the width and the contour of the gap 26, so that the gap 26 is closed at the top by the wall 29 and forms a circumferential receptacle 30. The receiving contour is profiled in a concave manner so that there is a receptacle for the fabric-covered upper part 1. The shaped surface 31 of the receptacle 30 runs obliquely to the axis X-X and parallel or obliquely to the separating surfaces 21, 25.

Die Einzelteile des Oberwerkzeuges 11 sind derart angeordnet, daß einerseits das Oberteil 13, das Kernstück 23 und das Außenkernstück gemeinsam in Richtung auf das Unterwerkzeug 12 bewegt werden können, und andererseits derart, daß das Außenkernstück zu dem miteinander verbundenen Oberteil und Kernstück relativ verschoben werden kann.The individual parts of the upper tool 11 are arranged such that on the one hand the upper part 13, the core piece 23 and the outer core piece can be moved together in the direction of the lower tool 12, and on the other hand such that the outer core piece is connected to the connected upper part and core can be moved relatively.

Das Unterwerkzeug 12 besteht aus einem Unterteil 35 mit einer mittigen Durchgangsöffnung 36, die in ihrer Form der Außenkontur des Schnallenoberteiles 1 angepaßt ist und somit in ihrer Form der Durchgangsöffnung 14 im Oberwerkzeug 11 entspricht. In der dem Oberwerkzeug 11 zugekehrten Seite des Unterteiles 35 ist eine Aufnahme aus einem umlaufenden Absatz 37 ausgebildet, dessen Kontur dem Negativprofil des Fortsatzes 20 entspricht und eine Trennfläche 38 besitzt. Der durch den Absatz 37 gebildete Raum dient zur Aufnahme des Stoffzuschnittes 3 und ist insofern der Form dieses Zuschnitts angepaßt. Innerhalb der Durchgangsöffnung 36 kann ein nicht dargestellter Faltenhalter gelagert sein. Innerhalb der Durchgangsöffnung 36 ist ein Stoffeindrücker geführt, der aus einer Bodenplatte 43 mit einem nach innen versetzt angeordneten Kragen 44 besteht, wobei die Kragenwandung einen Verlauf besitzt, der der Form der Durchgangsöffnung 36 entspricht. Die stirnseitigen Formflächen 45 des Kragens verlaufen mit derselben Neigung zur Achse X-X wie die Flächen 38 der Absätze 37. An der Außenseite des Kragens 44 ist im Sinne einer Durchmesserverringerung ein umlaufender Absatz 46 ausgebildet. Dabei ist die Breite des Absatzes der Dicke des Randes des Schnallenoberteiles angepaßt. Die Breite der Formflächen 45 entspricht etwa der Breite des Schnallenoberteiles zwischen den beiden Rändern des Oberteiles, d. h. zwischen dem Außen- und dem Innenrand des Schnallenoberteils. Das Unterteil 35 ist gegenüber dem Stoffeindrücker 41 federnd gelagert, wobei die federnde Lagerung mittels Schraubenfedern 47 erfolgt, die sich auf der Bodenplatte 43 abstützen. An der Außenseite der Bodenplatte 43 ist ein Zapfen 48 angeordnet, der zur Befestigung des Unterteilwerkzeuges 12 in der Presse zur Aufnahme des Oberwerkzeuges 11 dient.The lower tool 12 consists of a lower part 35 with a central through opening 36, the shape of which is adapted to the outer contour of the buckle upper part 1 and thus corresponds in shape to the through opening 14 in the upper tool 11. In the side of the lower part 35 facing the upper tool 11, a receptacle is formed from a circumferential shoulder 37, the contour of which corresponds to the negative profile of the extension 20 and has a separating surface 38. The space formed by paragraph 37 is used to hold the fabric blank 3 and is therefore adapted to the shape of this blank. A fold holder (not shown) can be mounted within the through opening 36. A material presser is guided within the passage opening 36 and consists of a base plate 43 with a collar 44 which is offset inwards, the collar wall having a course which corresponds to the shape of the passage opening 36. The end face surfaces 45 of the collar run with the same inclination to the axis XX as the surfaces 38 of the shoulders 37. A circumferential shoulder 46 is formed on the outside of the collar 44 in the sense of a reduction in diameter. The width of the heel is adapted to the thickness of the edge of the buckle upper part. The width of the shaped surfaces 45 corresponds approximately to the width of the buckle upper part between the two edges of the upper part, ie between the outer and the inner edge of the buckle upper part. The lower part 35 is resiliently mounted with respect to the fabric pusher 41, the resilient mounting being carried out by means of helical springs 47 which are supported on the base plate 43. On the outside of the base plate 43, a pin 48 is arranged, which is used to fasten the lower tool 12 in the press for receiving the upper tool 11.

Der Arbeitsvorgang mit der in Fig. 3 dargestellten erfindungsgemäßen Vorrichtung ist nun wie folgt und ergibt sich aus den Fig. 3 und 4.The operation with the device according to the invention shown in FIG. 3 is now as follows and results from FIGS. 3 and 4.

Das Schnallenoberteil 1 wird mit dem darübergelegten Stoffzuschnitt 3 in das Unterteil 35 im Bereich des Absatzes 37 auf die Trennfläche 38 eingelegt. Das gesamte Oberwerkzeug 11 wird auf das Unterwerkzeug 12 herunterbewegt. Beim Herunterdrücken des Oberwerkzeuges 11 auf das Unterwerkzeug 12 drückt das Oberteil 13 das Unterteil 35 mit dem Kernstück 23 nach unten, wodurch das auf die Flächen 45 aufgelegte Schnallenoberteil 1 mit dem Stoffzuschnitt 3 nach oben gegen die Flächen in der Aufnahme 30 gedrückt wird, wo es derart positioniert wird, daß seine Unterseite 7 senkrecht zur Achse X-X verläuft. Hierbei ist es von Wichtigkeit, daß in der in Fig. 3 dargestellten Anordnung der Flächen 21, 25, 31 des Oberwerkzeuges 11 sowie der Flächen 38, 45 des Unterwerkzeuges mit der Neigung zur Achse X-X verlaufen, die der Konizität der fertigen Schnalle entspricht. Bei einem gewölbten Verlauf der Oberseite des Schnallenoberteils findet sich die entsprechende Kontur in den Flächen 21, 25, 31, 38, 45, so daß das eingepreßte Schnallenoberteil eine senkrecht zur Achse X-X verlaufende Unterseite aufweist.The buckle upper part 1 is placed with the fabric blank 3 placed over it in the lower part 35 in the area of the shoulder 37 on the separating surface 38. The entire upper tool 11 is moved down to the lower tool 12. When the upper tool 11 is pressed down on the lower tool 12, the upper part 13 presses the lower part 35 with the core piece 23 down, as a result of which the buckle upper part 1 placed on the surfaces 45 with the fabric blank 3 is pressed up against the surfaces in the receptacle 30, where it is is positioned so that its bottom 7 is perpendicular to the axis XX. It is important that in the arrangement of the surfaces 21, 25, 31 of the upper tool 11 and the surfaces 38, 45 of the lower tool shown in Fig. 3 with the inclination to the axis X-X, which corresponds to the taper of the finished buckle. If the upper side of the upper part of the buckle is curved, the corresponding contour is found in the surfaces 21, 25, 31, 38, 45, so that the pressed-in upper part of the buckle has an underside running perpendicular to the axis X-X.

In Fig. 4 ist die Endlage des Oberwerkzeuges 11 auf dem Unterwerkzeug 12 nach erfolgtem Herunterdrücken des Oberwerkzeuges dargestellt. In diese Endlage ragt der Kragen 44 in den Aufnahmeraum 30 hinein und hat das Schnallenoberteil 1 mit dem darüberliegenden Stoffzuschnitt 3 in die Aufnahme 30 hineingedrückt. Aus Fig. 4 ergibt sich dabei die Lage des Stoffzuschnitts 3 innerhalb des Aufnahmeraumes 30. Dabei wird das Schnallenoberteil 1 zusammen mit dem Stoffzuschnitt 3 derart innerhalb in dem Oberwerkzeug 11 gehalten, daß ein leichter Klemmsitz gegeben ist, so daß das Oberteil nicht herausfallen kann. Nachdem das Schnallenober teil 1 derart in das Oberwerkzeug 11 zusammen mit dem Stoffzuschnitt 3 hineingedrückt worden ist, wobei die Seitenränder des Stoffzuschnittes beidseitig nach unten hängen, kann das Unterwerkzeug 12 durch Hochziehen des Oberwerkzeuges außer Eingriff gebracht werden.4 shows the end position of the upper tool 11 on the lower tool 12 after the upper tool has been pressed down. In this end position, the collar 44 protrudes into the receiving space 30 and has pressed the upper buckle part 1 with the fabric cut 3 above it into the receptacle 30. 4 shows the position of the fabric blank 3 within the receiving space 30. The buckle upper part 1 together with the fabric blank 3 is held within the upper tool 11 in such a way that there is a slight clamping fit so that the upper part cannot fall out. After the buckle upper Part 1 has been pressed into the upper tool 11 together with the fabric blank 3, with the side edges of the fabric blank hanging down on both sides, the lower tool 12 can be disengaged by pulling up the upper tool.

Die Verbindung des Schnallenoberteils mit dem Unterteil erfolgt nun in bekannter Weise, wie es z. B. aus der DE-PS 977 665 bekannt ist. Hierzu wird das vorstehend beschriebene erste Unterwerkzeug 12 gegen ein zweites Unterwerkzeug 52, siehe Fig. 5, ausgetauscht. Dieses zweite Unterwerkzeug 52 besteht aus einem Unterteil 53, das als Fassungsrahmen ausgebildet ist. Dieses Unterteil ist gegen eine Grundplatte 54 eines Außenkernstückes mittels Federn 55 abgestützt. In einer der Form des Schnallenunterteils 2 entsprechenden Ausnehmung 63 ist ein als Gegenhalter wirkender Innenkern 56 federnd gelagert, und zwar mittels sich auf der Grundplatte 54 abstützender Schraubenfedern 57. Das Innenkernstück 56 hat eine stirnseitige Trennfläche 60. In den Spalt 58 ragt ein an der Grundplatte 54 befestigter Kragen 59 hinein und verschließt diese nach unten. Auf der stirnseitigen Formfläche 62 des Kragens 59 ist innerhalb des Spaltes 58 das Schnallenunterteil 2 aufgelegt. Das Unterteil 53 weist eine gegenüber der Ausnehmung 45 radial vergbrößerte Ausnehmung 66 auf, die zur Aufnahme des umlaufenden Fortsatzes 20 des Oberwerkzeuges 1 dient und dessen Negativprofil aufweist. Die Trennfläche 60 hat einen Verlauf, der dem Verlauf der übrigen Trennflächen 38, 45 angepaßt ist. Die Formfläche 62 bildet die Bezugsebene (7-7) des werkzeuges und sie verläuft rechtwinklig zur Achse X-X. Als weitere Bezugsebene (7˝-7′) kann der durch die Unterkante der von den Schließschrägen 64 gebildete Falz dienen, die ebenfalls senkrecht zur Achse X-X verläuft.The connection of the buckle upper part to the lower part is now carried out in a known manner, as z. B. is known from DE-PS 977 665. For this purpose, the first lower tool 12 described above is exchanged for a second lower tool 52, see FIG. 5. This second lower tool 52 consists of a lower part 53 which is designed as a frame. This lower part is supported against a base plate 54 of an outer core piece by means of springs 55. In a recess 63 corresponding to the shape of the lower part 2 of the buckle, an inner core 56 acting as a counter-holder is resiliently mounted, namely by means of helical springs 57 which are supported on the base plate 54. The inner core piece 56 has an end-side separating surface 60. A gap 58 projects into the base plate 54 attached collar 59 and closes it down. The lower part 2 of the buckle is placed on the end face surface 62 of the collar 59 within the gap 58. The lower part 53 has a recess 66 which is enlarged radially relative to the recess 45 and which serves to receive the peripheral extension 20 of the upper tool 1 and has its negative profile. The separating surface 60 has a course which is adapted to the course of the other separating surfaces 38, 45. The shaped surface 62 forms the reference plane (7-7) of the tool and it runs at right angles to the axis XX. As a further reference plane (7˝-7 ') can serve by the lower edge of the fold formed by the bevels 64, which also extends perpendicular to the axis XX.

Wird nun das erfindungsgemäße Werkzeug geschlossen, wie in Fig. 6 dargestellt ist, wobei das Oberwerkzeug 11 durch ein Druckorgan abwärts bewegt wird, so werden die noch offenen Ränder des Stoffzuschnittes 3 durch die im Unterwerkzeug 52 befindlichen Schließschrägen 64, 65 einwärts umgerollt. Erfindungsgemäß bilden die Schließschrägen 64 eine Außenfalz, wobei der Falzgrund jeweils in einer zur Achse X-X senkrechten Ebene liegt, wodurch die Bezugsebene des Werkzeuges gebildet wird. Bei weiterem Druck auf das Oberwerkzeug weicht nun das Unterteil 53 zurück und das Schnallenunterteil 2 wird in die Schließstellung, siehe Fig. 6, gebracht. Nunmehr erfolgt durch vollständiges Zusammenpressen von Ober- und Unterwerkzeug das Einstauchen der Schnallenober- und -unterteile und damit das Fixieren des Stoffzuschnittes. Beim vollständigen Zusammenpressen der beiden Werkzeuge weichen das Oberteil und das Innenkernstück des Oberwerkzeuges sowie das Unterteil und das Innenkernstück des Unterwerkzeuges zurück, so daß zwischen den Stirnflächen des Außenkernstückes 29 und des Kragens 59 Schnallenober- und -unterteil miteinander verpreßt werden.If the tool according to the invention is now closed, as shown in FIG. 6, the upper tool 11 being moved downwards by a pressure element, the still open edges of the fabric blank 3 are rolled inwards by the closing bevels 64, 65 located in the lower tool 52. According to the invention, the closing bevels 64 form an outer fold, the fold base lying in each case in a plane perpendicular to the axis X-X, as a result of which the reference plane of the tool is formed. With further pressure on the upper tool, the lower part 53 now withdraws and the buckle lower part 2 is brought into the closed position, see FIG. 6. Now the upper and lower parts of the buckle are immersed by completely pressing the upper and lower tools together and thus fixing the fabric blank. When the two tools are completely pressed together, the upper part and the inner core piece of the upper tool and the lower part and the inner core piece of the lower tool withdraw, so that 59 upper and lower parts of the buckle are pressed together between the end faces of the outer core piece 29 and the collar.

Hierbei gewährleistet der Verlauf des Falzes der Schließschrägen 64, daß die Unterseite 7 mit ihrem Rand im ungepreßten Zustand senkrecht zur Achse X-X verläuft.Here, the course of the fold of the closing bevels 64 ensures that the bottom 7 of the underside 7 extends perpendicular to the axis X-X in the unpressed state.

Die vorliegende Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, sondern umfaßt alle im Sinne der Erfindung gleich wirkenden Mittel. So ist es erfindungsgemäß ebenfalls möglich, wenn die Stirnflächen 62 und die durch den Falzgrund der Schließschrägen 64 verlaufende Ebene geneigt zur Achse X-X entsprechend der Neigung der nichtparallelen Ober- und Unterfläche (4,5) der Schnalle zueinander verlaufen und die Flächen 21, 25, 31 im Oberwerkzeug 11 und die entsprechenden Flächen 38, 45, 60 in den Unterwerkzeugen senkrecht zur Achse X-X.The present invention is not limited to the exemplary embodiment shown, but includes all means having the same effect in the sense of the invention. Thus, it is also possible according to the invention if the end faces 62 and the plane running through the rebate base of the locking bevels 64 are inclined to the axis XX in accordance with the inclination of the non-parallel top and bottom surfaces (4, 5) of the buckle and the surfaces 21, 25, 31 in the upper tool 11 and the corresponding surfaces 38, 45, 60 in the lower tools perpendicular to the axis XX.
