Description

Verfahren und Mittel zum Herstellen von einstückigen in sich geschlossenen Rahmen, insbesondere Fenster- und Türrahmen Die Erfindung betrifft ein Verfahren zum Herstellen von einstückigen, in sich geschlossenen Rahmen, insbesondere Fenster- und Türrahmen, mit einem glasfaserverstärkten Gießharzmantel und einer vorgeformten, mit einer gegen Lösungsmittel und die Aushärtungswärme beständigen Umhüllung versehenen Einlage geringen spezifischen Gewichts in einer aus einem Ober- und einem Unterteil bestehenden Form.Method and means for producing one-piece self-contained Frame, in particular window and door frames The invention relates to a method for the production of one-piece, self-contained frames, in particular window frames and door frame, with a glass fiber reinforced cast resin jacket and a preformed, provided with a coating that is resistant to solvents and the heat of hardening Inlay with a low specific weight consisting of an upper and a lower part existing form.

Viele der zur Herstellung von vorgeformten Einlagen, den sogenannten Kernen, geeigneten Werkstoffe von geringem spezifischem Gewicht, wie Holz, insbesondere Balsaholz, Schaumkunststoffe, gepreßter Hanf, Stroh od. dgl. haben die Eigenschaft, mehr oder minder große Mengen des bei der Herstellung des Rahmens in die Form einzubringenden flüssigen Gießharzes aufzusaugen. Hierdurch wird das Erzeug-- nis unnötig schwer; außerdem bedingt dies einen mehr oder minder hohen Verbrauch an Gießharz. Many of the for the production of preformed insoles, the so-called Cores, suitable materials of low specific weight, such as wood, in particular Balsa wood, foam plastics, pressed hemp, straw or the like have the property more or less large amounts of that to be introduced into the mold during the manufacture of the frame to absorb liquid casting resin. This makes the product unnecessarily heavy; in addition, this requires a more or less high consumption of casting resin.

Auch kann eine Reihe von sonst als Einlagewerkstoff geeigneten Materialien, z. B. auf Grund ihrer Lösungsempfindlichkeit dem Gießharz gegenüber, keine Anwendung finden. A number of materials otherwise suitable as insert material can also be used, z. B. due to their sensitivity to solution to the casting resin, no application Find.

Diese Nachteile sind bereits erkannt worden, und man hat daher derartige Einlagen mit einer gegen Lösungsmittel und die Aushärtungswärme unempfindlichen Umhüllung, z. B. einer Polyesterfolie, versehen bzw. die Oberfläche der Einlagen durch eine Kunstharzbindung beschichtet. These drawbacks have already been recognized and therefore existed Inserts with an insensitive to solvents and the curing heat Wrapping, e.g. B. a polyester film, or the surface of the deposits coated by a synthetic resin bond.

Diese bekannten Maßnahmen sind aber zeitraubend und sehr arbeitsaufwendig. Entweder muß jeder Einlagenteil für sich mit einer Umhüllung versehen werden, oder es muß eine Kunstharzbindung auf seiner Oberfläche durch Streichen oder Spritzen aufgetragen werden. Hierzu kommt dann noch eine Trockenzeit für das Abdeckmittel. However, these known measures are time-consuming and very labor-intensive. Either each insert part must be provided with a cover for itself, or there must be a resin bond on its surface by painting or spraying be applied. In addition, there is then a drying time for the covering agent.

Anschließend wird dann als gesonderter Arbeitsgang die so vorbereitete Einlage vor deren Einsatz in den Formunterteil mit der Glasfaserverstärkung versehen, oder die Forminnenwand wird mit der Glasfaserverstärkung ausgekleidet. The prepared in this way is then used as a separate operation Provide the insert with the glass fiber reinforcement before inserting it into the lower part of the mold, or the inner wall of the mold is lined with the glass fiber reinforcement.

Diesem Bekannten gegenüber besteht die Erfindung darin, daß die Glasfaserverstärkung auf der Oberfläche einer lösungsmittel- und wärmebeständigen Folie fest angeordnet und die vorgeformte Einlage vor dem Einbringen in die Form mit diesem Schichtaufbau in einem Arbeitsgang umhüllt wird. In relation to this acquaintance, the invention consists in that the glass fiber reinforcement firmly arranged on the surface of a solvent- and heat-resistant film and the preformed insert with this layer structure before being introduced into the mold is wrapped in one operation.

Ein weiteres Merkmal der Erfindung besteht darin, daß die lösungsmittel- und wärmebeständige Folie mit der auf ihrer Oberfläche fest angeordneten Glasfaserverstärkung als Schlauch ausgebildet ist. Another feature of the invention is that the solvent- and heat-resistant sheet with the glass fiber reinforcement fixed on its surface is designed as a hose.

Hierdurch wird der dem Einhüllen der Einlage dienende Arbeitsaufwand weiterhin erheblich vermindert, da es nunmehr möglich ist, die Oberfläche der Einlage durch einfaches Überstreifen eines derart ausgebildeten Schlauches gleichzeitig gegen die Einwirkung des Gießharzes zu versiegeln und mit der Glasfaserverstärkung zu versehen. Dabei paßt sich der Schlauch bei entsprechend dem Umfang der Einlage gewählter lichter Weite der Querschnittsform der Einlage gut an. This is the wrapping of the insert serving workload further reduced considerably, since it is now possible to reduce the surface area of the insert by simply slipping over a hose designed in this way at the same time To seal against the action of the casting resin and with the glass fiber reinforcement to provide. The hose adapts to the size of the insert selected clear width of the cross-sectional shape of the insert well.

In der Zeichnung ist ein Ausführungsbeispiel eines nach der Erfindung hergestellten Fensterprofils im Querschnitt dargestellt. In the drawing, an embodiment is one according to the invention produced window profile shown in cross section.

Die Einlage 1 ist mit der Folie 4 versehen, die auf ihrer Oberfläche die mit dem Gießharz getränkte Glasfaserverstärkung 2 trägt. Mit der strichpunktierten Linie 3 ist die Trennfuge zwischen den in der Zeichnung nicht besonders dargestellten Formteilen angedeutet. The insert 1 is provided with the film 4 on its surface the glass fiber reinforcement 2 impregnated with the casting resin carries. With the dash-dotted Line 3 is the parting line between the not particularly shown in the drawing Moldings indicated.

Die Folie 4 kann z. B. aus einem mit der Glasfaserverstärkung 2 versehenen Band bestehen, mit dem die Einlage 1 umwickelt wird. Auch kann die Folie 4 aus einem mit der Glasfaserverstärkung 2 versehenen Folienblatt bestehen, in das die Einlage 1 vor ihrem Einsatz in die Form eingeschlagen wird. Besonders vorteilhaft besteht die Folie 4 aus einem außen mit der Glasfaserverstärkung 2 versehenen vorfabrizierten Schlauch. The film 4 can, for. B. from a provided with the glass fiber reinforcement 2 There are tape with which the insert 1 is wrapped. The film 4 can also consist of a with the glass fiber reinforcement 2 provided film sheet exist in which the insert 1 is hammered into the mold before it is used. It is particularly advantageous the film 4 from a prefabricated one provided with the glass fiber reinforcement 2 on the outside Hose.
