Verfahren zur Herstellung von mit Metalleinlagen versehenen KunststoffprofilenProcess for the production of metal inserts Plastic profiles
Es ist schon vorgeschlagen worden, Kunststoffprofile aus geschäumtem Polypropylen herausteilen. Diese Profile haben jedoch, da sie aus thermoplastischen Kunststoffen bestehen, den Nachteil, sich unter dem Hinfluß von Wärme zu deformieren. Dadurch wird ihre Verwendungsmöglichkeit erheblich eingeschränkt, da beispielsweise die Anwendungsraöglichkeit von aus diesen Profilen hergestellten Flechtwerken begrenzt 1st. Die Erfindung hat es sich nun zur Aufgabe gestellt, Kunststoffproflie, insbesondere solche aus geschäumtem Polypropylen, herzustellen, bei denen der oben geschilderte Nachteil nicht auftritt.It has already been proposed to make plastic profiles cut out foamed polypropylene. These profiles however, since they are made of thermoplastics, they have the disadvantage of being exposed to the influx of heat to deform. This makes their range of uses significant limited, for example because of the possibility of application limited by wickerwork made from these profiles. The invention has now turned to Task set, plastic profile, especially those made of foamed polypropylene, in which the disadvantage described above does not occur.

unwirtschaftlich, da bei der Umspritzung von Metalldrähten mit geschäumten Kunststoffen unter Verwendung von "Extrudern mit Querspritzköpfen eine max. Produktfonsgeschwindigkeit von etwa 3o m pro Minute erreicht wird. Da es im allgemeinen nur möglich ist einen Extruder mit einem Querspritzkopf auszurüsten, wird nach dem oben geschilderten Verfahren pro Extrudereinheit nur ein äusserst geringer Produktionsausstoß von in Scbaumkunststoffen eingebetteten Drahtprofilen in der Zeiteinheit erreicht.uneconomical, since metal wires are overmolded with foamed plastics using "Extruders with crossheads have a maximum product speed of about 30 m per minute is achieved. Since it is generally only possible to use an extruder Equipping a transverse injection head is extremely important according to the method described above per extruder unit low production output of those embedded in structural plastics Wire profiles reached in the unit of time.
Die Erfindung schlägt nun ein Verfahren zur Herstellung von mit Metalleinlagen versehenen Kunststoffprofilen vor, bei dem die oben geschilderten Nachteile vermieden werden. Es ist dadurch gekennzeichnet, daß eine von einer Vorrats^ rolle oder dergleichen ablaufende Metalleinlage zwischen mindestens zwei aus dem Extruder austretenden Kunststoff« profilen eingebettet wird, die anschließend miteinander verschweißt werden. Auf diese Weise lassen sich auch geschäumte Kunststoffprofile, insbesondere solche aus Polypropylen, mit einer Metalleinlage versehen, die die Eigen-'-" ,schäften dieser Kunststoffprofile erheblich verbessert. Als Metalleinlagen können dabei sowohl Bänder als auch Drähte oder beliebig geformte Profile verwendet werden.The invention now proposes a method for producing plastic profiles provided with metal inserts, in which the above-described disadvantages are avoided. It is characterized in that a metal insert running off a supply roll or the like is embedded between at least two plastic profiles emerging from the extruder, which are then welded to one another. In this way, foamed plastic profiles can, especially those made of polypropylene, fitted with a metal insert the self -'- "transactions of plastic profiles significantly improved. May be both bands and wires or arbitrarily shaped profiles as metal inserts are used.
Das erfindungsgemäße Verfahren wird nachstehend ".anhand der Figuren 1 bis 3 näher erläutert.The method according to the invention is described below "using the Figures 1 to 3 explained in more detail.

Figur 2 zeigt die Ausbildung des Düsenkopfes 3, aus dem die beiden Kunststoffprofile austreten. Aus Figur 3 ist die Situation in der Ebene der beiden Kaschierwalzen 7 zu erkennen. Die Metalleinlage β ist hier als Metallband dargestellt. Figure 2 shows the design of the nozzle head 3, from which the two plastic profiles emerge. The situation in the plane of the two laminating rollers 7 can be seen from FIG. The metal insert β is shown here as a metal strip.
Nach dem erfindungsgemäßen Verfahren können sowohl geschäumte als auch kompakte Kunststoffproflie mit Metalleinlagen auf wirtschaftlich Weise hergestellt werden.According to the process of the invention, both foamed as well as compact plastic profile with Metal inserts produced in an economical way will.
