Abstract

In the process, (a) an extrudate of a non-vulcanisable material is produced with an upper surface carrying a negative of the profile on the underside of the rubber profile extrudate and acting as a support for the latter, and (b) the superimposed extrusions are subjected to the continuous vulcanising process, the support extrudate of non-vulcanisable material then being recycled to the extruder.

Description

Verfahren und Vorrichtung zur Herstellung empfindlicher Gummiprofile durch Extrusion und nachfolgende Vulkanisation Die vorliegende betrifft ein Verfahren und eine Vorrichtung zur Herstellung empfindlicher Gummiprofile durch Extrusion und nachfolgende Vulkanisation.Method and device for the production of sensitive rubber profiles by extrusion and subsequent vulcanization The present relates to a method and a device for the production of sensitive rubber profiles by extrusion and subsequent vulcanization.

Profile Komplizierterer Formgebung, wie zum Beispiel dünnwandige Schläuche, Profile mit dünnen Lippen usw.Profiles with a more complex shape, such as thin-walled hoses, Profiles with thin lips, etc.

werden zur Vermeidung von Deformationen während der Lagerung, aber auch in der Erweichunhsphase beim Vulkanisieren auf sogenannten Stützleisten abgelogt. Beim Einlogen der Profile in diese Stätzleisten von Hand treten Verdrückungen auf, di die ward minderwertig machen. Es ist ein sehr sorgfältiges Einls en erforderlich. Dieses Verfahren ist umständlich und kostspielig.be used to avoid deformation during storage, however also logged in the softening phase during vulcanization on so-called support strips. When the profiles are inserted into these support strips by hand, indentations occur, to make it inferior. Very careful cashing in is required. This procedure is cumbersome and expensive.

Die Erfindung vermeidet diese Nachteile und schaffe eine Röal#####eit, die bisher manuellen arbeits organge zu automatisieren, dabei gleichzeitig eine Qualitätsverbesserung zu erzielen und die Ware in beliebig langen Strangen zu erzeugten. Die Erfindung erreicht die Vulkanisation dieser sehr ampfindlichen Ware in besonders geschickter weise durch die Verwendung von Mikrowellen.The invention avoids these disadvantages and creates a Röal ##### eit, to automate the previously manual work organs, at the same time to achieve a quality improvement and the goods in strands of any length to generated. The invention achieves the vulcanization of these very sensitive ones Goods in a particularly clever way through the use of microwaves.

Die Erfindung besteht darin, daß unternalb des herzustellenden Gummiprofilstranges ein weiterer zur Stätzung dieses Stranges mit an der Oberseite negativem Profil in bezug auf die Unterseite des herzust;llenden Gummiprofilstran es dienender Strang aus einem extrudierbaren Material hergest llt wird, daß man beide Stränge aufeinanderlie end dem Vulkanisationsvorgang unterzieht und daß acn nach meendigung der Vulkanisation den Stützstrang wieder der Extrusion zuführt. Der Stützstrang kann auch endlos sein, wobei er die funktion eines Transportbandes übernimmt oder auf diesem aufgelegt ist. (Geeignete Materialien: z.Z. Gummi oder PVG).The invention consists in that below the rubber profile strand to be produced another for the etching of this strand with a negative profile on the top with respect to the underside of the rubber profile strand to be produced, it is the strand serving is made from an extrudable material that both strands are placed on top of one another end of the vulcanization process and that acn after the end of the vulcanization returns the support strand to the extrusion process. The support strand can also be endless, where it takes on the function of a conveyor belt or is placed on it is. (Suitable materials: currently rubber or PVG).

Die Erfindung also einen kontinuierlich erzeugten Stützstrang aus nicht vulkanisiertem Material, welcher nach der Vulkanisation immer wieder verwandt werden kann, weil er in seinen Extruder zurückgeführt wird. Da die Mundstücke der beiden extruder sehr dicht andeinander angeordnet werden können, ist eine Ablage des herzustellenden empfindlichen Gummiprofiles sofort nach seiner Extrusion möglich.The invention therefore consists of a continuously generated support strand not vulcanized material, which is used again and again after vulcanization because it is fed back into its extruder. Since the mouthpieces of the Both extruders can be arranged very close to each other is a shelf of the sensitive rubber profile to be produced is possible immediately after its extrusion.

Die Erfindung wird mit einer Vorrichtung durchgeführt, bei der unterhalb des Extrudermundstückes für des herzustellende Gummiprofil ein Mundstück eines weiteren Extruders angeordnet ist, der ein Strongprofil auspreßt, welches an der Oberseite ein negatives Profil in bezug auf die Unterseite des herzustellenden Gummiprofilstranges aufweist.The invention is carried out with an apparatus in which below of the extruder mouthpiece for the rubber profile to be produced a mouthpiece of another Extruder is arranged, which presses out a Strongprofile, which at the top a negative profile with respect to the underside of the rubber profile strand to be produced having.

Zur einwandfreien Vulkanisation dieser sehr empfindlichen Gummiprofilstrange ist es zweckmähig, wenn man Mikrowellen zur Aunheizung benutzt. Vorteilhaft ist es, wenn man bei dem Durchführung der Vulkanisation mit Hilfe von Mikrowellen, bei weniger polaren Gummi-Mischun en, für den Stützstrang Material mit hohen dielektrischen Verlusten benutzt.For the perfect vulcanization of these very sensitive rubber profiles it is useful to use microwaves for heating. Is beneficial it, if one is involved in carrying out the vulcanization with the help of microwaves less polar rubber compounds, for the support strand material with high dielectric Used losses.

Dabei kann man so vorgehen, da man dem Stützmaterial bei der Extrusion eine Form gibt, welche die Einkopplung der elektrischen UHF-Energie begünstigt.You can proceed in such a way that you use the support material during the extrusion gives a shape that favors the coupling of the electrical UHF energy.

Zweckmäßig ist es, wenn ein encloses Förderband für den Stützstrang vorgesehen ist, welches den Stützstrang durch die Vulkanisationsvorrichtung befördert. Der Stützstrang kann dabei eine glatte Ünterseite aufweisen. Sollen jedoch mehrere Stützstränge nebeneinander durch die Vulkanisationsvorricht laufen oder ist wegen der Einkopplung der UHF-Energie eine ständig gleichbleibende Lage des Stützstranges Erforderlich, so ist es zweckmäßig, wenn das Förderband Nuten aufweist, in die ein nach unten keilförmiger Stützstrang einzulegen ist.It is useful if an encloses conveyor belt for the support string is provided which conveys the support strand through the vulcanization device. The support strand can have a smooth underside. However, several should Support strands run side by side through the vulcanization device or is due to the coupling of the UHF energy ensures a constant position of the support strand It is necessary if the conveyor belt has grooves in which a wedge-shaped support strand is to be inserted downwards.

Daswesen der vorliegenden Erfindung ist anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigen: Fig. 1 einen schematischen eines Teiles der Vorrichtung, von derseite gesehen, Fig. 2 einen Schnitt durch den Stützstrang, das herzustellende Gummiprofil und den Obertrum des Förderbandes, Fig. 3 eine Ges #mtdarstellung der Anlage.The essence of the present invention is based on one in the drawing schematically illustrated embodiment explained in more detail. They show: Fig. 1 shows a schematic of part of the device, seen from the side, FIG a section through the support strand, the rubber profile to be produced and the upper strand of the conveyor belt, FIG. 3 shows an overall view of the system.

In einem Extrusier 1 wird Gummi zu einem Strang 3 verarbeitet.In an extruder 1, rubber is processed into a strand 3.

Unterhalb des Mundstückes des Extruders 1 ist ein Extruder 2 vorgesehen, welcher den Stützstrang 4 erzeugt. Beide Stränge laufen auf ein Förderband 6, welches um die Umlenkrollen 5 geliert ist und dessen Obertrum durch den Vulkanisationskanal 7 führt. Am Ende des Förderbandes 6 wird das erzeugte Gummiprofil 3 auf eine Rolle 8 aufgewickelt, während der Stützstrang 4 über die Förderbänder 9,10 in dcn Trichter 11 des Extruders 2 zurückläuft.An extruder 2 is provided below the mouthpiece of the extruder 1, which generates the support strand 4. Both strands run on a conveyor belt 6, which is gelled around the pulleys 5 and its upper run through the vulcanization channel 7 leads. At the end of the conveyor belt 6, the rubber profile 3 is produced on a roll 8 wound up, while the support strand 4 on the conveyor belts 9,10 in the funnel 11 of the extruder 2 runs back.
