Abstract
Description
Verfahren zu Herstellung @@@ Stahldrahtkernen Method of manufacturing @@@ steel wire cores
für die Wülste von Luftreifer Die Erfindung betrifft ein Verfahren zur Herstellung von Stahldrahtkernen für die Wülste von Luftreifen mit einem auf der Rückenfläche des Stahldrahtkernes angeordneten Profil aus Gummi oder dgl., wobei der für sich hergestellte Stahldrahtkern mit einem Gummiprofil belegt wird. for the beads of pneumatic tires The invention relates to a method for the production of steel wire cores for the beads of pneumatic tires with a the back surface of the steel wire core arranged profile made of rubber or the like., wherein the steel wire core produced for itself is covered with a rubber profile.
Diese so belegten Kerne werden unmittelbar oder aber auch nach einer Ummantelung der Reifenkonfektion zugeführt. These cores so occupied are immediately or after a Coating supplied to the tire assembly.
Nach bekannten Vorschlägen wird jeder Stahldrahtkern fijr sich.mit einem Gummiprofil-be'-egt. According to known proposals, each steel wire core is individually a rubber profile-be'-egt.
Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, das eingangs erwähnte Verfahren so zu verbessern, daB unter Verwendung vergleichs- -weise einfacher technischer Mittel die Herstellung wesentlich schneller vonstatten gehen kann. The invention is essentially based on the object to improve the mentioned method so that it is comparatively easier to use technical means the production can take place much faster.
Zur Lörung dieser Aufgabe werden mehrere Stahldrahtkerne koaxial-angeordnet, mit einem aus Gummi oder dgl. bestehenden Profil belegt, und dann wird dieser Streifen in einzelne Gummiprofile aufgeteilt, die der Breite der einzelnen Stahldrahtkerne entsprechen. Wichtig ist somit, daß nunmehr eine größere Anzahl Kerne zunächst zu einem Paket zusammengefaßt wird, worauf dieses mit dem genannten Streifen belegt wird. Nachdem dieser Streifen in einzelne schmale Profile aufgeteilt worden ist, fallen die einzelnen Stahldrahtkerne mit den hierauf befindlichen profilen an. To solve this task, several steel wire cores are arranged coaxially, with a profile made of rubber or the like. Covered, and then this strip divided into individual rubber profiles that correspond to the width of the individual steel wire cores correspond. It is therefore important that a larger number of cores is initially added a package is summarized, whereupon this occupies with the said strip will. After this strip is divided into individual narrow profiles been is, the individual steel wire cores fall with the profiles on them at.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen: Fig. 1 eine Vorrichtung zum lierstellen von Stahldrahtkernen fiir die Wülste von Luftreifen in schematischer Darstellung in der Seitenansicht, Fig. 2 einen Schnitt nach der Linie II-II von Fig. 1 und Fig. 3 einen Schnitt nach der Linie III-III on Fig. 1.An exemplary embodiment of the invention is shown in the drawing. The figures show: FIG. 1 a device for placing steel wire cores for the Bead of pneumatic tires in a schematic representation in the side view, FIG. 2 a section along the line II-II of Fig. 1 and Fig. 3 is a section according to the Line III-III of Fig. 1.
Auf einer Führungsrolle 1 sind zwischen den beiden Endflanschen 2 dieser Ro]le dicht bei dicht fünf Stahldrahtkerne a nebeneinanderliegend angeordnet.On a guide roller 1 between the two end flanges 2 this roller is arranged close to one another with five steel wire cores a close to one another.
Diesen Stahldrahtkernen a wird über eine Führungsschiene 3 ein Gummistreifen b zugeführt; das Andrücken erfolgt iiber eine Andrückrolle 4. Der Streifen b entspricht der Breite aller Stahldrahtkerne 4.These steel wire cores a become a rubber strip over a guide rail 3 b fed; the pressure is applied via a pressure roller 4. The strip b corresponds to the width of all steel wire cores 4.
Mit der Zuführbewegung des Streifen b werden die Stahldrahtkerne a gedreht, wobei der Streifen b in den Bereich eines rotierenden Messers 5 gelangt, dessen vier Kreismesser zwischen die fünf Stahldrahtkerne 4 greifen und dabei fünf. Stahldrahtkerne a mit den darauf befindlichen gewünschten Profilen c gebildet.With the feeding movement of the strip b, the steel wire cores a rotated, whereby the strip b comes into the area of a rotating knife 5, the four circular knives grip between the five steel wire cores 4 and five. Steel wire cores a formed with the desired profiles c located thereon.
Nach Abheben der Elemente 4 und 5 können die fünf Stahldrahtkerne entfernt und weiterverarbeitet werden.After lifting off elements 4 and 5, the five steel wire cores removed and processed further.
Der Streifen b ist nach dem Ausflihrungsbeisplel einstückig mit rechteckigem Querschnitt ausgeführt. Es ist aber auch möglich, an den Streifen b an den Stellen, die einer Trennfuge zwischen aufeinanderfolgenden Stahldrahtkernen c benachbart liegen,- von vornherein längs verlaufende Einschnitte oder Perforationen vorzusehen, um gegebenenfalis unter Verzicht auf das Trennmesser 5 die Trennung der einzelnen Stahldrahtkerne durch eine Abreißbewegung von-Hand herbeiführen zu können.According to the design example, the strip b is in one piece with the rectangular one Cross-section executed. But it is also possible to use the strips b at the points adjacent to that of a parting line between successive steel wire cores c - provide longitudinal incisions or perforations from the outset, in order, if necessary, without the cutting knife 5, the separation of the individual To be able to bring about steel wire cores by hand with a tearing movement.
