Description

Verfahren zum Vorwärmen von zu vulkanisierenden Kautschukplatten oder Gewebebahnen I)ie Erfindung- betrifft ein Verfahren zum Vorwärmen von zu vulkanisierenden endlichen liautschukplatten oder Gewebebahnen auf Vulkanisiermaschinen mit Heiztrommel und endlosem Spannband. Derartige Vulkanisiermaschinell sind in vielfacher Ausführung bekann. Bei allen diesen Maschinen wird jedoch das zu vulkanisierende Gut annähernd tangential der Heiztrommel zugeführt, und zwar derart, daß seine Richtung auf dem Wege von der Vorratstrommel zur Heiztrommel nicht oder nur unwesentlich geändert wird. Insbesondere findet eine solche Änderung der Zuführungsrichtung im Bereich der Heiztrommel nicht statt. Dadurch sind bei allen bekannten Einrichtungen in der bisherigen Bedienungsweise Wärmeverluste durch Abstrahlung nicht zu vermeiden. Abgesehen davon findet eine Vorwärmung der zu vulkanisierenden Werkstoffbahn durch die von der Heiztrommel abstrahlende B'ärme nicht in ausreichendem Maße statt, was in vielen Fällen jedoch für den Herstellungsvorgang außerordentlich wünschenswert ware.Process for preheating rubber sheets to be vulcanized or Fabric webs I) The invention relates to a method for preheating of to be vulcanized finite rubber sheets or webs of fabric on vulcanizing machines with heating drums and endless strap. Such vulcanizing machines are available in multiple designs known. In all of these machines, however, the material to be vulcanized becomes approximate tangentially fed to the heating drum, in such a way that its direction on the Paths from the supply drum to the heating drum are not changed or only slightly changed will. In particular, such a change in the feed direction takes place in the area the heating drum does not take place. This means that in all known facilities in the previous mode of operation, heat losses through radiation cannot be avoided. Apart from that of this, the material web to be vulcanized is preheated by the from The heat radiating from the heating drum does not take place to a sufficient extent, which in many cases Cases, however, would be extremely desirable for the manufacturing process.

Hier setzt die Erfindung ein, indem die vom freien Mantelteil der Heiztrommel abstrahlende Wärme ausgenutzt wird, und zwar zum Vorwärmen des über zwei einstellbare Leitrollen dicht an diesen freien Mantelteil der Trommel annähernd parallel zu diesem herangeführten Gutes. Außer der Vorwarmung des zu vulkanisierenden Gutes wird eine außerordentlich wirksame Abschirmung der geheizten Vulkanisiertrommel und damit eine Verringerung an Wärmeverlusten erzielt. This is where the invention comes into play, in that the free shell part of the Heating drum radiating heat is used, namely to preheat the over two adjustable guide rollers close to this free shell part of the drum approximately parallel to this introduced good. Except for the preheating of the vulcanized A good thing is an extremely effective shielding of the heated vulcanizing drum and thus achieved a reduction in heat losses.

In der Zeichnung ist eine beispielsweise Ausführungsforn1 dargestellt. In bekannter Weise läuft die zu vulkanisierende Stoffbahn 1 über den Alantel einer geheizten Vulkanisiertrommel 2, an dem die Stoffbahn I durch ein endloses Anpreßband 3 an den Mantel der Trommel 2 gepreßt wird. Das Xnpreßhand 3 wird, wie üblich, über Rollen 4, 5 und 6 geführt, wobei die Rolle 6 gewöhnlich als Spannrolle ausgebildet ist. Die fertigvulkanisierte Stop zahn wird auf eine Vorratsrolle 7 aufgerollt. Erfindungsgemäß wird die I,aufrichtung 8 der Werkstoffleahn durch Walzen 9, 10 derart geändert, daß die Stoffbahn vor dem sonst frei sichtbaren Mantel der Vullianisiertrommel eine Art Wand 1 1 bildet. Diese Wand dient zur Abschirmung der Heiztrommel gegen Wärmeverluste. Andererseits nimmt die Stoffbahn oder Platte 1 1 von der Heiztrommel Wärme auf und kommt schon in gut vorgewärmtem Zustand mit dem Heiztrommelmantel in Berührung. Dadurch werden raschere und bessere Vulkanisierergebnisse erzielt. Die Beschaffenheit des fertigvulkanisierten Werkstoffes ist eine bessere, weil die Erwärmung der Stoffbahn nicht wie bisher erst beim Berühren der Heiztrommel plötzlich, sondern durch das Verfahren gemäß der Erfindung allmählich erfolgt. Die Laufwalzen 9, 10 sind verstellbar in der Richtung der Doppeipfeile 12 gelagert, so daß durch entsprechende Einstellung der Rollenachsen jeder beliebige Grad an Vorwärmung erzielt werden kann. An example embodiment is shown in the drawing. In a known manner, the fabric to be vulcanized 1 runs over the aluminum jacket heated vulcanizing drum 2, on which the fabric web I by an endless pressure belt 3 is pressed against the shell of the drum 2. The Xnpreßhand 3 is, as usual, over Rollers 4, 5 and 6 out, the roller 6 usually designed as a tensioning roller is. The fully vulcanized stop tooth is rolled onto a supply roll 7. According to the invention, the I, erecting 8 of the material flap is made by rollers 9, 10 in such a way changed that the length of material in front of the otherwise freely visible coat of the Vullianizing drum a kind of wall 1 1 forms. This wall serves to shield the heating drum against Heat losses. On the other hand, the sheet of material or plate 1 takes 1 from the heating drum Heat up and comes in a well-preheated condition with the heating drum jacket in touch. This results in faster and better vulcanization results. The quality of the fully vulcanized material is better because the The fabric does not suddenly heat up when you touch the heating drum, as was previously the case, but is done gradually by the method according to the invention. The rollers 9, 10 are adjustable in the direction of the double arrow 12 so that by appropriate adjustment of the roller axes any degree of preheating achieved can be.
