Description
Heizring zum Vulkanisieren flacher Fahrrad-Laufdecken Vulkanisatoren mit Heizschläuchen oder auch zusammenziehbaren metallenen Heizgürteln sind bekannt. Erstere sind jedoch in der Herstellung verhältnismäßig teuer und eignen sich deshalb weniger für die Fahrradbereifung. Letztere sind meist starr und dürften daher nicht für .alle Fälle, namentlich nicht für in den Scheibenformen tiefer eingravierte Reifenmuster, zur Anwendung kommen.Heating ring for vulcanizing flat bicycle treads. Vulcanizers with heating hoses or contractible metal heating belts are known. However, the former are relatively expensive to manufacture and are therefore suitable less for bicycle tires. The latter are usually rigid and should therefore not be used for all cases, especially not for those engraved more deeply in the disc shapes Tire pattern, are used.
Die Erfindung betrifft nun einen U-förmigen Heizring zum Vulkanisieren flacher Fahrrad-Laufdecken, dessen Neuheit darin besteht, daß seine Seitenwände schwalbenschwanzförmig unterschnitten sind und zur Aufnahme einer leicht auswechselharen, mit entsprechend ausgebildeten Seitenteilen versehenen offenen Heizdecke dienen.The invention now relates to a U-shaped heating ring for vulcanizing flat bicycle treads, the novelty of which is that its side walls are undercut in a dovetail shape and to accommodate an easily replaceable hair with appropriately designed side panels, open heating blankets are used.
Wie aus .der Abbildung ersichtlich, wird zum Unterschied von Bekanntem der Preßdruck auf die Laufdecke a mittels einer lose eingelegten, also ohne Befestigungsmittel festsitzenden Heizdecke b, unter gleichzeitiger Anwendung von Preßluft o. dgl., erreicht. Die Heizdecke b ist von einem äußeren U-förmig ausgedrehten Eisenring c, d umschlossen, derart, daß sich die Heizdecke b in demselben frei bewegen, d. h. ohne besondere äußere Einflüsse sich ausdehnenbzw. zusammenziehenkann. Die Querschnittsendene dieser Heizdecke b verlaufen in vorliegendem Fall zugeschäxft aus und passen sich jedesmal durch den Preßdruck in dem äußemen Aufnahmering c an und schließen infolgedessen die Preßluft o. dgl. nach außen selbsttätig ab. Für die Zuführung der Preßluft o. dgl. ist das Ventilloch g vorgesehen. Nach der Vulkanisation und Beseitigung der inneren Preßdrucknüttel, wie Preßluft o. dgl., springt die Preßluftheizdecke wieder in ihre äußere Lage zurück und kann hiernach, nachdem die Heiztrommeli mit der fertig vulkanisierten Laufdecke seitlich verschoben ist, letztere aus dem Vulkanisator mühelos entfernt werden.As can be seen from the illustration, it differs from known the pressure on the tread a by means of a loosely inserted, so without fasteners Fixed electric blanket b, with simultaneous use of compressed air or the like, achieved. The heating blanket b is made of an outer U-shaped twisted iron ring c, d enclosed in such a way that the heating blanket b move freely therein, d. H. expand or can contract. The end of the cross section this electric blanket b run up in the present case and fit each time by the pressing pressure in the outer receiving ring c and consequently close the compressed air or the like to the outside automatically. For the supply of compressed air o. Like. The valve hole g is provided. After vulcanization and removal of the inner Preßdrucknüttel, such as compressed air o. The like., The Preßluftheizdecke jumps again to its outer position and can then after the heating drum finished with the vulcanized tread is shifted sideways, the latter from the vulcanizer can be easily removed.
