Description
Vorrichtung zum Transport von auf die Erweichungstemperatur *Device for transporting to the softening temperature *
erhitzten Glasscheibenheated panes of glass
Die deutsche Patentanmeldung P 15 96 369.6 hat eine Vorrichtung zum Transport von auf die Erweichungstemperatur erhitzten Glasscheiben mit starren, undeformierbaren und auf Betriebstemperatur befindlichen Rollen, welche die Glasscheiben transportieren, zum Gegenstand, die dadurch gekennzeichnet ist, daß die Rollen eine nachgiebige, aus einem feuerfesten Fasermaterial bestehende Lauffläche aufweisen, welche bei Arbeitstemperatur nicht durch Dehydratisierung oder chemische Zersetzung zerstört wird. Die vorliegende Erfindung ist ein Zusatz zu dieser Patentanmeldung.The German patent application P 15 96 369.6 has a device For the transport of glass panes heated to the softening temperature with rigid, non-deformable and at operating temperature located rollers which transport the glass panes to the object, which is characterized in that the rollers have a flexible tread made of a refractory fiber material, which does not pass through at working temperature Dehydration or chemical decomposition is destroyed. The present invention is an addition to this patent application.
Eine solche Transportvorrichtung kann z.B. in einem Erhitzungsofen für das Vorspannen von Glasscheiben angeordnet sein, d.h. in einem Ofen, in welchem die Temperatur 8000C erreichen kann.Such a transport device can, for example, in a heating furnace for tempering glass panes arranged to be, ie, in a furnace in which the temperature can reach 800 0C.
Nach der Lehre des Hauptpatents kann die Lauffläche der Rollen insbesondere mit einer kontinuierlichen Schicht ohne Überdeckung ca€i- örtliche Dickenüberschreitung versehen sein, wobei diese nachgiebige umkleidung aus feuerfesten Mineralfasern, wie z.B. SiliciumfaBern, besteht.According to the teaching of the main patent, the running surface of the rollers in particular, be provided with a continuous layer without covering approx. local excess thickness, this flexible cladding made of refractory mineral fibers, e.g. Silicon fibers.

Das Hauptpatent lehrt weiter, daß die nachgiebige Umkleidung der Rollen in der Weise erzielt werden kann, daß auf die zu umkleidenden Förderrollen Bänder aus Fasermaterial spiralförmig so aufgewickelt werden, daß eine sich nicht überdeckende, ununterbrochen durchlaufende Schicht gebildet wird.The main patent further teaches that the flexible casing of the Rolling can be achieved in such a way that on the to be encased Conveyor rollers ribbons of fiber material are spirally wound so that a non-overlapping, uninterrupted continuous layer is formed.
Bs wurde nun gefunden, und dies ist die Aufgabe der vorliegenden Erfindung, daß besonders vorteilhafte Ergebnisse dann erreicht werden, wenn die Umkleidung der Rollen von einem aus feuerfesten lasern bestehenden Filzband gebildet wird. Ein solches Pilzband ist leicht spiralförmig auf die Rollen aufzuwickeln und sein Anhaften kann durch ein Klebemittel in Form einer an der Luft trocknenden, feuerfesten Zementschicht bewirkt werden, die vorher auf die Rollen aufgebracht wurde.Bs has now been found, and it is the object of the present invention, that particularly advantageous results are then achieved if the covering of the rolls is formed by a felt tape made of fireproof lasers. Such a mushroom ribbon is easy to wind up in a spiral on the rolls and its sticking can be achieved by an adhesive in the form of an air-drying, refractory cement layer, which was previously applied to the rollers.
So wurden beispielsweise ausgezeichnete Ergebnisse mit Hilfe eines Filzbandes aus Aluminiumsilikatfasern erzielt, wie sie von der Firma Carborundum unter dem Handelsnamen "1IBERJ1RAX" vertrieben werden. Es handelt sich hier um keramischen Filz aus feuerfesten, kurzen Aluminiumsilikatfasern, die etwa wie Löschpapierfasern aussehen und eine Dicke in der Größenordnung von 0,5 mm aufweisen. Dieser Filz wird in Form von Rollen von 50 oder 100mm Breite verkauft.For example, excellent results were achieved with the aid of a felt tape made of aluminum silicate fibers, such as those sold by the Carborundum company under the trade name "1IBERJ 1 RAX". It is a ceramic felt made of fire-resistant, short aluminum silicate fibers, which look roughly like blotting paper fibers and have a thickness in the order of magnitude of 0.5 mm. This felt is sold in the form of rolls of 50 or 100mm width.
Die Transportrollen eines Erhitzungsofens zum Vorspannen von Glas wurden mit einem solchen Filz umkleidet £ der Durchmesser der Rollen betrug 60 mm. Der Ofen wurde bei Temperaturen von 780 bis 8000C gehalten.The transport rollers of a heating furnace for toughening glass were covered with such a felt, the diameter of the rollers was 60 mm. The furnace was held at temperatures of 780-800 0 C.
Aus den angestellten Versuchen haben sich die folgenden Vorteile einer Verkleidung gemäß der vorliegenden Erfindung ergeben!From the experiments made, the following advantages of a cladding according to the present invention have emerged!
- Der in Frage stehende Filz behält seine Nachgiebigkeit bei den obengenannten hohen Temperaturen?- The felt in question retains its flexibility at the high temperatures mentioned above?
- Die Oberfläche der Verkleidung ist weicher, glatter und homogener als diejenige von Verkleidungen aus gefloohtensn oder- The surface of the cladding is softer, smoother and more homogeneous than that of cladding made of fled or

gewebten lasern, so daß eine Markierung der Glas Scheiben durch die Tragrollen nickt mehr zu "befürchten ist, selbst im Pail sehr dicker Glasscheiben, und zwar wegen der Vergrößerung der Berührungsfläche und der daraus sieh ergebenden Verminderung der Kraft pro Flächeneinheit.woven lasers, leaving a mark on the glass panes through the idlers nods more to "fear", even in the pail very much thick panes of glass because of the increase in the contact area and the resulting reduction in force per unit area.
Im übrigen nützt sich die erfindungsgemäße umkleidung nicht mehr ab als di© aus gewobenen oder geflochtenen Fasern gebildeten Umkleidungen. In addition, the casing according to the invention does not wear out more than the casing formed from woven or braided fibers.
Schließlich ist äas Aufbringen des Pilz'bandes auf die Rollen sehr leicht zu bewerkstelligen^ wobei jegliche Überdeckung der 3?ilzspiralen dadurch. vermieden werä®n kann, daß zwischen jeder Spirale ein Zwischenraum von mindestens einem Bruchteil eines Millimeters freigelassen wird, d©r ohne weiteres bis au einem Millimeter groß sein kann, so daß keinerlei Bindruck auf den Glasscheiben hervorgerufen wird-»Finally, the mushroom tape is applied to the rollers very easy to accomplish ^ with any overlap of the 3? Felt spirals through it. it can be avoided that between everyone Spiral an interval of at least a fraction of one Millimeter is left free, which can easily be up to one millimeter in size, so that no impression whatsoever on the Panes of glass is caused- »
