Gegenstand vorliegender Erfindung ist eine Vorrichtung zum Brechen eines unmittelbar aus dem Schmelzofen kommenden endlosen Glasbandes, nachdem es mit Rillen versehen und auf einem endlosen Förderband abgelegt bezw. gestreckt worden ist. Die Neuerung ist besonders dadurch gekennzeichnet, daß das von der endlosen Streckvorrichtung abgegebene endlose Glasband einem um ein festes LagerThe present invention is a device for breaking a directly endless ribbon of glass coming out of the furnace after grooving it and placed on an endless conveyor belt respectively. has been stretched. The innovation is particularly characterized in that the dispensed from the endless stretching device endless ribbon of glass one around a fixed bearing

to schwingenden endlosen Träger zugeführt, am vorderen Ende des Trägers durch eine schwingbare Rolle niedergehalten und beim Anheben des Trägers abgebrochen wird, wobei zwei schwingende Träger so zusammen arbeiten können, daß der eine das Abbrechen und Weiterführen des abgebrochenen Stückes bewirkt, während der andere Träger dem sich nachschiebenden Glasbande als Führung dient. Die beiliegende Zeichnung stellt den Gegenstand der Erfindung bildlich dar, und zwar zeigt:fed to vibrating endless carrier, at the front end of the carrier by a swingable Roll is held down and broken off when the girder is raised, two swinging girders so working together can that one of them causes the breaking off and continuation of the broken off piece, while the other carrier serves as a guide for the glass ribbon that is sliding behind. The accompanying drawing represents the subject of the invention, namely shows:

Nachdem die endlose Glasplatte E, welche in noch formbarem Zustande aus dem Ofen kommt, auf dem endlosen Träger A gestreckt und mittels eines Rillenrades G gerillt ist, gelangt dieselbe nach dem Abbrechtisch. Dieser Tisch besteht aus zwei Sätzen von endlosen Trägerketten J und L, welche Arme 9 und 10 besitzen, die mit Rollen 11 und 12 ausgestattet sind, und so an den Ketten verteilt sind, daß abwechselnd die Arme des einen und des anderen endlosen Bandes nach oben stehen und das Glas unabhängig von dem anderen tragen. Die Ketten sind über Räder M und JV, Ai¹ und JV¹ entsprechend geführt. Die Räder M und JV sind fest auf einer Welle O und die Räder Af¹JV¹ werden in ihren eigenen Lagern in den gegabelten Enden von Stangen P und R getragen, welche mit dem anderen Ende um die Welle O schwingen und dort mit gegabelten Enden die Naben der Räder AiJV umfassen. Es können sich demnach die Stangen P und R abwechselndAfter the endless glass plate E, which comes out of the furnace in a still malleable state, has been stretched on the endless carrier A and grooved by means of a grooved wheel G, it reaches the break-off table. This table consists of two sets of endless carrier chains J and L, which have arms 9 and 10, which are equipped with rollers 11 and 12, and are distributed on the chains so that the arms of one and the other endless belt alternately upwards stand and wear the glass independently of the other. The chains are guided over wheels M and JV, Ai ¹ and JV ¹ accordingly. The wheels M and JV are fixed on a shaft O and the wheels Af ¹ JV ¹ are carried in their own bearings in the forked ends of rods P and R , which swing with the other end around the shaft O and there with forked ends the AiJV wheel hubs include. The rods P and R can therefore alternate

raise and lower at their free ends with the wheels M1 N1 and if one set of these wheels is up, the other is down and vice versa. When '(Fig. 2) the glass plate E comes in a slightly oblique direction from the carrier A and the break-off roller S has been moved downwards (Fig. 3), the endless carrier J is lifted, at the other end by the swinging one Arms T and the rollers t, which hit the rotatably mounted rods P from below and lift them as well as the carrier 7 running with rollers on P and thereby break through the glass in 1-5 of the transverse direction along the grooved line below the roller S. The broken piece is conveyed on the arms and can be delivered to other conveying devices. Meanwhile, the arms 10 and rollers 12 of the carrier L have come up and support the end of the further sliding glass plate E until the breaking off by lifting the carrier J is repeated. In this way, the carriers take turns guiding the severed glass plates forward. and to get back under the shifting end of the endless glass ribbon. The parts TT1, which carry the roles ff1 ,, and. grab under bars P and R, are mounted in opposite positions on the shaft 20. Two other arms 21 and 22 are mounted on the shaft 20. Separately mounted levers 25 and 26 move the arms 21 and 22 through the tie rods 31 and 32. The position of the levers 25 and 26 is alternately changed by lugs 34 and 35 on the carrier A, which hit one first and then the other, and as a result of this action, the respective rods P and Pv are raised enough at their free ends to cause the glass to be broken off in the transverse direction of the roll S. This is suspended from oscillating arms 37 equipped with a counterweight, to which arms 38 are articulated, which are movably suspended at 39 and which at their other end come into engagement with the extensions 34 and 35. These arms correspond to the length of the used glass plate and can be chosen longer and shorter. Usually the roller S does not lie against the glass sheet and is only pressed downwards when it is moved forward by the arms 38, the rod 39 then disengaging the arms from these projections. The rollers 11 and 12 are loosely seated on their arms so that differences in the speed of the endless carriers and the glass ribbon carried will not cause damage. A sprocket 40 connects shafts O and O1 to transmit movement from A to carriers J and L. A guide roller 41 supports the glass between A and JL. In Fig. 2 and 3, the rails or rods P and R form guide tracks on which the rollers 13 run on the respective upper strand of the endless carrier chains / and L and thus keep these chains in a straight line.
