The disadvantage of this method is that many models have to be used, these models have to be filled and emptied, and the expanded glass sheet has to be cut into pieces
In addition, the disadvantage of this known method is that the glass that has just been produced is used as a raw material that must be ground into powder

Embodiment Construction
[0041] In the left half of FIG. 1, a horn-shaped feeding device 1 is shown, with which a mixture 2 of foaming agent and glass frit is evenly distributed via a feeding roller 14 to the circulating conveyor 3 on. A bulk material 15 is thus formed on the endless conveyor belt 3 , which is conveyed by the endless conveyor 3 at a defined speed through the foaming furnace 4 .
[0042] A heating device (not shown) is provided in the foaming furnace 4 , which heats the mixture 2 or bulk mass 15 to approximately 600° C. to 950° C., in particular 800° C. to 850° C. This starts the foaming process and forms a continuous foamed glass gob 16 which is fed directly into the cooling furnace 5 in a continuous manner.
[0043] Corresponding conveying devices 7 and 8 are provided in the cooling furnace 5 , and these conveying devices continue to convey the foamed glass gob 16 . Obviously, it is possible to provide several cooling furnaces or sections with several conveyors arranged one behind ...

Abstract
The invention relates to a device for lifting and stabilising loads, comprising a frame (5) and a height-adjustable crossmember (3), which is located below said frame, bears the load and is stabilised by two intersecting telescopic struts (11) that are hinged on the crossmember so that they can pivot, said struts being in turn secured against modifications in length by means of two stays (14, 15). The aim of the invention is to improve the device to facilitate the stable, swing-free transportation of loads in and against the direction of travel with a simple, lightweight construction. To achieve this, each stay (14 and 15), which is deflected by a deflection pulley provided on the frame (5) or crossmember (3) in the vicinity of the hinged ends of the telescopic struts (11), is guided in a parallel manner to or in an essentially coaxial manner with the pivoting axis (18) of the telescopic strut (11) to an additional (third) deflection pulley (20) and is then conducted to the other respective telescopic strut (11).
Description
technical field [0001] The invention relates to a device and a method for producing foamed glass, said device comprising a foaming furnace in which foamed glass gobs are continuously produced; said method comprises a The foamed glass is foamed into a continuous foamed glass blank by heat treatment. Background technique [0002] Foamed glass has long been known. In European patent EP 12 114 B1 a method for producing expanded glass particle products is described. According to this method, a mixture of ground glass powder and a pasty foaming agent consisting of water, water glass, glycerin and napentonite is formed, this mixture is dried, and after adding a certain amount of glass powder Foaming takes place in a track furnace. The mixture of foaming agent and glass powder is sent through the furnace by means of an endless conveyor belt, so that a foamed glass gob is made by heating and assisted by the blowing agent, and the foamed glass gob is sintered with many pores glass...
