  • Process for the adjustment of the glass temperature in a float glass lehr and float glass lehr in order to bring this process into operation
    Patent number: 4303437
    Abstract: A method and an apparatus for the heat treatment of a float glass ribbon in which a tunnel lehr is provided with arrays of parallel heat-exchange tubes above and below the path of the ribbon and for each of the longitudinally divided zones of these arrays, the tubes are grouped and provided with respective heaters at the upstream end of the zone while all of the tubes at the zone are connected to a flow at the downstream end for drawing the heated air through the tubes. The temperature of the glass ribbon is measured at the upstream end and the throughflow of the individual groups is controlled selectively to ensure a homogeneous temperature distribution in the glass ribbon.
    Type: Grant
