More Information
Summary:The invention relates to a method and apparatus for controlling a treatment process in safety glass production by means of information representing a load of glass panels. Flat glass panels are conveyed through a heating lehr (2) and a quenching section (22). The treatment process is preceded by using a line camera (6) for reading the information representing a load of glass. This information is used in controlling the treatment process. The load-representing information is supplemented by automated detection of a glass panel's coating or the absence of coating. A glass panel's thickness is also measured. This information about coating and thickness is used in quenching for automated regulation of a quenching time and a blast pressure. Such information is also particularly useful for the automated control of convection heating (3c) included in the heating device.
