Abstract:
1. A method for monitoring a glass container forming process wherein the forming process is accomplished by a forming machine which contains multiple independent sections each having at least one forming station at which glass containers are formed, comprising steps of measuring radiation emitted by hot glass containers from the forming stations immediately after the forming machine with a measurement unit sensitive to the radiation emitted by the hot glass containers, wherein the measurement unit generates an image of each hot glass container which is arranged within an associated image area defined by a finite number of image lines, each image line having a finite number of pixels, characterized in that the method further comprises the following steps for each glass container measured from each forming station: a. determining a total radiation measurement for each glass container by summing the image values of all the pixels in all the image lines for such glass container; b. determining a line radiation intensity for each image line for each glass container by summing intensity values of all the pixels in such image line for such glass container; and c. determining an intensity-ratio curve for each glass container by dividing the line radiation intensities for each image line of such glass container by the total radiation intensity for such glass container, thereby to compensate for changes in the amount of radiation emitted by the glass containers resulting from changes in conditions and parameters to which the glass containers are subjected as they travel from their forming stations to the measurement unit.
