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 the steps of determining digital values proportional to the radiation emitted by hot glass containers immediately after the forming machine with a measurement unit sensitive to the radiation emitted by the hot glass containers, wherein the measurement unit generates a digital image of each hot glass container which is arranged in a finite number of image lines, each image line having a finite number of pixels, each pixel having a digital value, 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 digital values of all of the pixels in all of the image lines for such glass container; b. determining a line radiation measurement for each image line for each glass container by summing the digital values of all of the pixels in such image line for such glass container; c. determining a measurement-ratio curve for each glass container by dividing the line radiation measurements for each image line of such glass container by the total radiation measurement for such glass container; d. determining a reference curve based upon a plurality of the measurement-ratio curves over a predetermined number of the glass containers; and e. determining a relative difference curve for each glass container by subtracting the reference curve from the measurement-ratio curve for such glass container and dividing the result by the reference curve.
