<p>Data concerning the volume and/or weight of a glass gob (6) as it drops after being sheared off (by 7) is collected by imaging the gob on to an array of light-sensitive elements such as a CCD array in a camera (10) and electronically freezing the image and calculating gob volume/weight from the image via a microprocessor. Two images viewed at right angles (cameras 10, 15) give improved results. The data derived can be fed back, e.g. via a gob weight controller (13) to control the operation of forehearth equipment (1, 2, 3, 4, 5).</p> |
