Patent ID: 8857213

Claim:
A system for correcting deficiencies in vertical glass distribution, comprising: a glass distribution measurement system configured to generate a measured glass distribution indicative of actual vertical glass distribution in blown parisons; the system configured to be provided with a desired vertical glass distribution; a summer configured to compare the measured glass distribution with the desired vertical glass distribution and to generate a vertical glass distribution error signal indicative of the result of the comparison of the measured glass distribution with the desired vertical glass distribution; a final blow controller configured to use the vertical glass distribution error signal to generate a start of final blow signal configured to modify the timing of the start of final blow to vary the stretching of a parison in a blow mold prior to the parison being blown in a manner that will cause the vertical glass distribution error signal to be diminished; and a parison mold cooling controller that is arranged and configured to selectively vary the cooling time of a parison mold.
