Abstract:
1. A method of introducing cooling air into a glass container in a blow mold at a blow station of an I.S. Machine, the blow station including a guide arm supporting a blow head and a cooling tube arm assembly supporting a cooling tube operatively associated with the blow head, the method comprising: displacing the blow head between a first on blow mold position and a second off blow mold position; providing pressurized air to the cooling tube to blow a parison into the glass container in the blow mold; displacing the cooling tube operatively associated with the blow head between a first up position and a second down position; providing pressurized air to the cooling tube to cool the glass container subsequent to it having been blown; sensing the pressure within the blow head; and controlling the position of the blow head according to a selected pressure profile as a function of pressure sensed within the blow head.
