Claim Text:
1. A method for forming a plastic article having a calibrated neck, using the principles of blow molding and employing a blow mold and a blow pin, said method comprising: initiating an operation sequence with said blow mold in an open position and said blow pin in a retracted or home position; extruding a parison over an inner support; activating a blow pin driver, and causing a shuttle system of a side blow device to operate so as to extend said blow pin sufficiently so as to pierce a side of said parison; retracting an inner support extender, thereby lowering said inner support; closing said blow mold; forming an article neck with said blow pin remaining inside said parison as said mold closes, thereby completing the function of forming an inner diameter of said article neck, and with said article neck being formed on said side of said parison; initiating and activating a forming and cooling cycle; retracting said blow pin; ejecting a resultant plastic article; and repositioning said extender and said inner support to initial positions.
