Abstract
An injection stretch-blow molding apparatus is disclosed. The apparatus includes at least two preform conditioning stations, a molding injection station for initially molding the preform and a blow molding station. Each of the stations is preferably able to process an equal number of preforms at once. The apparatus also includes a turntable and preform supporting jaws connected to the turntable for transporting consecutive sets of preforms made at the injection station to the two conditioning stations alternately, and for transporting sets of preforms alternately from each of the conditioning stations to the blow molding station. This allows all four stations to operate at their respective full capacities, even though conditioning at the conditioning station requires up to twice as long as injection molding or stretch-blow molding.
