<p>A method and apparatus for forming a glass container in a blow-and-blow process. The apparatus includes air flow controller (84) having a housing (86, 88, 90) defining a chamber (98), a piston (96) disposed for reciprocal movement from a first position to a second position within the housing for moving slide block (94) therein, first (108) and second passages (106) extending through slide block (94), a first port (110) in flow communication with first passage (108) and transducer (120) when piston (96) is in its first position to create a negative air flow through first passage (108) and first port (110) when pressurized air flow is induced through transducer (120) to draw a vacuum beneath a gob in a blank mold to a form a finish in the gob and sweep debris away from the gob and blank mold, and a third port (112) in communication with second passage (106) and first port (110) when piston (96) is in its second position to provide pressurized air to the gob.</p> |
