Abstract

See full text

A blowhead (10; 100) for blowing air through a neck opening (12; 112) of a glass parison (14; 114) to cause it to expand. The blowhead defines an air supply passage (28; 128) through which air can enter the parison and an exhaust passage (45; 145) through which air can exhaust from the parison. The cross-sectional area, transversely to the direction of air flow, of at least a portion of the exhaust passage is adjustable.
