Abstract
A blow molding apparatus ( ) including four molds ( ) that move into a common parison receiving position ( ) from directions different from the directions that the molds move out of the parison receiving position ( ). When in the parison receiving position ( ), each mold receives, encloses and severs a length of parison then shapes the parison during blow molding. Two molds ( ) alternately move in respective first and second radial directions ( ) from the parison receiving position ( ) to respective first and second outer positions ( ), to a common article take-out position ( ) and then back to the parison receiving position ( ) from a third radial direction ( ). The third radial direction is angularly spaced between the first and second radial directions. Two additional blow molds ( ) alternately move from the parison receiving position ( ) in the respective first and second radial directions ( ) to the respective outer positions ( ), to a common article take-out position ( ) and then back to the parison receiving position ( ) from a fourth radial direction ( ). The fourth radial direction is angularly spaced between the first and second radial directions and is generally opposite the third radial direction ( ).
