To provide a blow molding machine wherein the structure of a heating feed passage is simplified and the feed trouble of the heating feed passage is solved by largely altering the structure of the heating feed passage while improving the feed speed of the blow molding station of chain feed.
The blow molding machine has a heating station in which N preforms P are arranged in the direction crossing a feed direction A at a right angle at a delivery position for delivering the preforms P to the transfer part 5, a gripping mechanism 50 for gripping the N preforms P arranged in the first direction, the transfer part 5 having a direction changeover mechanism 53 for re-arranging the N preforms in the second direction by rotating the gripping mechanism 50, and a blow molding station for blow-molding the N preforms P received from the transfer part 5 in a state arranged in the feed direction A.
