PURPOSE:To especially facilitate the deformation of the freely deformable assembly provided in a parison when the parison is deformed and to certainly restore the assembly after deformation to perform rapid molding. CONSTITUTION:In a blow molding method and apparatus, a freely deformable assembly (A) wherein many piece members (2, 4, 6...) mutually arranged side by side through many elastomere are connected by many wires (8a, 8b...) different in length and the connection state of the piece members (2, 4, 6...) is made freely deformable through the wires (8a, 8b...) is positioned within a parison 20 and the shape of the freely deformable assembly (A) is bent to preform the parison 20 into a predetermined shape and, after a mold is closed, a pressure fluid is supplied into the parison 20 to mold a molded product (B) and the wire members (8a, 8b...) are slackened to remove the freely deformable assembly from the molded product (B). |
