A biaxial orientation molding machine (1) is constructed such that supplying and heating of preforms, biaxial orientation molding and a recovering action of molded products are successively carried out by conveying a preform carrier pallet (7) along a conveying path (6) having a closed configuration. The conveying path (6) is a three-dimensional one such that a second conveying path portion (64) for returning to a preform supplying unit (2) a preform, which is made empty after taking out of a molded product, is formed at a much lower position than a first conveying path portion (62), in which heating and biaxial orientation molding are carried out. The second conveying path portion (64) is allowed to pass beneath an underside of a clamping mechanism (41) of a biaxial orientation molding section (4) and is therefore made linear. Accordingly, it is possible to shorten the entire length of the conveying path, realize small sizing and compactness of the machine and to improve a processing efficiency.
