A BIAXIALLY STRETCHING BLOCK MOULDING APPARATUS WHICH HAS HIGH PROCESS SPEED BY IMPROVING EFFICIENCY OF OPERATION IN RESPECTIVE COMPONENTS. THE BIAXIALLY STRETCHING BLOW MOULDING APPARATUS PERFORMS BIAXIAL STRETCH-MOULDING FOR A PREFORM (P) INTO A PREDETERMINED SHAPE BY TRANSPORTING A PREFORM CARRIER (7) SUPPORTING THE PREFORM (P) ALONG A TRANSPORTING PATH (8(2)) EXTENDING ACROSS A HEATING PORTION (4) AND A STRETCH-MOULDING PORTION (5), HAS FIRST (31) AND SECOND REVERSING MEANS (61) FOR REVERSING THE PREFORM CARRIER (7), AND FIRST AND SECOND TRANSPORTING PATHS FORMING THE TRANSPORTING PATH (8(2)). THE FIRST REVERSING MEANS (31) RECEIVES THE PREFORM CARRIER (7) TRANSPORTED IN UP-SIDE- DOWN POSITION ALONG THE SECOND TRANSPORTING PATH, REVERSES THE RECEIVED PERFORM CARRIER (7) INTO ELECTED POSITION, AND TRANSFERS THE PREFORM CARRIER (7) THUS REVERSED TO THE FIRST TRANSPORTING PATH. THE SECOND REVERSING MEANS (61) RECEIVES THE PREFORM CARRIER (7) TRANSPORTED IN ELECTED POSITION ALONG THE FIRST TRANSPORTING PATH, REVERSES THE RECEIVED PREFORM CARRIER (7) INTO THE UP-SIDE-DOWN POSITION, AND TRANSFERS THE PREFORM CARRIER (7) THUS REVERSED TO THE SECOND TRANSPORTING PATH.
