PURPOSE:To supply a label to both faces of a cavity by operation of one time even when remarkable distance difference is present in the mold opening position by moving the inside split mold to a mold closing holder before a label holder is inserted and equally regulating the mold opening positions of both split molds while keeping a parting line as a center. CONSTITUTION:In the split molds 11a, 11b, since a preform is sent between the molds from the side part in such a state that an arc is drawn and also a molded form is sent out to the opposite side part in the same state, the moving range of the inside split mold 11b is made large. When the inside split mold 11b is retreated and moved larger than the outside split mold and mold opening is completed and the molded form is sent out to the side part from the blow mold, the inside split mold 11b is advanced and moved in the mold closing direction. When the distance of this split mold for a parting line is made equal to the distance between the parting line and the outside split mold 11a, the inside split mold is once stopped. Then a holder 16 having a label on both side faces is inserted between molds from the side part. The label is supplied to both faces of the cavity after stopping. |
