Abstract

PURPOSE:To obtain said bottles at a low cost from a parison of continuous length by a device of a simple mechanism, by heating a parison for molding a plurality of bottles in a heating oven to a stretching temperature and stretching simultaneously each bottle part of the parison via a pantograph mechanism. CONSTITUTION:A parison 1 is heated in a heating oven to a stretching temperature and held by clamps 3 of a stretching apparatus at regular intervals, and a plurality of all bottle parts is simultaneusly stretched longitudinally by a cylinder device 5 via a pantograph mechanism 4. Then, a stretching apparatus 2 is titled by 90 deg. as it is, each bottle part of the parison 1 is held by an upper mold 22 and a lower mold 23 of a molding machine 21 and the parison 1 is cut into each bottle. Then, by blowing air into each bottle via a needle provided at either of molds 22, 23 a bottle of a predetermined shape is formed by lateral stretching and a molded bottle is obtained.
