Abstract

PURPOSE:To form a projected stopper on the periphery of a straw by supplying a locally heated and pressurized gas into a molding machine. CONSTITUTION:A straw mold 3 is kept opened at the position A under a supply hopper 13. A select gear 14 is turned synchronously with a rotary board 2, and straws 5 are supplied one by one into the straw housing hole 4 of a straw mold 3. When the board 2 is turned to the direction of arrow 16, the mold 3 becomes closed, turned through a given angle, and then stopped at the position B. Hot air is then supplied from a hot air nozzle 9 to the periphery of the straws 5 to heat them and discharged from an exhaust path. After the mold 3 is turned through a given angle and then stopped at the position C, one end of the housing hole 4 is closed, and the heated portion of the peripheral walls of the straws 5 by hot air from the pressure nozzle 10 positioned on the other end is molded into a shape along the recessed groove to form an annular collar. When the mold 3 is turned through a given angle and stopped at the position D, the annular collar is cooled and hardened by cold air from a cold air nozzle.
