As shown in the figure, a plurality of individual sections provided on the rotary table 3 sequentially move in the direction of the arrow and complete one cycle from the gob-in position G to the take-out position TO. This includes the blow molding step and the steps of stopping the rotation of the neck ring and operating the cylinder at the final stage of the blow molding step.

ととなる。The parison 4 molded in the parison molding process is transferred to the blow molding process including the finishing mold 6 and the bottom mold 7 while being suspended by the neck ring 5 (see FIG. 1A). Then, as shown in FIG. 1 (B),
The blow head 8 is placed on the neck ring 5, and the parison 4 is rotated and blow-molded in the finishing mold 6 while injecting blow air. Up to this stage, the process is similar to the conventional blow-molding process, which results in a hollow glass product having a beautiful outer surface without traces of the finish die seams. Further, at the final stage of the blow molding process, as shown in FIG. 1 (C), the four mini cylinders 9 provided in the lower part of the finishing die 6 are activated to form a part of the outer surface of the glass product. Four concave portions 2 will be formed.
That is, as shown in FIG. 2, first, the rotation of the neck ring 5 is stopped (step), and the cylinder 9 is operated with a slight delay (step). When the cylinder 9 is operated, timing air enters from the cylinder head 10 through the pipe (indicated by a broken line) in the finishing die 6, presses the cylinder plunger 11, and the plunger 11 advances into the finishing die 6 to make glass products. 4 concave portions are formed on a part of the outer surface of the.
After that, the timing air is cut off and the plunger 11 is retracted to the original position by the coil spring 12, and the glass product is taken out from the take-out position TO and proceeds to the next step.
この後工程として、上方部分（一般にモイルと称され
る）を切断し最終製品とするが、この工程は従来のもの
と同様である。As a subsequent step, the upper portion (generally referred to as moyle) is cut into a final product, which is similar to the conventional one.
