Vertical I.S. machine

A vertical I.S. machine, comprising:

• at least one blank mold;
• a gob delivery mechanism for delivering a gob of molten glass to the at least one blank mold;
• at least one plunger for removable insertion into the at least one blank mold to form a parison in the at least one blank mold from the gob of molten glass;
• at least one reheat shroud located below the at least one blank mold;
• a first transfer mechanism to lower the parison formed in the at least one blank mold to the at least one reheat shroud;
• at least one blow mold located below the at least one reheat shroud;
• a second transfer mechanism to lower the parison from the at least one reheat shroud to convey it to the at least one blow mold;
• a blow head for removable placement onto the at least one blow mold to blow the parison into a glass container;
• and
• a takeout mechanism to remove the glass container from the blow mold.
