A vertical individual section (I.S.) machine for manufacturing glass containers is disclosed in which parisons made in parison molds are lowered into blow molds located under the parison molds without being inverted, where they are blown into glass containers. Optionally, reheat shrouds may be located vertically intermediate the blank molds and the blow molds to reheat the parisons prior to them being blown. The vertical I.S. machine may have multiple sections that are located close adjacent each other, with each section potentially having multiple blank and blow molds.
