ABSTRACT:
Improved system for the fabrication of preforms used in the production of glass containers in I.S. machines, employing the blow-blow process to reduce the time delay of mechanical movement between the stages of crown formation and commencement of counterblowing, and the increase in counterblowing or molten glass gob inflation, thus improving glass distribution in the walls of the preform as well as in the finished container, resulting in an improved quality container and in increased production.
