Patent number: 6857291Abstract: A blow mold assembly for an I.S. machine for blowing a parison of glass and cooling the blown parison into a formed bottle which can be removed from the blow mold. A blow head is lowered onto a blow mold and final air is applied. A predetermined time after the blow head engages the top surface of the blow mold the blow head is lifted a selected vertical distance above the top surface of the blow mold to an exhaust position allowing cooling air to escape from the blow mold. The selected vertical distance is selected so that at least a minimum pressure will continue within the formed bottle. The blow head is maintain at the exhaust position for a predetermined time and then retracted. The selected vertical distance and the predetermined time can be set as desired.Type: GrantFiled: December 5, 2001Date of Patent: February 22, 2005Assignee: Emhart Glass S.A.Inventors: Leo Diehm, F.

Patent number: 6807829Abstract: A blow head is displaced to the “on” position where its lower portion engages the top of a blow mold. Final blow begins and before final blow is completed, the blow head is raised a selected distance and final blow is exhausted between the O.D. of the formed finish and the upwardly defined annular recess in the lower portion of the blow head. The annular recess is concavely curved to direct exhaust air at the finish to cool the finish.Type: GrantFiled: December 5, 2001Date of Patent: October 26, 2004Assignee: Emhart Glass S.A.Inventors: F.
