US Patent:

41370619, Jan 30, 1979

Filed:

Mar 7, 1977

Appl. No.:

5/775132

Inventors:

James D. Mallory - Maumee OH
Richard T. Kirkman - Maumee OH

Assignee:

Owens-Illinois, Inc. - Toledo OH

International Classification:

C03B 916

US Classification:

65232

Abstract:

Apparatus for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities. The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container. A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape. During the transfer of the parisons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the parison.

International Classification:

C03B 936

US Classification:

65 79

Abstract:

Method and apparatus for forming glass containers by the blow and blow process in which a parison mold and blow mold are positioned relative to each other, such that parisons can be transferred by an invert arm. The parisons are formed with their necks down in the parison mold from a charge of glass delivered thereto, and vacuum is applied to the neck mold to settle the molten glass in the neck mold about a special neck pin to thereby form the finish portion of the container. The neck pin is pulled and counterblow of the charge into parison form is accomplished and the parison is transferred from the parison mold to the blow mold where it is expanded into final shape. The parison mold is coated with a "solid film lubricant" which provides a surface that has an insulating effect and requires less "swabbing" over its useable life. A plunger that has a tip that produces less heat removal for the time it is in contact with the charge or gob of glass is used and purging of the vacuum passages in the plunger is carried out each cycle.

US Classification:

Abstract:

A molten glass feeder system and method of controlling the flow of glass through the feeder to deliver a plurality of uniform, molten glass gobs. The feeder has a heavy-walled bowl structure and a heavy-walled bottom transitional member mounted within the lower region of the feeder bowl, the transitional member having substantial height with a circular passageway at its upper region and an elongated slot passageway at its lower region, and an elongated discharge orifice member having a plurality of three or more, and preferably three to six, discharge orifices in lineal alignment with the elongated slot passageway. The feeder permits the simultaneous formation and delivery, when coupled with suitable glass shearing mechanism, of more uniform plural glass gobs having similar weight, temperature and heat characteristics to multiple-cavity gob-fed glass forming machines.
