The method and apparatus for producing a hollow glass article permit removal of a resulting hollow glass article without severing a moll. By this, glass powder which would otherwise be caused and fallen into the hollow glass article during severing the moil may prevented. The invention also permits elimination of a means for positioning a respective blow head and for stopping rotation thereof. A quantity of molten glass of a disk-shaped configuration is supplied onto a support ring. Each blow head is lowered onto a corresponding support ring. The molten glass on the support ring is held by the blow head by its periphery. Then, the support ring is removed or withdrawn. A quantity of air is blown into the molten glass by means of the blow head so as to form a hollow glass article. Subsequently, the holding ability of the blow head is eliminated, so as to remove or unload the resulting hollow glass article. Alternatively, the support rings may be omitted.
A method of producing a hollow glass article in a blow-and-blow process, comprising the steps of:
A method of producing a hollow glass article in a blow-and-blow process, comprising the steps of:
An apparatus for producing a hollow glass article in a blow-and-blow process, wherein a quantity of molten glass formed into a disk-shaped configuration is formed into a parison, and the parison is blow-molded by supplying a quantity of air into the parison while the parison is located in a blow mold, so as to form the hollow glass article, the apparatus comprising:
An apparatus for producing a hollow glass article in a blow-and-blow process, wherein a quantity of molten glass formed into a disk-shaped configuration is formed into a parison, and the parison is blow-molded by supplying a quantity of air into the parison while the parison is located in a blow mold, so as to form the hollow glass article, the apparatus comprising a plurality of blow heads vertically disposed around a turn table, wherein each of the blow heads is adapted to receive the quantity of molten glass and each of the blow heads comprises holding means for holding the quantity of molten glass by its periphery and blowing means for blowing the hollow glass article from the held quantity of molten glass.
