    • A method is set forth for forming laminated articles such as by pressing, blowing, and press and blow techniques, directly from a composite gob of molten glass having an inner core of one glass and an outer skin of a second glass. A charge of molten core glass is delivered from one supply of molten glass and a charge of molten skin glass from a separate supply is simultaneously delivered so as to surround the core glass. The composite charge is severed from their separate supplies so as to form a discrete composite gob of molten glass having a core glass encapsulated within a skin glass. The discrete composite charge of molten glass is delivered to a forming mold wherein a positive force such as pressing and/or blowing is applied to said charge of molten glass within the mold to form a laminated article having a core of one glass which is completely surrounded by a skin of a second glass.
    • 提出了一种用于通过压制,吹塑和压制吹塑技术直接从具有一个玻璃的内芯和第二个玻璃的外表皮的熔融玻璃的复合料滴形成层压制品的方法。 从一个熔融玻璃杯供应熔融芯玻璃的电荷,同时输送来自单独电源的熔融皮肤玻璃的电荷,以包围芯玻璃。 复合电荷从其单独的电源切断,以形成具有封装在皮肤玻璃内的芯玻璃的熔融玻璃的离散复合料滴。 将熔融玻璃的离散复合电荷输送到成型模具中,其中在模具内的所述熔融玻璃装料中施加诸如冲压和/或吹塑的正力以形成具有完全包围的一个玻璃的芯的层压制品 由第二玻璃的皮肤。
