Apparatus and method for sequential pressing to form glass-based articles

A method of forming a glass-based article is provided that includes depositing molten glass onto a first molding member and pressing the molten glass between the first and second molding members by moving the first and second molding members toward each other. The pressing of the molten glass includes moving a portion of one of the first and second molding members relative to a remaining portion of the molding member to form a first reduced area pressed zone, and after forming the first reduced area pressed zone, moving the portion relative to the remaining portion to form a second reduced area pressed zone, wherein the molten glass is compressed between the first and second molding members. 提供了一种形成玻璃基制品的方法，其包括将熔融玻璃沉积到第一模制构件上并通过使第一模制构件和第二模制构件朝向彼此移动来压制在第一和第二模制构件之间的熔融玻璃。熔融玻璃的压制包括相对于第一和第二模制构件中的一个的剩余部分移动该模制构件的一部分以形成第一减小面积的压制区，并在形成第一减小面积的压制区之后相对于所述剩余部分移动所述部分以形成第二减小面积的压制区，其中熔融玻璃在第一和第二模制构件之间被压缩。
