METHODS AND APPARATUSES FOR FABRICATING GLASS ARTICLES

摘要

Methods of fabricating formed glass articles are described herein. In one embodiment, a method for fabricating a formed glass article may include forming a glass ribbon, forming a parson, and shaping the parson to form a glass article. The glass article may be attached to the glass ribbon at an attachment region defining an edge of the glass article. The process may also include contacting the attachment region with a focal line of a laser beam and separating the glass article from the glass ribbon at the attachment region. The attachment region may be perforated by the laser beam and the focal line may be substantially perpendicular to the plane of the glass ribbon.

1. A method of fabricating a formed glass article, the method comprising:
forming a glass ribbon comprising a substantially planar topside and a substantially planar underside; forming a parson comprising glass of the glass ribbon, the parson attached to the glass ribbon at an aperture formed in the glass ribbon, wherein the parson is hollow with an opening at the aperture of the glass ribbon and extends from the underside of the glass ribbon; shaping the parson to form a glass article, the glass article attached to the glass ribbon at an attachment region, the attachment region comprising an area proximate the edges of the aperture, the attachment region defining an edge of the glass article; and contacting the attachment region with a focal line of a laser beam such that the attachment region is perforated by the laser beam, wherein the focal line is substantially perpendicular to a plane of the glass ribbon; and separating the glass article from the glass ribbon at the attachment region.
