ABSTRACT:
Flame seaming a glass sheet of irregular outline using a ring-type burner having an apertured inner wall aligned with the central portion of the glass sheet edge develops an edge of more uniform appearance when the application of a fuel mixture to a portion of said apertured wall facing the glass edge is different for curved portions of the wall facing curved portions of the glass sheet outline than to straight line portions of the wall facing straight portions of the glass sheet outline. Further reduction of non-uniformity of glass edge appearance may result from providing orbital motion between said glass sheet outline and an apertured inner wall of said ring-type burner.
