Abstract
In a method of making a gas burner device, there are steps of symmetrically blanking a first metal plate and deforming it so as to form a first intermediate blank having a bulged portion, bending the first intermediate blank at a symmetrical center thereof to provide a first burner flow path with the bulged portion, and joining end portions of the intermediate blank to form a first burner, blanking a second metal plate and symmetrically deforming it so as to form a second intermediate blank having a bulged portion, bending the second intermediate blank at a symmetrical center thereof to provide a cover plate; and encasing at least an upper end of the first burner with the cover plate to form a slit-like sleeve first hole between the first burner and the cover plate, and forming a second burner flow path communication with a second burner suction hole and the slit-like sleeve fire hole so as to provide a second burner.
