Problems solved by technology
Leaving the glass sheet on the heated bending iron for longer periods of time will often result in damaged surface areas of the glass sheet in contact with the bending iron
Damage to the glass sheet can lead to deformation of the glass sheet surface, which can render the optical quality of the glass and subsequent transparency unacceptable

Abstract
A furnace for shaping glass sheets for aircraft transparencies using the cut -to-size method includes a preheat and cooling furnace defined as a first furnace, and a shaping furnace. A conveyor geared for reciprocating movement moves a bending iron supporting a glass sheet through the first furnace set to a preheat temperature. The glass sheet supported on the bending iron is heated in the shaping furnace by microwave beams from a gyrotron to heat portions of the glass sheet to be shaped to a complex shape. After the sheet is shaped, the conveyor moves the bending iron supporting the shaped glass sheet from the shaping furnace through the first furnace set to a cooling cycle.
Description
[0001] related application [0002] Bending irons disclosed in US Patent Application Serial No. 13 / 714,494, filed December 14, 2012, entitled "Bending Device For Shaping Glass For Use In Aircraft Transparencies," may be used to practice the invention disclosed herein. The entire disclosure of US Patent Application Serial No. 13 / 714,494 (hereinafter also referred to as "USPA '494") is hereby incorporated by reference. technical field [0003] The present invention relates to heating and shaping systems utilizing microwave focused beam heating, and more particularly, in one non-limiting embodiment of the invention, to a glass pilotline comprising a furnace having two heating chambers, wherein the first a heating chamber for preheating the one or more glass substrates to a first temperature; a second heating chamber maintained substantially at the first temperature and heating and shaping selected portions of the one or more glass substrates using microwave focused beam heating, ...
