FUSION DRAW APPARATUS AND METHOD OF MAKING A GLASS RIBBON

An apparatus for making a glass ribbon can include a heating plane including a heat footprint facing the surface of an edge director. A projection of the heat footprint in a resultant direction of theheating plane within the heat footprint can intersect the surface of the edge director. In further embodiments, a fusion draw method of making a glass ribbon can include radiating heat within a heatfootprint of a heating plane toward a surface of an edge director. At least a portion of the heating plane within the heat footprint can face the surface of the edge director so that the surface of the edge director is intersected with heat radiating from the heat footprint of the heating plane. 一种用于制造玻璃带的设备可包括加热面，所述加热面包括面向边缘引导件的表面的热覆盖区域。热覆盖区域在热覆盖区域内的加热面的合成方向上的投影可与边缘引导件的表面相交。在另一些实施方式中，制造玻璃带的熔合拉制方法可包括：将加热面的热覆盖区域中的热向边缘引导件的表面辐射。热覆盖区域中的至少一部分加热面可面向边缘引导件的表面，使得边缘引导件的表面与从加热面的热覆盖区域辐射出来的热相交。
