    • The present invention is directed to an improved method of manufacturing tempered glass sheets on a continuous basis from a band drawn from a melt, and to an improved method of cutting bands of hot glass. The method is characterized by subjecting a continuous ribbon or band of glass emerging from a glass fabricating furnace or from the terminal stages of a float process, the glass being at a temperature suitably high for subsequent tempering, e.g., preferably at or near the annealing point, to a cutting procedure involving drawing a scoring implement pressed against the surface of the band transversely across the band, the tip portion of the scoring implement being continuously supplied with limited quantities of a liquid, the quantities being sufficient to flow or be drawn into the minute fissures formed by the scoring implement but not so great as to flow or engage to any significant extent glass portions beyond the score line. The thus scored glass, preferably promptly after the formation of the score, is flexed about a bending axis coincident with the score to separate the increments of the band along the score line, the separated increment being thereafter subjected to quenching influences.
    • 本发明涉及一种从熔融物拉伸的带上连续地制造钢化玻璃板的改进方法,以及一种切割热玻璃带的改进方法。 该方法的特征在于对来自玻璃制造炉或浮法工艺的末级阶段的连续玻璃带或玻璃带进行处理,玻璃的温度适当高于后续回火温度,例如优选在退火点处或附近 涉及一种切割过程,包括拉伸压带横向穿过带的表面的刻痕工具,刻痕工具的尖端部分被连续地供给有限数量的液体,其数量足以流动或被吸入 由分数工具形成的微小的裂缝,但不太大以至于超过刻痕线的任何显着程度的玻璃部分流动或接合。 这样得分的玻璃,优选在分数形成之后迅速地绕与分数重合的弯曲轴线弯曲,以便沿着刻痕线分离带的增量,此后分离的增量随后进行淬火影响。
