Abstract

1366639 Cutting glass PPG INDUSTRIES Inc 14 July 1971 [23 July 1970 1 Sept 1970 11 Jan 1971] 33019/71 Heading C1M Glass is cut by imposing a deep fissure in the glass having a depth of at least 1À5 mm. and subsequently propagating the fissure deeper into the glass. To produce a straight cut edge in flat glass the score is propagated by mechanically tapping the glass beneath the score at one end 32 and running a blowtorch 30 (or other heat source) along the score. If necessary, a force is applied across the deepened score to complete severing. To produce a curved cut edge, a curved score is deepended by tapping the glass from above at the centre of curvature of the score and optionally heating the score, after which edge nicks 70 and a scored cross 72 are made in the glass and the nicks and cross heated to form vents to the curved score to cause severing. A scoring wheel such as that described and claimed in Specification 1,366,640 may be used.
