| 摘要 |
The present invention relates to a method of cutting a sheet glass wherein the surface of a sheet glass is scored in advance with cutting lines on the surface thereof and is carried by a first conveyor system. The sheet is subjected to an almost uniform fluid pressure applied thereto in front and in the rear of a cutting roll disposed adjacent to and at a level not lower than the terminal end of the first conveyor system. When a cutting line scored on said sheet glass is positioned adjacent the top of the periphery of said cutting roll, a part of the sheet glass in front of the cutting roll, which works as a fulcrum, is bent downwardly by the pressure and broken along said cutting line. The pressure fluid is supplied from a fluid supply source via a supply pipe and is jetted from jet-nozzles opening at the bottom of a fluid-jetting device connected to one end of said supply pipe.
