[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically cutting an automobile glass sheet such as an automobile door glass and a backlight glass from a sheet glass into a required shape according to a cutter cutting line inserted in the sheet. It is easy to fold and fold, and it is possible to cause a nick (break) as shown in the above cut line. The present invention relates to a glass sheet folding apparatus.

At present, automobiles are becoming more and more sophisticated, and in connection with this, automobile glass is becoming increasingly thicker (5 mm to 6 m).
m thickness). In this way, when the glass plate becomes thicker, the cutter pressure is increased, and even if a cutting line is made, the new (progress of the crack) does not enter sufficiently, and in the case of a forced break by a machine, it does not break well as the cutting line, At other times, cracking does not occur, and that part remains.

[0003]
