Title: Polishing method for glass pane
Inventor: OGO MAKOTO
IPC: B24B7/24
Filed: 1988-12-28
Abstract: PURPOSE:To prevent the generation of unpolishing part over the whole length of both long side sides of a glass pane and the generation of crack and chip at the end edge of the long side, by polishing by protruding one part of a polishing machine to the both short side sides of the glass pane. CONSTITUTION:A glass pane11 is placed by fixing it on a surface plate 12. When the side side of the glass pane 11 is moved to the position where it is extruded to the extent of about 1/3 of the diameter of a 1st polishing machine 14, the polishing machine 14 is abutted to the glass pane 11 by descending the 1st polishing head 15 and rotary polishing is started. Thus, the movement is executed in order toward each polishing head 15. At the time when the glass pane 11 is moved to the position extruding about 1/3 of the diameter of the 1st polishing machine 14 to the short side part of the other part becoming at the terminal thereof, the 1st polishing head 15 is ascended by stopping the rotary polishing.
