<P>PROBLEM TO BE SOLVED: To provide a continuous single-side polishing device for glass boards which efficiently performs polishing without generating a polishing scratch. <P>SOLUTION: This continuous single-side polishing device for glass boards having a plurality of polishing disks pushes a glass board to a polishing cloth to polish it, while supplying the polishing liquid. A soft polishing cloth formed from the suede type foaming urethane resin is adhered to, at least, the polishing disk for the final stage of polishing. This soft polishing cloth is formed with the two layer structure of a board surface side non-woven fabric layer 2 and a polishing surface side soft resin layer 3, and the polishing surface is formed with a groove having the same or less depth than the thickness of the soft resin layer formed in the top surface of the non-woven fabric. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
