Abstract
A method and apparatus of cleaning with a roll brush a three-dimensional surface of a curved glass sheet. Levels at both ends of a rotating shaft of the roll brush are independently controlled and an inclination angle of a support frame of the roll brush about the rotating shaft of said roll brush is controlled when the roll brush is moved along the three-dimensional surface. The posture of the roll brush is controlled in such a manner that the rotating shaft of the roll brush becomes substantially parallel to the three-dimensional surface and that a roll brush extended opening of the support frame surrounding said roll brush is directed in a direction substantially normal to the three-dimensional surface. The posture control of the roll brush is carried out in accordance with prestored data sampled along the curved surface of the glass sheet.
