Glass-plate working apparatus

Abstract

A glass-plate working apparatus 1 is comprised of a working head 7 for working an end face in a region R1 of an end face 6 of a glass plate 2; a moving means 10 for moving the working head 7 in an X direction along the end face in the region R1 of the glass plate 2; a working head 11 for working an end face in regions R2 and R3 of the end face 6 of the glass plate 2; and a moving means 12 for moving the working head 11 in the X direction along the end face in the regions R2 and R3 of the glass plate 2.

1 . A glass-plate working apparatus comprising:
 at least one first working head means for effecting grinding or polishing, or both grinding and polishing, of an end face in one region of a glass plate;   a first moving means for moving said at least one first working head means along the end face in the one region of the glass plate;   at least one second working head means for effecting grinding or polishing, or both grinding and polishing, of an end face in another region of the glass plate; and   a second moving means for moving said at least one second working head means along the end face in the other region of the glass plate.   
     
     
         2 . The glass-plate working apparatus according to  claim 1 , wherein said first moving means is adapted to move said at least one first working head means along the end face in the one region of the glass plate to cause said at least one first working head means to work the end face in the one region of the glass plate, and said second moving means is adapted to move said at least one second working head means along the end face in the other region of the glass plate to cause said at least one second working head means to work the end face in the other region of the glass plate. 
     
     
         3 . The glass-plate working apparatus according to  claim 1 , wherein each of said first moving means and said second moving means is adapted to move each of said at least one first working head means and said at least one second working head means such that said at least one first working head means and said at least one second working head means approach each other or move away from each other. 
     
     
         4 . The glass-plate working apparatus according to  claim 1 , wherein said at least one first working head means has at least one grinding wheel or at least one polishing wheel, or at least one grinding wheel and at least one polishing wheel, and said at least one second working head means has at least one grinding wheel or at least one polishing wheel, or at least one grinding wheel and at least one polishing wheel. 
     
     
         5 . The glass-plate working apparatus according to  claim 1 , wherein said first working head means is constituted by a plurality of first working head means, and said second working head means is constituted by a plurality of second working head means.
