Patent ID: 6887140

Claim:
A machine for radiusing the corners of glass sheets (K) by tools (A, B, C), comprising: three different coaxial tools (A, B, C); an electric motor ( 33 ) driving the three different coaxial tools; a first drive means ( 46 ) for vertically moving the electric motor ( 33 ); a first support structure ( 34 ) supporting the first drive means ( 46 ) and supporting the electric motor ( 33 ) so that the electric motor is vertically movable by the first drive means ( 46 ); a rotatable pin ( 17 ) defining a vertical axis (Y); a second support structure ( 13 ) rotatably supporting the pin and rotatably supporting the first support structure about the vertical axis (Y); second support structure ( 13 ) movable horizontally in two mutually perpendicular directions (X, R); an intermediate member ( 27 ) slidingly engaged, in an undercut manner, with the first support structure ( 34 ); the pin being slidingly engaged in an undercut manner with the intermediate member ( 27 ); a second drive means ( 40 ), supported by the intermediate member ( 27 ), operationally connected to said first support structure ( 34 ); and a screw means ( 29 ); the intermediate member ( 27 ) cooperating with the pin ( 17 ) via the screw means ( 29 ) for setting the radius of curvature of a radiusing operation.
