Abstract
When subdividing sheets of glass, cutting defects near the edge of the sheet are reduced by initiating scoring action at the very edge of the sheet with a scoring wheel which is rolling and under scoring pressure as it contacts the edge. This is accomplished by providing under the scoring wheel a platform whose upper surface is substantially coplanar with or tangential to the upper surface of the glass, so that the scoring wheel rolls off the platform directly onto the glass surface.
