  • Patent number: 7207866
    Abstract: The present invention is directed to an apparatus for grinding or polishing at least one edge of a glass substrate. The apparatus includes an air bearing support member configured to pivot about an axis of rotation with zero frictional resistance opposing said pivotal movement. A grinding unit is coupled to the air bearing support member. The grinding unit is configured to apply a predetermined force normal to the at least one edge to remove a predetermined amount of material from the at least one edge. The predetermined force is directly proportional to the predetermined amount of material and less than a normal force resulting in glass substrate breakage.

  • Patent number: 7125319
    Abstract: An apparatus and method are described herein which help prevent particles and other contaminants that are generated when an edge of a glass sheet is processed from contaminating or damaging the glass sheet. The apparatus includes an encapsulation device and a processing device. The encapsulation device is capable of supporting two surfaces of a glass sheet. And, the processing device is capable of processing (e.g., cutting, scribing, grinding or polishing) the edge that is adjacent to the supported two surfaces of the glass sheet which are located on a first side of the encapsulation device. The encapsulation device is also capable of substantially preventing particles and other contaminants that are generated when the processing device processes the edge of the glass sheet from reaching the two surfaces of the glass sheet which are located on a second side of the encapsulation device.
