Methods and systems are disclosed whereby the edges of a glass sheet may be beveled with minimal equipment down time. Preferably such methods and systems bevel the upper and lower edges along lateral sides of a glass sheet. In especially preferred embodiments, laterally separated pairs of upper and lower edge grinding assemblies are provided having respective upper and lower oppositely oriented tapered grinding wheels. A glass sheet may thus be moved in a generally horizontal conveyance direction between one of these pairs of upper and lower edge grinding assemblies so that respective upper or lower lateral edges of the glass sheet are brought into grinding contact therewith. Continually moving the glass sheet in the horizontal conveyance direction will therefore present the other lateral edge to the other pair of upper or lower edge grinding assemblies positioned downstream. As such, the other edge will then be beveled. By independently mounting the oppositely oriented grinding wheels for independent movements both horizontally and vertically relative to the glass sheet, a fresh unscored region of the tapered grinding surfaces can then be presented to the glass sheet edges thereby ensuring that the proper bevel angle is achieved.
A method of beveling edges of glass sheets comprising:
A method of grinding upper and lower edges along lateral sides of a glass sheet comprising:
A system for beveling one and another opposed lateral edges of a glass sheet comprising:
An edge grinding assembly for beveling an edge of a glass sheet, comprising:
