  • Patent number: 4525958
    Abstract: An edge grinder includes a shaft for supporting a glass sheet template in spaced relationship to one another. The template and glass sheet are rotated about a sheet axis of rotation and a grinding wheel is rotated about a wheel axis of rotation. The grinding wheel and a template follower spaced from the grinding wheel are biased against the glass sheet and template respectively, to shape the glass sheet to a desired contour as defined by the template. As the grinding wheel engages varying edge damage and/or increased peripheral rotational speed of the sheet, the load on the motor powering the grinding wheel varies as indicated by current input to the grinding wheel motor. Variations in the current input are responded to by selectively varying the rotational speed of the sheet. In this manner, a uniform rate of material removal is maintained to eliminate overheating of the glass edge and grinding wheel during shaping of the glass sheet.
