ABSTRACT:
An apparatus for successively grinding the edges of a series of like, sheetlike articles, such as glass sheets, and especially irregularly shaped glass articles such as automotive windows. The apparatus includes a frame, a table rotatably secured to the frame, a clamp for clamping an article on the table, and a template of the article carried by the table, but at an elevation below that of the article. The apparatus also has a swing arm assembly which carries a spindle near its outer free end, an inner end of the swing arm assembly being pivotally secured to the frame, the swing arm assembly being movable in a plane to move the spindle toward or away from the table. The spindle of the swing arm assembly has a rotatable grinding wheel which is positioned to engage the edge of an article on the table and a motor drive for rotating the grinding wheel. The spindle further has a cam follower which is positioned to engage the edge of the template when the grinding wheel engages the article. The cam follower has a frustoconical outer, template engaging surface, and is translated with respect to the spindle to compensate for grinding wheel wear by changing the diameter of the portion of the cam follower that engages the template.
