    摘要： A succession (8) of glass sheets (2) is fed in a longitudinal direction (6A) at a predetermined speed and through a grinding station (13), in which a perimeter surface (5) of the glass sheets (2) is first ground by means of one or more grinding wheels (22) and then polished by means of one or more polishing wheels (27); during the grinding and the polishing, the current absorbed by each of the electric motors (23)(28) rotating the wheels (22)(27) is detected, compared with a corresponding predetermined limit value of current that can be absorbed by the electric motor (23)(28) and, when above this, continuing to feed the succession (8) of glass sheets (2) in the longitudinal direction (6A), reducing at least one of either the relative sheet-wheel speed and the thrust action of the polishing wheels (27) against the glass sheet (2) being processed.

    摘要： A succession (7) of glass sheets (2) arranged at a predetermined distance (D) from each other is fed along a longitudinal direction (12) and through a grinding station (13), in which a peripheral surface (5) of the glass sheets (2) is progressively ground through a row (A) of grinding wheels (22) arranged side-by-side in a direction parallel to the longitudinal direction (12); during the grinding of the sheets (2) the wear of at least one first grinding wheel (22') is detected and the same first grinding wheel (22') is repositioned, keeping the succession (7) of sheets moving through the grinding station (13) and in a time period ranging between the moment in which a tail of a sheet (2') being ground on the first grinding wheel (22') has left the first grinding wheel (22') and before a head of a consecutive sheet (2') to be ground reaches the first grinding wheel (22').
