(54) Method of taking up wear of a grinding wheel on a machine for grinding sheets of glass, and grinding machine implementing such a method


(57) A method of taking up wear of a grinding wheel (7) on a machine (1) for grinding sheets (2) of glass, whereby the position of an abrasive surface (12) of the grinding wheel, initially set to an ideal work position such as to obtain a sheet of a given size, is adjusted, following wear of the grinding wheel (7), by moving the abrasive surface (12) towards a reference surface (31) on the machine (1), positioned facing and at a predetermined distance (A) from the abrasive surface (12) when the abrasive surface (12) is in the ideal work position; determining the instant of contact between the abrasive surface (12) and the reference surface (31); arresting the grinding wheel (7) at the instant of contact; and moving the abrasive surface (12) away from the reference surface (31) to an adjustment distance at least equal to the predetermined distance (A).
