1. A method of cleaning abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine, said upper and lower faces being mutually faced, said method comprising:
providing a cleaning apparatus, said cleaning apparatus including:
a nozzle for jetting water toward the abrasive faces of said abrasive plates rotating;
means for moving said nozzle along the abrasive faces of said upper and lower abrasive plates for cleaning said plates;
means for preventing the jetted water from scattering in the air, said preventing means enclosing said nozzle; and
means for closing a gap between said preventing means and an outer edge of said upper abrasive plate, said gap closing means being disposed planar with said outer edge of said upper abrasive plate;
jetting water from said nozzle toward the abrasive face of said upper abrasive plate;
moving said nozzle toward the outer edge of said upper abrasive plate; and
moving said gap closing means towards said outer edge of said upper abrasive plate for closing said gap when said gap is formed between said preventing means and the outer edge of said upper abrasive plate.
