Method of cleaning abrasive plates of abrasive machine and cleaning device

A method of cleaning abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine, which are mutually faced, by a cleaning device including:

• a pivotable nozzle for jetting water toward the abrasive faces of said abrasive plates rotating;
• means for pivoting said nozzle;
• and
• means for moving said nozzle along the abrasive faces,
• said method is characterized by the steps of:
• jetting water from said nozzle toward the abrasive face of said upper abrasive plate;
• moving said nozzle so as to clean the abrasive face of said upper abrasive plate;
• pivoting said nozzle toward the abrasive face of said lower abrasive plate;
• jetting water from said nozzle toward the abrasive face of said lower abrasive plate;
• and
• moving said nozzle so as to clean the abrasive face of said lower abrasive plate.

A method of cleaning abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine, which are mutually faced, by a cleaning device including:

• a first nozzle for jetting water toward the lower abrasive face of said upper abrasive plates rotating, said first nozzle being moved with respect to the lower abrasive face;
• and
• a second nozzle for jetting water toward the upper abrasive face of said lower abrasive plates rotating, said second nozzle being moved with respect to the upper abrasive face,
• said method is characterized by the steps of:
• jetting water from said nozzles toward the abrasive faces of said abrasive plates,
• wherein movement of said second nozzle is a prescribed time behind that of said first nozzle so as to securely remove the water fallen onto the upper abrasive face of said lower abrasive plate.

A cleaning device for cleaning abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine, which are mutually faced, comprising:

• a nozzle for jetting water toward the abrasive faces of said abrasive plates rotating;
• means for moving said nozzle along the abrasive faces;
• 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,
• wherein said closing means closes said gap when said nozzle and said preventing means are moved toward the outer edge of said upper abrasive plate and said gap is formed between said preventing means and the outer edge of said upper abrasive plate.

A cleaning device for cleaning abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine, which are mutually faced, comprising:

• a nozzle for jetting water toward the abrasive faces of said abrasive plates rotating;
• means for rotating said nozzle toward said upper abrasive plate and said lower abrasive plate;
• means for moving said nozzle along the abrasive faces;
• means for preventing the jetted water from scattering in the air;
• and
• means for controlling said rotating means and said moving means,
• wherein said controlling means controls said rotating means to head said nozzle toward the abrasive face of said upper abrasive plate, then said controlling means controls said rotating means to head said nozzle toward the abrasive face of said lower abrasive plate so as to clean the abrasive face of said lower abrasive plate after the abrasive face of said upper abrasive plate is cleaned.

A cleaning device for cleaning abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine, which are mutually faced, comprising:

• a first nozzle for jetting water toward the lower abrasive face of said upper abrasive plates rotating;
• a second nozzle for jetting water toward the upper abrasive face of said lower abrasive plates rotating;
• means for moving said nozzle sections with respect to the upper abrasive faces;
• and
• means for controlling said moving means,
• wherein movement of said second nozzle is a prescribed time behind that of said first nozzle so as to securely remove the water fallen onto the upper abrasive face of said lower abrasive plate.
