Abstract

Cloth cleaning device of a polishing machine which is capable of fully cleaning a polishing cloth including a part in the vicinity of a center roller. The cloth cleaning device includes an arm movable in a plane parallel to the polishing cloth between a first position above the polishing cloth and a second position outside of the polishing cloth. A jet nozzle is attached to the arm and directs high pressure water toward the polishing cloth. An enclosing member encloses the jet nozzle so as to prevent the high pressure water, which has been directed out from the jet nozzle, from scattering. The jet nozzle is oriented toward the center roller and the high pressure water is directed toward the part of the polishing cloth in the vicinity of the center roller when the arm moves the jet nozzle close to the center roller.
