Abrégé

The present invention relates to an air supplying method for a cluster hammer having a nozzle installed, wherein: an air distributing block (1) defining an air distributing nozzle (3) is installed on a lower portion of an air inlet cover (4) in which air for the cluster hammer enters; the hammers (10) are respectively installed on a lower portion of the air distributing block (1); and pressurized air that passes through the air distributing nozzle (3) is supplied to each of the hammers (10), after which the hammers (10) are operated. Even when a hammer (10) mounted on the cluster hammer is in a flushing position, the hammer does not cause problems in the operation of another hammer, and the cluster hammer can operate smoothly. The present invention has the significant effect of smoothly operating a cluster hammer, without a hammer that is mounted on the cluster hammer causing problems in the operation of another hammer even when the first hammer is in a flushing position.
