Abstract (en)

[origin: WO9939866A1] According to the invention, a propeller with rotating blades is provided as cleaning tool (1) for the working area of chip removal machines. The angle of attack of said blades is regulated in such a way that an air jet supporting the unfolding of the propeller blades (15) is generated. The propeller blade (15) is arranged in a cartridge for exchanging tools replacing a common tool or a tool spindle and serves to automatically air blast the working area for cleaning purposes.
