Abstract

A cutting or bending machine has a combined clutch and brake mechanism cooled by air flow from an electrically powered impeller. A guide duct directs the air flow substantially uniformly through the entire volume of the combined clutch and brake mechanism, preferably to the outer peripheral edges of the mechanism, so that generated heat is dissipated continuously and the machine can be operated more productively. The impeller fan and the guide duct may direct the air flow either axially or radially of the mechanism and the air flow may be either inwardly or outwardly of the mechanism.
