摘要：
A cutting or bending machine is described with a combined clutch and brake mechanism (1).
Conventionally, combined clutch and brake mechanisms are desirable as they are more compact and cheaper than separate units. However, considerable heat is generated which limits the productivity of a machine with a combined mechanism.
The present invention provides cooling means by way of impeller means (41) and a guide duct (45) directing the air flow uniformly through the entire volume of the combined clutch and brake mechanism (1), preferably to the outer peripheral edges of the mechanism. Thus 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 axially or radially.
