Abstract
An apparatus and a method for producing a heat dissipating element having a multiplicity of pins arranged in parallel rows and columns in longitudinal and transverse directions from a generally longitudinally extending extruded member having a base and a number of transversely spaced longitudinally extending ribs on the base. A cover frame having a number of transversely spaced longitudinal grooves is placed over ribs to establish a supporting relationship between the cover frame and the free ends of the ribs. The support provided by the cover frame to the ribs facilitates a subsequent cutting operation by a cutting tool on the ribs, thereby obviating potential damage to the ribs.
