ABSTRACT OF THE DISCLOSURE An extrusion crimping apparatus for inter- connecting a pair of extruded aluminum sections to an insert of thermanl break, wherein each of the pair of extruded aluminum sections includes a pair of flanges adapted to receive the insert therebetween. The apparatus comprises a pair of rollers mounted for receiving and pressing together the pair of extruded aluminum sections and the insert fed between opposing circumferential surfaces thereof. The surfaces of the rollers are of predetermined transverse width sufficient to overlie the flange portions and the insert on both sides such that the flanges clamp the insert therebetween. A plurality of protrusions project outwardly from the circumferential surfaces of the rollers for crimping the flanges to the insert thereby preventing longitudinal slippage between the extruded aluminum sections and the insert.
