ABSTRACT:
A corrugated core strip for use in the formation of honeycomb core panels is formed by a punch forming operation which simultaneously forms flanges at the edges of the core strip. The punching operation causes the flanges to be gathered at the troughs of the corrugations. The gathering is accommodated by forming grooves in the flanges which extend toward the flange on the opposite edge of the strip. The use of thicker core strip materials is facilitated, and the configuration both simplifies the manufacture of honeycomb core panels and improves the characteristics of the panels.
