ABSTRACT:
A honeycomb part having a densified, frame-like outer periphery formed from compressed honeycomb cells which provide a relatively smooth, snag-free surface. The invention further includes the method of holding honeycomb stock material is a desired configuration and compressing an amount of the outer peripheral portion of the material beyond that configuration back to the configuration itself, thus providing the densified outer periphery of the honeycomb part. The apparatus for compressing and thereby densifying the honeycomb stock material includes a die having upper and lower knife edge gripping members and a cutting die which moves into cutting relationship to the honeycomb stock material to cut the material to the desired configuration. Then, the die, being stroked by a suitable press, continues to move and while doing so, presses the portion of the outer periphery of the stock material between the die and the knife edge grippers, compressing and thereby densifying the stock material.
