Septumization of cellular cores

A method and apparatus for producing a honeycomb structure in a continuous production process includes five process stations. At Stationsheets of deformable material are interleaved with a release ply to form a five layer sandwich. At Stationthe five layer sandwich is corrugated. At Stationthe two deformable sheets are separated and an adhesive is applied to one. At Stationthe two deformable sheets are connected to form a single layer honeycomb structure. And at Stationa plurality of single layer honeycomb structures are cut and stacked to form a honeycomb structure of a desired thickness.
