A method of making a honeycomb structure includes the step of intermittently slitting a sheet of material such that longitudinal slits are aligned in alternating staggered rows. Each staggered row has a lateral centerline spaced substantially uniformly from adjacent row centerlines. The longitudinal slits in each staggered row have substantially uniform lateral spaces between each slit. Another step is applying continuous stripes of adhesive laterally across a top side and a bottom side of the sheet such that each stripe is spaced apart longitudinally and centered on a row of slits. The stripes alternate between the top side and the bottom side. Still another step includes pleating the sheet such that pleats run longitudinally. Each pleat has a top fold and a bottom fold aligned with a longitudinal slit. Yet another step involves gathering the pleats together in a closed stack and compressing the stack to cause the stripes of adhesive to bond the pleats together at adhesive contact points. A final step is pulling the pleats laterally apart to generate hexagonal cells having interconnections at the adhesive contact points and openings between the adhesive contact points.

[ What is claimed is:] [5.] A honeycomb structure comprising a sheet of material having staggered rows of longitudinally oriented intermittent slits therein, said sheet of material also having lateral stripes of adhesive applied to a top side and a bottom side of said sheet, said adhesive stripes being spaced apart and alternating on said top side and said bottom side, said sheet being pleated to have longitudinal pleats, said pleats being compressed to connect said pleats to each other at said adhesive stripes, said honeycomb structure being generated by lateral pulling on said pleats to form interconnected cells, said cells being connected at said adhesive stripes by an adhesive bond and by a fold of said pleats, said fold providing sufficient strength to prevent said honeycomb structure from zippering open wherever said adhesive bond is inadequate.
