Claims
- 1. A method of making an expandable and contractible honeycomb panel including a plurality of parallel laterally adjacent rows of elongated tubular cells, comprising the steps of:
- providing a longitudinally extending length of a flat, foldable, creasable and drapable material, said material having a first surface and an opposed second surface;
- forming a pair of longitudinally extending creases in said material thereby defining two longitudinal margins of said material and a central web portion of the material between said creases;
- folding said longitudinal margins of said material over said central web portion along said creases;
- applying at least a first longitudinal glue line to the first surface of said material;
- applying a second longitudinal glue line and a third longitudinal glue line to said material, at least one of said second and third longitudinal glue lines being applied to the opposed second surface of said material; and
- stacking said folded material with the first, second and third longitudinal glue lines thereon such that said first longitudinal glue line secures one of said longitudinal margins of the material to the central web portion of the material and such that the second and third longitudinal glue lines secure the two marginal portions of said material to at least one adjacent length of said folded material.
- 2. The method of claim 1 wherein the step of folding said longitudinal margins over said central web portion includes folding said longitudinal margins over the same surface of said material.
- 3. The method of claims 1 wherein the step of folding said longitudinal margins over said central web portion includes folding one of said longitudinal margins over said first surface of said material and folding the other of said margins over said second surface of said material.
