Abstract
A honeycomb structure formed of two continuous lengths of pleated materials secured together intermediate the pleats. Each length of pleated material defines one side of the honeycomb structure. The two continuous lengths are secured together by feeding them longitudinally of their length and toward each other. At the location where the two lengths meet, they are joined together intermediate their pleats.
Claims12
The method of fabricating an expandable honeycomb structure of a plurality of cells, one on top of the other, comprising the steps of:
- (a) continuously feeding a continuous length of a first material longitudinally of said length, said material having a first set of transverse creases spaced along the length thereof;
- (b) continuously feeding a continuous length of a second material longitudinally of said length and toward said first material, said second material having a first set of transverse creases spaced along the length thereof;
- and
- (c) joining the two materials together intermediate said first sets of creases.
