Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
98 words
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.
Claim 2
Independent Claim
98 words
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.
Claim 3
Dependent Claim
50 words
The method according to claim 1 wherein: (a) said first and second materials each have a second set of transverse creases spaced along the length thereof in alternating fashion with the first set of creases; and (b) said two materials are joined together immediately adjacent said second sets of creases.
Claim 4
Dependent Claim
109 words
The method according to claim 2 wherein: (a) the first and second sets of creases are formed on opposite sides of said first and second materials to collapse said materials in accordian pleated fashion with said first and second sets of creases defining first and second sets of pleats, respectively; (b) said first and second materials are fed along first paths toward each other while at least in partially collapsed condition; (c) said first and second materials are progressively turned into and fed along a second, common path; and (d) said materials are connected together along said second sets of pleats as they are turned into said second path.
Claim 5
Dependent Claim
40 words
The method according to claim 3 wherein said first and second materials are: (a) turned into overlapping relationship at said second sets of pleats and immediately adjacent said second sets of creases; and (b) joined together in said overlapping relationship.
Claim 6
Dependent Claim
67 words
The method according to claim 3 further comprising: (a) feeding a piece of strip material sucessively into overlying relationship with each second set of pleats of the first and second materials adjacent the second set of creases as the materials are turned into said second path; and (b) adhering said strip material to each of said second set of pleats immediately adjacent said second set of creases.
Claim 7
Dependent Claim
30 words
The method according to claim 5 wherein: (a) said first and second materials are turned into said second path with the second sets of pleats laterally spaced from each other.
Claim 8
Independent Claim
29 words
The method according to any one of claims 3-6 wherein: (a) the first and second materials are connected together with the second sets of pleats facing in opposite directions.
Claim 9
Dependent Claim
35 words
The method according to claim 5 wherein: (a) said first and second materials are turned into said second path with the second sets of pleats in touching non-overlapping contact along the second set of creases.
Claim 10
Dependent Claim
27 words
The method according to claim 8 wherein: (a) the first and second materials are connected together with the second sets of pleats facing in the same direction.
Claim 11
Dependent Claim
42 words
The, method according to any one of claims 1-6, 8 and 9 wherein: (a) the first and second sets of creases on said first material are spaced from each other by a distance greater than the spacing thereof on said second material.
Claim 12
Dependent Claim
44 words
The method according to claim 10 wherein: (a) the first and second sets of creases in said second material are spaced from each other by one-half the distance any one cell extends between adjacent cells in the normal expanded condition of the honeycomb structure.
Claim 13
Dependent Claim
71 words
The method according to claim 11 wherein: (a) the first set of creases on the first material are formed to maintain the first material in angular configuration in the normal expanded condition of the honeycomb structure; and (b) the first set of creases on the second material are formed to fall out to orient the second material in a generally straight place in the normal expanded condition of the honeycomb structure.
