Honeycomb structure with band-joined folded material

Abstract From the Canadian patent

A honeycomb structure formed of a continuous length of foldable material having its longitudinal edges folded over one side of the material and secured to a separate strip material. The strip material is also secured to the adjacent cell of the structure. In forming the honeycomb structure, a continuous length of material is fed longitudinally as the edges thereof are folded over onto one side. The strip material is then fed over the folded material and the edges of the strip material are secured to the folded edges of the continuous length of material. The combined structure is then directed into a loop whereby the center portion of the strip material comes into engagement with the other …
