ABSTRACT:
A process and apparatus for fabricating expandable honeycomb materials disclosed. The continuous length of material is folded along opposite side portions thereof into a generally flat tubular form having upper lower layers. Adhesive is then applied along the length of the continuous material by first heating the material, applying the adhesive in a liquid state to the heated material, and then cooling the material to solidify the adhesive. The folded tubular material with solidified adhesive lines thereon is then wound about a rack in such a manner that the tubular material is deposited in a plurality of continuous layers one on another with the lines of adhesive being disposed between adjacent layers. The wound layers are then radially cut and placed in a vertically aligned stack while they are removed the rack. The vertically stacked layers are then heated to a temperature sufficient to activate the lines of adhesive and bond the layers together. Finally, the stacked tubular material is cooled to form a unitary stack of tubular, expandable honeycomb material. A device for performing the process as described above is also disclosed.
