Claims
- 1. A method for fabricating an expandable honeycomb structure, comprising:
feeding at least first, second and third webs in a downstream direction; applying lines of adhesive to the first, second or third webs; forming the third web into individual strips before or after the adhesive has been applied; bringing the first and second webs into juxtaposition and alignment such that a pair of spaced lines of adhesive are aligned with each strip with each line of the pair being exposed to a different side of each strip and with the strips sandwiched between the first and second webs; and applying heat or pressure to cause the adhesive lines to adhere the individual strips to both the first and second webs to form a unitary structure.
- 2. A method for fabricating an expandable honeycomb structure, comprising:
feeding first, second and third elongated webs of material in a downstream direction; applying spacer longitudionally extending beads of adhesive to the first and second webs; positioning the third web between the first and second webs and cutting the third web longitudinally into a plurality of side-by-side strips; and passing the first and second webs and the side-by-side strips between heated rollers for impressing the materials together while activating the adhesive to bond the strips between the first and second webs.
- 3. The method of claim 2, wherein the beads of adhesive applied to the first and second webs are spaced from each other a distance approximately equal to the width of said strips and the beads on the first web are positioned approximately mid-way between the beads on the second web and that the beads are enganged with opposite faces of the strips at locations adjacent to the side edges of the strips.
- 4. The method of claim 3, wherein said first and second webs are transparent and said third web is opaque.
- 5. A method for fabricating an expandable honeycomb structure, comprising:
feeding first and second elongated webs of material in a downstream direction; applying elongated beads of an adhesive material to said strips adjacent to the side edges of the strips with only a single bead on one face of a strip and with the bead on one face being adjacent to an opposite side edge from the bead on the opposite face; passing the first and second webs with the strips therebetween between a pair of rollers to bond the strips to the first and second webs.
- 6. The method of claim 5, further including the step of providing said strips of material in independent rolls.
- 7. The method of claim 5, wherein said strips of material are supported by a belt conveyor in between said first and second webs.
- 8. The method of claim 5, wherein said strips are opaque and said webs are transparent.
- 9. The method of claim 5, wherein said rollers are heated.
- 10. An apparatus for fabricating an expandable honeycomb structure, comprising:
a supply roll of a first web of material; a supply roll of a second web of material; feeding means for advancing the first and second web materials in a downstream direction; a supply roll of a third web material; feeding means for advancing the third web material in a downstream direction between said first and second webs; a cutter for cutting said third web material into elongated strips extending in the downstream direction; an adhesive applicator for applying beads of adhesive to said first, second, or third webs; and compressive means for bringing the first and second webs into juxtaposition and alignment such that a pair if spaced lines of adhesive are aligned with each strip with each line of the pair being exposed the different face of each strip and with the strips sandwiched between the first and second weeks and secured thereto.
- 11. The apparatus of claim 10, wherein said first and second webs are transparent and said third web is opaque.
