- ABSTRACT Method of forming a coil comprising a plurality of overlapping foil strips including the steps of forming a ribbon of the foil strips by bonding the strips together with an adhesive, coiling the ribbon, and then removing the adhesive.
- This invention relates generally to a method for handling material, and in particular to a method for forming coil packages of metal foil strips.
- Thin strips of metal foil have been used as a radar counter measure since World War II.
- chaff Thin strips of metal foil, referred to as chaff, have been used as a radar counter measure since World War II.
- aluminum foil cut into strips about half a wavelength long at the radar frequency was commonly used during World War II to give false echos when dispersed from aircraft.
- the strips are on the order of 50 mils wide and less than 1 mil thick. The length depends on the radar frequency, which according to the Encyclopedia Britannica may be 1 or 2 centimeters to a few meters.
- the packaging of the foil does not present much of a problem since the strips are relatively short. Strips less than centimeters in length are commonly packaged in bales with the foil strips in parallel axial alignment. However, longer strips, over centimeters in length for example, lack the axial rigidity or stiffness to be packaged in this manner.
- a novel chaff package has been devised for the longer chaff wherein the foil strips are coiled rather than baled. In this package, the strips are wound on the coil with each strip overlapping the succeeding strip. While the package is technically successful, hand packaging techniques have been too expensive to make the package economically feasible.
- a long foil ribbon comprising a plurality of foil strips of the desired dimensions is formed with the foil strips being lap bonded by a suitable adhesive.
- a desired coil is made with the foil ribbon, and then the adhesive is removed by means of a solvent, heat, or other suitable means, thus providing a coil package comprising a plurality of overlapping foil strips.
- the metal foil is supplied in the form of a relatively wide and long sheet.
- the sheet is cut into segments equal in length to the desired length of the foil strips. Thereafter, the strips are lap bonded into a continuous sheet by the adhesive.
- the reconstructed sheet is then cut into ribbons of the desired width, crimped if desired, and the ribbons are then coiled.
- the reconstructed sheet is coiled, and then a coil of the desired width is cut from the coiled sheet. Thereafter the adhesive is removed by solvent, heat or other suitable means.
- FIG. 11 is a perspective view of a sheet of metal foil prior to processing in accordance with this invention.
- FIG. 2 is a perspective view of segments of a metal foil sheet lap bonded together.
- FIG. 3 is a perspective view of a segmented metal foil ribbon being wound in a coil.
- a metal foil sheet 10 is shown in the typical form as received from a supplier.
- the metal foil aluminum or other suitable material, is on the order of 4 inches wide, several hundred feet long and 1 mil or less in thickness.
- the metal foil sheet is usually transmitted in a roll.
- the metal sheet is cut along the transverse dotted lines II to produce foil segments 12 of a length equal to the desired chaff length, usually of the order of 20 centimeters or longer.
- the metal foil sheet ll) is reconstructed by lapping and bonding the metal foil segments M2.
- a suitable soluble adhesive is provided between the overlapping portion 13 of the segments to provide the adhering bond.
- Such a suitable adhesive may be preferably soluble in an organic solvent such as benzene or toluene.
- a modified methoxylated polyvinyl alcohol which is soluble in water, can be used as the adhesive.
- the lap joint bond may be improved by the application of pressure and/or heat depending on the type of adhesive used.
- the sheet is cut along the longitudinal dotted lines 15 to produce ribbons 20.
- the ribbons are cut to have a width equal to the desired width of the chaff strips, typically 50 mils.
- Each ribbon 20 may then be crimped to improve its axial rigidity and resiliency and then wound to produce a coil 25 as shown in FIG. 3.
- the coil 25 has an inside and an outside diameter of the desired coil package.
- Coil 25 is then supported to prevent the uncoiling of the segments, and a solvent is applied to remove the adhesive which holds the segments together.
- Applicants have found that the soluble adhesive is best removed by submerging the coil in an agitated container filled with the solvent, or by passing the coil under a solvent spray. Since many of the materials may be beat and acid resistant, an adhesive can also be removed by the application of heat or by a suitable acid solution.
- a chaff coil package comprising a plurality of overlapping chaff strips without the need for time consuming manual operations or complex equipment.

Claims (7)
- 2. The method of forming a coil as defined by claim 1 wherein said adhesive is removed by a solvent.
- 3. The method of forming a coil as defined by claim 1 and further including the step of crimping the segmented ribbon before winding said ribbon.
- 4. The method of forming a coil containing a plurality of strips of material from a sheet of metal said material coMprising the steps of: cutting said sheet transversely into segments equal in length to the desired length of said strips, bonding said segments together with an adhesive for reconstructing said sheet, cutting the reconstructed sheet longitudinally into ribbons equal in width to the desired width of said strips, winding each of said ribbons for forming a coil of desired dimensions, and removing said adhesive from said coiled segmented ribbon.
- 5. The method of forming a coil as defined by claim 4 wherein said adhesive is removed by a solvent.
- 6. The method of forming a coil as defined by claim 4 wherein the bonding of said segments includes overlapping said segments after first applying said adhesive to the overlapping portion of at least one of said segments, and applying pressure to said overlapping portions.
- 7. The method of forming a coil as defined by claim 4 wherein the bonding of said segments includes applying a modified methoxylated polyvinyl alcohol to the edge portion of one segment, overlapping said edge portion with the edge portion of another segment, and applying heat and pressure to the overlapped edge portions.
- 8. The method of forming a coil as defined by claim 4 and further including the step of crimping each of said ribbons before winding said ribbons into a coil.
