Abstract

The present invention combines the advantages of a prior art figure of 8 winding pattern with the traditional circular or oval pattern for packaging flexible cord to form what can be called a "figure of 80 pattern" which includes a generally S-shaped partial cord layer with the end of the S joining with a J-shaped portion arranged so that the straight portion of the J forms a continuation of the S and the curved portion of the J overlies the beginning of the S-shaped portion. This basic combination of S and J shapes designates only partial layers, the pattern can be repeated, that basic pattern can be connected to a plurality of oval turn layers or even a plurality of figure 8 turn layers as the user may elect. It is also possible to continue to merely alternate the basic layer form to provide a package having a high packaging density while permitting easy accommodation of fittings which are secured to the end of the cord.

Claims

1. In a packaging pattern for a flexible cord to be dispensed in an endwise direction and in a substantially tangle-free manner, a partially overlying cord turn configuration comprising:

a generally S shaped partial cord layer having an arcuate beginning portion, a central portion and an arcuate end portion; and

a J-shaped partial cord layer having a straight leg and an arcuate end, the straight leg end of the J-shaped partial cord layer being a continuation of the arcuate end portion of the S-shaped partial cord layer, and the aucute end of the J-shaped layer partial cord overlying the arcuate beginning portion of the S-shaped partial cord layer.

2. The high turn density package for dispensing flexible cord of claim 1 wherein a second J shaped partial cord layer is provided with the straight leg portion of the second J-shaped partial layer being an extension of the arcuate end of the first J-shaped portion and crossing over the central portion of the S-shaped partial layer, the arcuate end portion of the second J-shaped partial layer partially overlying the end portion of the S-shaped layer.

3. The package of claim 2 wherein the arcuate end portion of the second J-shaped partial layer extends to a second S-shaped partial layer whose orientation is reversed relative to the first S-shaped partial layer.

4. The package of claim 3 wherein the free end of the second S-shaped partial layer extends to the curved end portion of a reversed J-shaped partial layer.

5. The package of claim 1 wherein the J-shaped partial cord layer straight leg portion is arcuate thereby to provide a generally circular package configuration.

6. The package of claim 2 wherein the continuous flexible cord comprises a plurality of layers with the partial layer configuration repeated to form the complete package of continuous cord of the desired length.

7. The package of claims 1, 2, 3, 4, 5, or 6 wherein cord end fittings secured to the cord ends are nested within the spaces enclosed by the J-shaped portions of the layered package.

8. A continuous length of cord disposed in a configuration forming a high product density package comprising interleaved and repeated S-shaped cord portions and J-shaped cord portions arranged in partially overlying relation and in end to end continuing connection to provide a continuous length of cord in a package permitting substantially tangle-free dispensing.

9. The package of claim 8 wherein the continuous flexible cord package includes a frangible band surrounding the package to restrain the package during shipping and handling.

10. A portion of a packaging pattern for a continuous cord comprising

at least one generally "S" shaped layer having a beginning portion, a central portion and an end portion

the end portion continuing as a second layer portion extending to overlie the beginning portion of the S layer without crossing the central portion.

11. The portion of a packaging pattern for a continuous cord as set forth in claim 10 wherein said end portion continues from the overlying position to a crossover generally opposite to the direction of the central portion of the underlying S layer thereby to form an "X" appearance.

12. A method for forming a flexible cord package including a partially overlying cord turn configuration for dispensing the cord in an endwise direction and in a substantially tangle-free manner comprising the steps of

forming a generally S shaped partial cord layer having an arcuate beginning portion, a central portion and an arcuate end portion;

and

forming a J-shaped partial cord layer having a straight leg and an arcuate end, one end of the straight leg of the J-shaped partial cord layer being a continuation of the arcuate end portion of the S-shaped partial cord layer, and the arcute end of the J-shaped layer partial cord overlying the arcuate beginning portion of the S-shaped partial cord layer.

13. The method of claim 12 with the additional step of forming a second J-shaped partial layer as a continuation of the first J-shaped partial layer with the straight J portion crossing over the S-shaped layer portion.
