Claims
- 1. A string of pocketed coil springs comprising:a first and a second elongate fabric ply joined together by a longitudinal seam proximate a free edge of each of the plies; a plurality of transverse seams in the fabric; a plurality of pockets formed in the fabric, each of the pockets being between a pair of adjacent transverse seams; a plurality of springs each of which has opposed ends and is encased in one of the pockets and has longitudinal axis oriented generally perpendicular to the longitudinal seam; wherein the longitudinal seam is positioned on a side of the springs between the ends of the springs; and a two layer strip of fabric in contact with the pockets and formed between the free edge of each ply and the longitudinal seam; wherein the two layer strip is folded to overlap the pockets and the strip is attached to the pockets by the transverse seams.
- 2. The string of claim 1 wherein the longitudinal seam is positioned approximately midway between the ends of the springs.
- 3. The string of claim 1 wherein the fabric is thermally weldable and the seams are thermal welds.
- 4. The string of claim 1 wherein the plies are integrally joined together opposite from the respective free edges.
- 5. The string of claim 1 wherein the free edges of the first and second plies are juxtaposed together and on an opposite side of the longitudinal seam from the springs.
- 6. The string of claim 1 wherein each of the transverse seams is generally linear.
- 7. The string of claim 1 wherein each of the transverse seams is generally non-linear.
- 8. The string of claim 7 wherein each of the springs has a generally non-linear profile between the ends and the transverse seams generally conform to the non-linear profile of the springs.
- 9. The string of claim 7 wherein a portion of the transverse seam confronting the adjacent spring is concave shaped.
- 10. The string of claim 1 wherein each of the springs is partially compressed within the respective pocket.
- 11. A string of pocketed coil springs comprising:a first and a second elongate thermally weldable fabric ply joined together by a thermal weld longitudinal seam proximate a free edge of each of the plies, the plies being integrally joined together opposite from the respective free edges; a plurality of thermal weld transverse seams in the fabric; a plurality of pockets formed in the fabric, each of the pockets being between a pair of adjacent transverse seams; a plurality of springs each of which has opposed ends and is partially compressed and encased in one of the pockets and has a longitudinal axis oriented generally perpendicular to the longitudinal seam; wherein the longitudinal seam is positioned on a side of the springs approximately midway between the ends of the springs; wherein the free edges of the first and second plies are juxtaposed together and on an opposite side of the longitudinal seam from the springs; and a two layer strip of fabric in contact with the pockets and formed between the free edge of each ply and the longitudinal seam; wherein the two layer strip is folded to overlap the pockets and the strip is attached to the pockets by the transverse seams.
- 12. The string of claim 11 wherein each of the springs has a generally non-linear profile between the ends and the transverse seams generally conform to the non-linear profile of the springs.
- 13. The string of claim 12 wherein a portion of the transverse seam confronting the adjacent spring is concave shaped.
- 14. A string of pocketed coil springs comprising:a first and a second elongate fabric ply joined together by a longitudinal seam proximate a free edge of each of the plies; a plurality of transverse seams in the fabric; a plurality of pockets formed in the fabric, each of the pockets being between a pair of adjacent transverse seams; and a plurality of springs each of which has opposed ends and is encased in one of the pockets and has a longitudinal axis oriented generally perpendicular to the longitudinal seam; wherein each of the springs has a generally non-linear profile between the ends thereof and the transverse seams have a non-linear profile conforming to that of the springs.
- 15. The string of claim 14 wherein each of the springs are barrel shaped and a portion of the transverse seam confronting the adjacent spring is concave shaped.
