Claims
- 1. A pocketed spring core, comprising a plurality of springs arranged sequentially in rows to form parallel adjoining spring strands, wherein each of the springs is supported in a pocket made of flexible material; a first cover sheet placed over and connected to the spring strands; and a second cover sheet placed under and connected to the spring strands, wherein at least one of the first and second cover sheets has predetermined regions which are opened in a direction transversely to a longitudinal extension of the spring strands by a plurality of slots to thereby form strips, wherein the slots are spaced at a distance which corresponds at least to a distance between two springs of a spring strand.
- 2. The pocketed spring core of claim 1, wherein the pocket is made of textile.
- 3. The pocketed spring core of claim 1, wherein the first and second cover sheets are glued to the spring strands.
- 4. The pocketed spring core of claim 1, wherein each of the strips, bounded by slots, has a dimension to cover a spring of a spring strand.
- 5. The pocketed spring core of claim 1, wherein several springs of at least one spring strand are covered by a single said strip.
- 6. The pocketed spring core of claim 1, wherein the slots in each of the first and second cover sheets extend from end to end.
- 7. A pocketed spring core, comprising a plurality of springs arranged sequentially in rows to form parallel adjoining spring strands, wherein each of the springs is supported in a pocket made of flexible material; a first cover sheet placed over and connected to the spring strands; and a second cover sheet placed under and connected to the spring strands, wherein at least one of the first and second cover sheets has predetermined regions which are opened in a direction transversely to a longitudinal extension of the spring strands by a plurality of slots to thereby form strips, wherein the slots in each of the first and second cover sheets extend partially across the cover sheets.
- 8. A pocketed spring core, comprising a plurality of springs arranged sequentially in rows to form parallel adjoining spring strands, wherein each of the springs is supported in a pocket made of flexible material; a first cover sheet placed over and connected to the spring strands; and a second cover sheet placed under and connected to the spring strands, wherein at least one of the first and second cover sheets has predetermined regions which are opened in a direction transversely to a longitudinal extension of the spring strands by a plurality of slots to thereby form strips, wherein the slots in each of the first and second cover sheets are so dimensioned as to leave an edge at the margin.
- 9. A pocketed spring core, comprising a plurality of springs arranged sequentially in rows to form parallel adjoining spring strands, wherein each of the springs is supported in a pocket made of flexible material; a first cover sheet placed over and connected to the spring strands; and a second cover sheet placed under and connected to the spring strands, wherein at least one of the first and second cover sheets has predetermined regions which are opened in a direction transversely to a longitudinal extension of the spring strands by a plurality of slots to thereby form strips, wherein the slots in each of the first and second cover sheets are so dimensioned as to leave a center web.
- 10. A pocketed spring core, comprising a plurality of springs arranged sequentially in rows to form parallel adjoining spring strands, wherein each of the springs is supported in a pocket made of flexible material; a first cover sheet placed over and connected to the spring strands; and a second cover sheet placed under and connected to the spring strands, wherein at least one of the first and second cover sheets has predetermined regions which are opened in a direction transversely to a longitudinal extension of the spring strands by a plurality of slots to thereby form strips, wherein the slots in each of the first and second cover sheets are so dimensioned as to leave an edge at the margin and a center web.
- 11. The pocketed spring core of claim 7, wherein the packet is made of textile.
- 12. The pocketed spring core of claim 7, wherein the first and second cover sheets are glued to the spring strands.
- 13. The pocketed spring core of claim 7, wherein each of the strips, bounded by slots, has a dimension to cover a spring of a spring strand.
- 14. The pocketed spring core of claim 7, wherein several springs of at least one spring strand are covered by a single said strip.
- 15. The pocketed spring core of claim 8, wherein the pocket is made of textile.
- 16. The pocketed spring core of claim 8, wherein the first and second cover sheets are glued to the spring strands.
- 17. The pocketed spring core of claim 8, wherein each of the strips, bounded by slots, has a dimension to cover a spring of a spring strand.
- 18. The pocketed spring core of claim 8, wherein several springs of at least one spring strand are covered by a single said strip.
- 19. The pocketed spring core of claim 9, wherein the pocket is made of textile.
- 20. The pocketed spring core of claim 9, wherein the first and second cover sheets are glued to the spring strands.
- 21. The pocketed spring core of claim 9, wherein each of the strips, bounded by slots, has a dimension to cover a spring of a spring strand.
- 22. The pocketed spring core of claim 9, wherein several springs of at least one spring strand are covered by a single said strip.
- 23. The pocketed spring core of claim 10, wherein the pocket is made of textile.
- 24. The pocketed spring core of claim 10, wherein the first and second cover sheets are glued to the spring strands.
- 25. The pocketed spring core of claim 10, wherein each of the strips, bounded by slots, has a dimension to cover a spring of a spring strand.
- 26. The pocketed spring core of claim 10, wherein several springs of at least one spring strand are covered by a single said strip.
