Abstract (en)
[origin: US2003217413A1] A pocketed spring core includes a plurality of springs which are 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 is placed over and connected to the spring strands, and a second cover sheet is placed under the spring strands and connected thereto. 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.
