Pocket spring core - has parallel chains of pocketed springs with insert slits extending over half chain height

摘要

The pocket spring core has several parallel chains (2,3) of pocketed springs wherein each chain has a continuous row of springs which are connected together and enclosed by a cloth-like cover. In the area of the connecting seams (5), the chains have insert slits (6) which extend over half the chain height and are each open towards the same marginal edge. Each first number of chains (2) are set parallel with uniformly aligned slits spaced out relative to each other. A second number of chains (3) are set parallel to and spaced from each other at right angles to the first number of chains. The slits of the second chains are aligned uniformly relative to each other but opposite to the slits of the first number so that the first and second number of chains engage in each other with their slits. ADVANTAGE - It is only necessary to provide the slits in the area of the connecting seams of the chains for interconnection without welding etc.
