Abstract (en)
[origin: WO9203077A1] To produce a box-spring core with a plurality of parallel chains of boxed springs in which the neighbouring chains are jointed without any foreign material, it is proposed that the chains (2, 3) have insertion slots (6) in the region of the connecting seams (5) over half the height of the chains and open on the same edge, a first number of chains (2) with slots (6) in the same direction is arranged mutually parallel at a distance from one another, a second number of chains (3) mutually parallel and at a distance from one another is arranged at right angles to the first number of chains (2) but running in the opposite direction to the slots (6) in the first number and the first and second numbers of chains (2, 3) are arranged with interengaging slots (6) in lines and columns, whereby the distances formed between parallel rows are filled by components of the second number of chains (3) inserted in the gaps in the components of the first number of chains (3) so that the components of each subsequent line or column are arranged in mutually staggered array.
