Abstract: A coil spring assembly machine for lacing coil springs together to form a coil spring assembly, which machine includes clamping jaws for clamping together portions of adjacent rows of coil springs in at least one of a top and bottom plane of the coil spring assembly, which clamping jaws include dies which cooperate with the end portions of the rows of coil springs to define a helical travel path for helical lacing wires as those lacing wires are moved through the helical travel path. The machine further includes a lacing wire forming and application mechanism for alternatively and selectively supplying lacing wires having two different physical characteristics to that helical travel path.

Abstract: A pocketed coil spring assembly for use in the manufacture of mattresses or cushions or the like comprising a plurality of longitudinally extending strips of integrally connected closed fabric pockets each containing at least one helically coiled wire compression spring having its axis disposed transversely of the strip, and wherein each of the strips contains a single band of interconnected springs formed from a single length of wire into a plurality of interconnected helical coil springs. In the preferred embodiment of the invention, each strip of spring containing pockets is spaced from each adjacent strip by a ply of resilient foam material, and each of the plies of resilient foam material are secured to the sidewalls of adjacent strips.
