An apparatus for assembling coil springs together into a matrix of coil springs. The apparatus has workholders with respective grippers that receive and hold portions of end turns of respective coil springs, and a loader supporting the workholders for moving the workholders through a motion that transfers the respective coil springs from a conveyor to the apparatus. The coil assembling apparatus has, for each coil, a die set having a fixed die and a movable die. The movable die is connected to a drive via linkage. The drive is operable to move the movable die through a motion that maintains a planar die face of the movable die substantially parallel to a planar die face of the stationary die. The coil assembling apparatus is also operable to automatically assemble two rows of coil springs into a row of coaxial coil springs.

Coil spring assembly machine

An innerspring structure for a mattress comprises a row of outer coils formed from a continuous piece of wire with the coils interconnected with interconnection segments and a row of inner coils similarly formed. The interconnection segments of the coils form coil heads for pairs of adjacent coils and each head includes a first linear portion disposed generally parallel to the row. The row of inner coils is positioned together and generally coaxially with the row of outer coils for forming reinforced coil units. A helical lacing structure winds around portions of the inner and outer coils to couple the coils together into reinforced coil units and the first linear portions of the coils are configured for being captured with at least approximately three loops of the helical lacing structure for forming a row of reinforced coil units.
