Apparatus for manufacturing pocketed coil springs having a retention mechanism for retaining first and second plies of material 25 and providing relative movement between the plies of material and an insertion mechanism 1a,1b between each actuation of the insertion mechanism. The insertion mechanism has at least a first insertion member 15a and a second insertion member 15b. Upon each actuation of the insertion mechanism, the first insertion member inserts a first coil spring 20a between the plies of material to a first location on a first side of an operative axis of the apparatus, and the second insertion member inserts a second coil (20b figure 5) spring between the plies of material to a second location on a second, opposite side of the operative axis of the apparatus. The first and second coil springs inserted by the first and second insertion members are arranged diagonally between the plies of material relative to the operative axis of the apparatus. Also disclosed is a method of manufacturing pocketed coil springs. |
