ABSTRACT:
A pocket coil spring producing apparatus includes a coil spring forming mechanism for forming coil springs, a hardening mechanism for hardening coil springs fed from the coil spring forming mechanism, a conveyor mechanism for cooling and conveying the hardened coil springs, and a compress inserting mechanism for compressing and inserting the coil springs conveyed by the conveyor mechanism into a two-fold sheet form of a sheet material. A sheet supplying mechanism folds the sheet material in two and feeds the same. A joining mechanism joins the two-fold form of the sheet material to have a row of substantially rectangular pouches into which are supplied respective of the compressed coil springs. A spring alignment mechanism aligns each compressed coil spring in a respective pouch in a lengthwise direction to return to a free, released state. A control mechanism controls the foregoing mechanisms.
