ABSTRACT:
A cased coil spring producing apparatus comprises a coil spring producing mechanism for forming coil springs, a conveying mechanism including a conveyer for conveying the coil springs fed from the coil spring producing mechanism, a hardening-and-cooling mechanism for hardening the coil springs and cooling them, a sheet feeding mechanism for double folding a sheet and feeding it, a compression-and-insertion mechanism for compressing the coil springs and inserting them in the double folded sheet, a bonding mechanism for bonding the double folded sheet inserting therein the coil springs together, and a coil spring arraying mechanism for changing position of the coil springs inserted in the sheet. The conveyer of the conveying mechanism includes coil spring supporting members aligned in two or more rows rising upwardly therefrom. A sorting mechanism is provided for sortably distributing the coil springs fed from the coil spring producing mechanism to the coil spring supporting members.
