ABSTRACT:
A system and method for manufacturing pocketed compound nested coil springs includes inserting a compressed, preferably pocketed, smaller coil spring into a horizontally oriented larger coil spring either prior to compressing and inserting the outer coil spring into pocket material or after the larger coil spring has been pocketed thereby requiring the first spring to be inserted into and through an opening in the pocket material.
