Abstract:
A method of packaging a plurality of spring units, each spring unit comprising a plurality of coil springs, each of said coil springs having a top turn and a bottom turn, said top turns of said coil springs defining a generally planar first surface and said bottom turns of said coil springs defining a generally planar second surface, said method comprising the steps of:providing first and second webs of insulator material, each of said webs of insulator material being adapted to separate said spring units from padding to be applied to said spring units, each of said webs of insulator material having a width including a pair of opposing side portions and a center portion; locating said first and second webs against said first and second surfaces, respectively, of said spring units; permanently securing said first and second webs to said spring units; and roll-packing said spring units and said webs of insulator material such that said spring units are at least partially compressed and upon unrolling, said webs of insulator material remain permanently connected to said spring units.
