发明名称 Roll packed bedding products
摘要 A roll of roll-packed bedding products is created by permanently securing spaced spring units between first and second webs of insulator material. The bedding products are compressed and wound into a roll for shipping. During shipment and handling, the spring units are maintained within the roll in a similar orientation spaced from one another by the first and second webs of insulator material until the roll is unrolled and the insulator web material cut between the spring units to create spring units having the insulator web material thereon.
