Abstract
Abstract A seamless, wrinkle-free, cross-bias reinforced, porous nonwoven laminate made by shaping a web of cellulosic wadding longitudinally around a cylindrical mandrel, counter-orbiting second and third webs or thermoplastic adhesive-patterned drafted fibers around the mandrel to form opposite helices, heating the first web to laminate the webs near the edges of the first web, and severing the second and third webs along the length of the first web to produce the laminate.
