ABSTRACT:
An elongated tube of convoluted fiber-containing sheet material, in which the fibers extend predominantly longitudinally and the convolutions are bonded together with a hardenable bonding material, which is flattened to provide at least a pair of opposed spaced parallel walls having longitudinally-extending grooves, beads, or indentations to provide enhanced support in terms of improved resistance to longitudinally-directed compressive loads, and enhanced cushioning in terms of improved resistance to transversely directed forces.
