Abstract (en)
A method for forming a corrugated structure from a fiber web comprises opening and carding a bale of fiber, forming the fiber web (40); alternatingly lapping the fiber web (40); and folding the fiber web at the alternating laps to form corrugations (21); spraying resin on the corrugated fiber web or melting fiber of low melting point incorporated in the fiber web and causing the resin or fiber of low melting point to bond the fiber web. The fiber web (40) can be sandwiched between a pair of outer webs with resin sprayed thereon and cured to assure the integrity of the sandwiched fiber web. <IMAGE>
