Abstract:

A method is provided for forming a corrugated structure from a fibrous web by first forming a fibrous web; alternatingly lapping the fibrous web; folding the fibrous web to form corrugations; brushing fibers from one corrugated peak to extend to an adjacent peak and bridge the gap therebetween; spraying resin on the corrugated fibrous web; heating the resin-sprayed corrugated fibrous web; or further sandwiching said fibrous web with a pair of outer webs with resin sprayed thereon and heating said sandwiched fibrous web. Another embodiment initially combines fibers of low melting point with regular fibers and heats the corrugated fibrous web after brushing, rather than spraying resin on the corrugated fibrous web.
