ABSTRACT:
An apparatus for making laminated dual and multiple arch corrugated structures including a first unit for making single-face corrugated members formed of a corrugated member and an attached liner and a second unit for combining one or more single-face corrugated structures into a double-face structure. The subject invention includes a novel mechanism for laminating one or more portions of the single-face or double-face corrugated structures and/or for impregnating one or more of the members of the such structures with an impregnating substance. The subject improvements also reside in a novel hold down roll construction to prevent wrinkling of the edge portions of web members used in the construction of corrugated panels.
