A vibrating flexible smoothing sheet or shroud disposed transversely of a direction of travel of a formed fiber panel including gypsum-cementitious slurry and embedded chopped fibers. The sheet is used to smooth the surface of the panel as it exits a fiber embedment station of a structural cementitious panel production line to remove grooves and other non-uniform surface imperfections to reduce the need for costly finishing after the panels are cured and cut to size. The flexible sheet is designed to float over the surface of the formed panel without tearing or otherwise damaging the surface of the heavily fiber reinforced surface layers of the panel. The vibrating sheet is pivotally mounted on the side dams of the web production line so it can float over the panel surface during use, but be raised off the line when not in use.
