A porous structure is provided between a forming member and an underlying support structure so as to facilitate the drainage of liquid through the porous member when a web is supported on the porous member and columnar streams of liquid are directed at the web to form apertures in the web. The porous structure can include a plurality of spaced-apart, wire-like elements, a metal screen, thermoplastic netting, mesh, webbing, and the like. An improved apertured web made with the improved process employing such a porous structure has little or no lining or marking and has relatively few, if any, poorly formed apertures.
