ABSTRACT:
An article is provided comprising a plurality of straight spaced parallel extruded elements separated by a regularly undulated extruded element having an aspect ratio of at least about two, with undulations having opposed apexes on either side thereof, with apexes on one side of the undulated element being bonded to one of the parallel extruded elements and the apexes on the other side of the undulated element being bonded to the other of said parallel extruded elements. The article is formed by extruding a first filament-forming extrudable plastic mass to form a plurality of straight spaced continuous parallel elements, extruding (at a faster extrusion rate and between adjacent parallel elements) a second filament-forming extrudable plastic mass to form an undulatable element which is thinner than it is wide to provide a cross-section with an aspect ratio of at least about two, causing the undulatable element to undulate in its thin dimension and to bond to the straight spaced continuous parallel elements, and changing or permitting the change of the formed, extruded plastic mass so that subsequent bonding will no longer occur and so that the elements have sufficient structural integrity to maintain their extruded bonded shape.
