Extruded article and method of making the same

Method of making an extruded food article comprising

• (1) extruding at a first rate a first filament-forming, extrudable plastic mass which comprises a food or its precursor to form a plurality of spaced, straight continuous parallel elements;
• (2) extruding, at a second rate faster than said first extrusion rate and between adjacent spaced, continuous parallel elements, a second filament-forming extrudable plastic mass which comprises a food or its precursor to form an undulatable element which is thinner than it is wide to provide a cross-section with an aspct ratio of at least two, with the undulatable element being positioned with each opposite face of its wide dimension facing one of said continuous straight parallel elements, the surfaces of said plastic masses having a tacky first physical state which permits said surfaces to bond to one another at points of mutual contact and a second physical state in which subsequent bonding will no longer occur and in which latter state said elements have sufficient structural integrity to maintain their extruded bonded shape;
• (3) while the surfaces of said elements are sufficiently tacky to cause bonding therebetween at points of contact, causing said undulatable element to undulate in its thin dimension by permitting contact between a parallel element on one side of said undulatable element while maintaining the other adjacent parallel element in sufficiently close proximity to permit subsequent contact between it and the undulating undulatable element and to permit repetition of such undulation and subsequent contact, thereby providing a food article having an undulated element with apexes aligned on opposed sides wherein the apexes on one side of the undulated element are bonded to one of said parallel elements and the apexes on the other side of said undulated element are bonded to the other adjacent parallel element;
• and
• (4) changing or permitting the change of said plastic masses to said second physical state.
