A mass of flowable food material is extruded to form a moving, continuous, flexible extrudate ribbon that is cured to form a continuous, semi-rigid ribbon. During curing, the ribbon is fed between a pair of pull rollers that pull the ribbon at a rate of speed that is faster than the extrusion rate of the ribbon, to thereby stretch the ribbon while being cured into semi-rigidity. The semi-rigid ribbon then is fed between a cutter roller and an opposing backup roller, the cutter roller including outwardly projecting, transversely mounted blades with edges that bias against an outer support surface of the backup roller during cutting. The opposing cutter and backup rollers rotate at substantially the same speed as the pull rollers to cut the semi-rigid ribbon with cuts that are substantially perpendicular to the direction of ribbon travel, thereby forming individual food pieces having substantially planar cut faces.
