Abstract: An apparatus for forming an array of extruded filaments combines an extrusion head having an opening, a movable body having an array of a plurality of apertures aligned with the opening for forming an array of filaments of material extruded through the opening and the apertures, and a support positioned for receiving the extruded array of filaments. The apertured body is moved continuously beneath the extrusion head opening so that a plurality of apertures are positioned simultaneously underneath the opening and in contact with the extruded material and an array of filaments is continuously formed. Relative motion of the support with respect to arrays of filaments forms a lattice structure of superimposed arrays.

Abstract: Edible products having a lattice structure are made by extruding an edible material into discrete arrays of discrete, essentially parallel, filaments, depositing a first array on a support, and superimposing a second array atop the first array so that the filaments of the first and second arrays are positioned at an angle.
