Abstract

Abstract A method for constructing a honeycomb structure, comprising employing parallel lines of fixed abutments alternating with lines of movable punches which are parallel to each other and parallel to the lines of abutment and have an active face facing the active faces of the fixed abutment which face them in an adjacent line and a face facing the gap between the two fixed abutments of the other adjacent line of abutments, the lines of each kind carrying on said facing faces at least one longitudinal component element of the structure, moving the lines of movable punches toward the lines of fixed abutments in a direction perpendicular to the lines of punches and abutments until said component elements are united in the surface common to the facing faces, interconnecting the component elements in said common surface and separating the structure obtained from the abutments and punches.
