DEFINITION

Classification: 428/593

(under subclass 544) Subject matter including a plurality of layers or components (a) wherein at least two of said layers or components include substantially parallel, narrow, elongated elements, such as strips, strands filaments, corrugations, grain fibers, grain crystals, etc., with such elements of one layer or component being arranged in defined angular relationship to those elements of the other, or (b) including discrete elements (e.g., tubular constituents) or component which form, or cooperate to form, cells, including filled cells, having longitudinal axes which are at an angle to the nonthickness surface of the stock-material.

(1) Note. Curvilinear or polygonal openings in an otherwise integral layer of material are not considered elongated elements for this subclass. See particularly subclasses 596+, below.

(2) Note. This subclass does not include mere plural layers of textile material without a specific description of the angular relationship between the fibers of the different layers or components.
