ABSTRACT:
An integrated reticulate structure comprising interconnected criss-crossing arrays of continuous or discontinuous filaments. The arrays are located in different layers and are mutually connected by flexible, generally strip-shaped links. Each link is integral with a filament in one array and with a filament in another array.
A method of manufacturing an integrated reticulate structure commencing by extruding sheet in form of an adhesively connected assembly of one or more films and one or more arrays of ribs extending from at least one surface of each such film. To enable a formation of thin ribs and of a close spacing of the ribs there is preferably further coextruded a separating component between the ribs. The array(s) of ribs are subsequently intersected by a close system of parallel furrows which are formed through each film and through adjacent portions of the ribs, without interrupting the ribs; and if a separating component has been coextruded so as to fill the spaces between the ribs, this is removed, or the connections formed thereby are disrupted before or after the formation of the furrows.
