Title (EN) METHOD FOR PRODUCING AN ALVEOLAR PANEL ELEMENT PARTICULARLY FOR COVERINGS, PACKAGINGS, SUPPORTING SURFACES, AND ALVEOLAR PANEL ELEMENT PRODUCED THEREBY
(FR) PROCEDE DE FABRICATION D’UN ELEMENT DE PANNEAU ALVEOLAIRE, NOTAMMENT POUR REVETEMENTS, EMBALLAGES, SURFACES PORTEUSES, ET ELEMENT DE PANNEAU ALVEOLAIRE AINSI FABRIQUE
Abstract:
(EN) A method for producing an alveolar panel element particularly for coverings, packagings, supporting surfaces and the like, comprising the steps of extruding a first layer (3) and a second layer (4) of thermoplastic material, shaping the first and second layers so as to provide, on each layer, a sheet-like element (20) with elements (21) that protrude on at least one face, and coupling the protruding elements of each layer in order to obtain an alveolar panel element.
(FR) L’invention concerne un procédé de fabrication d’un élément de panneau alvéolaire, notamment pour revêtements, emballages, surfaces porteuses, comprenant les étapes consistant à extruder une première couche (3) et une deuxième couche (4) de matière thermoplastique, à usiner les première et deuxième couches de façon à former sur chacune d’elles un élément de type feuille (20) comportant des éléments (21) faisant saillie sur au moins une face, et à accoupler les éléments saillants de chaque couche pour obtenir un élément de panneau alvéolaire.
