Abstract

LA PRESENTE INVENTION SE RAPPORTE A UNE METHODE POUR LA PRODUCTION D'UNE BANDE DE MATIERE (6) AYANT UNE SURFACE SUPERIEURE PLANE ET UNE STRUCTURE DE CAVITES PERFOREES (13 ;14) QUI FONT SAILLIE VERS L'EXTERIEUR A PARTIR DE LA SURFACE SUPERIEUR PLANE. CONFORMEMENT A L'INVENTION, UNE BANDE PLATE (6) DE MATIERE ELASTIQUEMENT DEFORMABLE EST MUNIE D'UNE STRUCTURE D'ENTAILLES MUTUELLEMENT SEPAREES A L'AIDE D'UN DISPOSITIF DE SOUDAGE PAR ULTRASONS (1), ENSUITE UNE CAVITE (13,14) EST FORMEE SUR UNE FACE DE CHAQUE ENTAILLE DANS LA BANDE. L'INVENTION SE RAPPORTE AUSSI A UN APPAREIL POUR METTRE EN OEUVRE LA METHODETHE PRESENT INVENTION RELATES TO A METHOD FOR THE PRODUCTION OF A WEB OF MATERIAL (6) HAVING A FLAT UPPER SURFACE AND A PERFORATED CAVITY STRUCTURE (13; 14) THAT EXTEND OUTSIDE OF THE FLAT UPPER SURFACE . IN ACCORDANCE WITH THE INVENTION, A FLAT BELT (6) OF ELASTICALLY DEFORMABLE MATERIAL IS PROVIDED WITH A STRUCTURE OF MUTUALLY SEPARATED THICKNESSES USING AN ULTRASONIC WELDING DEVICE (1), THEN A CAVITY (13,14 ) IS FORMED ON A SIDE OF EACH SIZE IN THE BAND. THE INVENTION ALSO RELATES TO AN APPARATUS FOR IMPLEMENTING THE METHOD
