The present invention provides a stable material having enhanced extensibility and a method for making the same. A neckable material is fed in a first direction. The neckable material is subjected to incremental stretching in a direction perpendicular to the first direction. A tensioning force is applied to the neckable material to neck the material in a direction perpendicular to the first direction. The necked material is then subjected to mechanical stabilization to provide a stabilized extensible necked material. The stabilized extensible necked material is then passed between the peripheral surface of a cylinder which is driven in rotating motion and a device for pressing the stabilized extensible necked material against the peripheral surface of the cylinder. A retarding member retards the passage of the stabilized extensible necked material and directs the material away from the peripheral surface of the cylinder. The stabilized extensible necked material is easily extended in a direction parallel to the first direction and perpendicular to the first direction.
La présente invention concerne un matériau stable à extensibilité améliorée et son procédé de fabrication. On alimente un matériau compactable dans une première direction. On soumet ce matériau compactable à un étirement supplémentaire dans une direction perpendiculaire à la première direction. On applique une force de tension au matériau compactable, afin de compacter ce matériau dans une direction perpendiculaire à la première direction. On soumet ensuite le matériau compacté à une stabilisation mécanique afin d'obtenir un matériau compacté extensible stabilisé. On fait ensuite passer le matériau compacté extensible stabilisé entre la surface périphérique d'un cylindre entraîné en rotation et un dispositif permettant de presser le matériau compacté extensible stabilisé contre la surface périphérique du cylindre. Un élément retardateur retarde le passage du matériau compacté extensible stabilisé et éloigne ce matériau de la surface périphérique du cylindre. Le matériau compacté extensible stabilisé est facilement extensible dans une rotation parallèle et perpendiculaire à la première direction.
