Patent

CA 2502828

The invention concerns a method for making flexible tube skirts comprising a step of making a cylindrical sleeve from a planar web including several plastic or metallic layers followed by a step whereby said cylindrical sleeve is cut out to the desired length to obtain said skirts. It comprises a step prior to the step of making the cylindrical sleeve, wherein the web is subjected to a plastic deformation resulting in its being thinned by at least 0.5 % or in producing a raised surface whereof the amplitude ranges at least between 1/30 and 5 times the thickness. The web is for instance passed through the air gap between two substantially parallel rolls. Typically, the rolls exert on the web a force ranging between 2.5 and 500 newtons per millimeter of web width.

Procédé de fabrication de jupes de tubes souples comprenant une étape de fabrication d'un manchon cylindrique à partir d'une bande plane comprenant une ou plusieurs couches plastiques ou métalliques suivie d'une étape où ledit manchon cylindrique est découpé à longueur voulue pour obtenir lesdites jupes. Il comprend une étape préalable à l'étape de fabrication du manchon cylindrique, dans laquelle on impose à la bande une déformation plastique se traduisant par un amincissement au moins égal à 0,5% ou par la création de relief dont l'amplitude est au moins comprise entre 1/30 et 5 fois l'épaisseur. La bande passe par exemple dans l'entrefer compris entre deux cylindres sensiblement parallèles. Typiquement, les cylindres exercent sur la bande un effort compris entre 2,5 et 500 newtons par millimètre de largeur de bande.
