Title
(EN) METHOD AND APPARATUS FOR MANUFACTURING DRY LINERS FOR PIPE REPAIR
(FR) PROCEDE ET APPAREIL PERMETTANT DE FABRIQUER DES CHEMISES SECHES POUR LA REPARATION DE TUYAU
Abstract
(EN) A method of manufacturing a liner for reinforcing a pipe includes providing a continuous first reinforcing fibers extending in a first direction, moving the first reinforcing fibers in a machine direction such that the first direction is parallel to the machine direction, providing sheets of a material having second reinforcing fibers extending in a second direction, placing the sheets onto the moving first reinforcing fibers such that the second direction is substantially perpendicular to the first direction, and folding the sheets into a closed shape.
(FR) La présente invention a trait à un procédé de fabrication d'une chemise permettant de renforcer un tuyau, qui consiste à utiliser des premières fibres de renfort continues s'étendant dans une première direction, à déplacer les premières fibres de renfort dans une direction de machine de telle sorte que la première direction soit parallèle à la direction de machine, à utiliser des feuilles d'un matériau ayant des secondes fibres de renfort s'étendant dans une seconde direction, à placer les feuilles sur les premières fibres de renfort mobiles de telle sorte que la seconde direction soit sensiblement perpendiculaire à la première direction, et à plier les feuilles afin d'obtenir une forme fermée.
