Liner conversion apparatus adapted to convert a flexible liner (2), including a layer of composite material (3), into a structural member within a duct (1) comprising a front portion (6) adapted to be inserted in the liner (2), a central portion (7) having heating means (8) on one side of the layer of composite material (3), and a rear portion (10) having consolidation means (11) for forcing the heated composite material (3) towards the duct (1), the central portion (7) adapted to force hot gas from the heating means (8) through the layer of composite material (3) to heat it, and provide an air gap (14) on the opposite side of the layer (3), and to have a further heating means (43), which substantially surrounds the heating means (8) and is on an opposite side of the composite layer (3). The further heating means (43) aids the distribution of heat through the layer (3), so that the side of the layer (3) remote from the heating means (8) is heated sufficiently.
La présente invention a trait à un appareil de conversion revêtement intérieur adapté à la conversion d'un revêtement intérieur souple (2), comportant une couche de matériau composite (3), dans un organe structurel au sein d'une canalisation (1) comprenant une portion avant (6) adaptée à être introduite dans l'enrobage (2), une portion centrale (7) ayant des moyens de chauffage (8) d'un côté de la couche de matériau composite (3), et une portion arrière (10) ayant des moyens de consolidation (11) pour contraindre le matériau composite chauffé (3) vers la canalisation (1), la portion centrale (7) adaptée à forcer du gaz chaud depuis les moyens de chauffage (8) à travers la couche de matériau composite (3) pour la chauffer, et assurer une lame d'air (14) sur la face opposée de la couche (3), et à inclure un moyen additionnel de chauffage (43) qui entoure les moyens de chauffage (8) et se trouve sur la face opposée de la couche composite (3) de sorte que la face de la couche (3) éloignée des moyens de chauffage (8) soit suffisamment chauffée.
