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.
