The invention relates to a process for producing a flexible tube for lining
pipes, channels or the like, with an outer woven, layered or knitted glass-
fibre web, a voluminous glass-fibre product mat and a covering inner woven,
layered or knitted glass-fibre web, while the combined web thus formed is
shaped into a flexible tube and the combined web edges are bonded together, in
which the outer woven, layered or knitted glass-fibre web consists of a cut
fibre mat which is bonded to the voluminous glass-fibre product, which
consists of a needle felt, whereby the inner glass-fibre knitted web consists
of a cut fibre mat bonded with a voluminous glass-fibre product in the form of
a needle felt.
L'invention concerne un procédé permettant de produire un flexible destiné à garnir l'intérieur de canalisations, de canaux ou similaires, qui comprend une bande extérieure de tissu ou de textile tricoté, en filaments de fibres de verre, un mat volumineux de produit en fibres de verre et une bande intérieure de recouvrement en tissu ou en textile tricoté. La bande combinée ainsi obtenue est traitée de manière à se présenter sous forme de flexible et les bords de ladite bande combinée sont reliés les uns aux autres. La bande extérieure de tissu ou de textile en fibres de verre se compose d'un mat de fibres découpées, lié au produit en fibres de verre volumineux, et le mat volumineux de produit en fibres de verre est constitué de feutre aiguilleté. La bande intérieure en tissu ou en textile tricoté se compose d'un mat de fibres découpées, lié à un produit en fibres de verre volumineux se présentant sous forme de feutre aiguilleté.
