The invention relates to a lining element for the repair of a connection area between a main pipe and a branch pipe, comprising a layer of resin- absorbing material. In a first variant, at least three flexible, expandable lining parts are connected to each other by at least three connections to form the lining element. To manufacture such a lining element, the at least three flexible, expandable lining parts are provided and connected to each other by means of at least three connections to form the lining element. Furthermore, the invention relates to another lining element, comprising at least one lining part having a layer of resin-absorbing material, which has a tubular preform, and which is deformable by means of heat and/or forming to achieve a tubular final form. To manufacture such a lining element, at least one tubularly preformed lining part is provided having a layer of resin-absorbing material in a tubular preform, and then the tubularly preformed lining part is deformed by means of temperature and/or forming to form the final shape. |
