Abstract: A tubular liner for the lining of pipelines has an inner tubular film, a layer of fibrous material arranged on the inner tubular film, and an outer tubular film which is arranged on the outer side of the fibrous material and is impermeable to UV light. The tubular liner is distinguished in that the outer tubular film has a radially inward peripheral portion and a second peripheral portion bearing on the outer side of the first peripheral portion in an overlapping region. The peripheral portions are connected to one another by an adhesive tape which extends across the longitudinal direction of the tubular liner. A method is also provided for manufacturing such a tubular liner.

Abstract: A tubular liner for rehabilitating sewers has a reinforcing layer being expandable in the circumferential direction and formed of fiber rovings and impregnated with a curable reactive resin. The tubular liner has an outer tubular film which encloses the reinforcing layer and is formed of a material that can be expanded radially. A longitudinal pull strap is provided and absorbs the tensile forces acting on the tubular liner when the tubular liner is inserted into the sewer. The tubular film has a laminated nonwoven layer on the side facing the reinforcing layer. The longitudinal pull strap is located between the nonwoven layer and the reinforcing layer and is in immediate contact with the outer side of the reinforcing layer and the nonwoven layer. The longitudinal pull strap has a width of less than 50% of a length of the outer circumference of the reinforcing layer.

Abstract translation: 用于修复下水道的管状衬垫具有在圆周方向上可扩张的增强层，并由纤维粗纱形成并浸渍有可固化的反应性树脂。 管状衬垫具有包围增强层的外部管状膜，并且由能够径向膨胀的材料形成。 当管状衬垫插入下水道时，提供纵向拉带并吸收作用在管状衬垫上的张力。 管状膜在面向增强层的一侧具有层压非织造层。 纵向拉带位于非织造层和加强层之间，并且与加强层和非织造层的外侧立即接触。 纵拉带的宽度小于加强层的外周长度的50％。
