ABSTRACT:
A tubular textile insert for strengthening material is made of a stack of successive layers of parallel and interlinked threads. More particularly, there is a first-direction layer defining a cylindrical shape and form by several parallel threads arranged in a spiral relative to the central axis of the cylindrical shape. A second cylindrical layer is also formed in a cylindrical shape by several parallel threads arranged in a spiral, but at a pitch in the opposite direction to the spiral pitch of the first layer. The cylindrical shape defines a plurality of generating lines that are angularly spaced apart from one another and extend generally parallel to the central axis of the cylindrical shape. Several binding threads are arranged parallel to the generating lines and link the threads of the first and second layers together without piercing or crossing those threads of the first and second layers.
