Date Sep. 7, 1990.A spiral-shaped textile structure comprises warp yarns (1-17) across which are passed successive rows of weft yarns (A-S), whereby the warp yarns (1-17) are essentially arranged in spirals having the same axis, so that the textile structure forms superimposed annular spirals centered on an axis (O). According to the invention, each weft yarn (A-S) extends between a warp yarn, known as a starting yarn, and another warp yarn, known as a reference yarn, according to a radius of one of the textile structure's turns. Each warp yarn (1-17) serves, in at least one annular region of the textile structure, as a reference yarn for at least one weft yarn (A-S), the reference yarns being distributed so at to obtain a uniform textile structure in the annular region.
