A web-spreading shaft has a central rod with fixed modules aligned thereon. The modules are trapezoidal-shaped, in lateral view, and are aligned in fixed angular relationship along the rod. The latter is stressed axially and thus takes an arcuate shape, according to the angular relationship of the modules. Rotating cylindrical sleeves are aligned on the thus curved shaft. Means are provided for circulating a lubricating fluid between the rotating sleeves and the shaft.
