Abstract
Curved profiles of thermoplastic material are prepd by (a) continuously extruding a profile with the desired section, (b) receiving the profile in the plastic state on a shaping device formed by a rotating metallic wheel, with the desired diameter, the surface of whose peripheral radial section fits exactly the interior shape of the profile (c) maintaining the profile against the wheel as it passes through a cooling zone, (d) allowing the profile to escape laterally from the shaping device, and (e) winding the profile helically around itself.
