ABSTRACT:
Apparatus whereby a filament web impregnated with resin in the unpolymerized state is fed to a pole (1) at a predetermined angle (.alpha.) with respect to a plane perpendicular to this latter. The pole (1) is drawn in rotation about its axis (X-X') and the filament web is displaced along the pole from the bottom end to the top end thereof in a direction parallel to the axis of the pole while this latter is being driven in rotation. A plurality of parallel fiber slivers (8, 9, 10) spaced a distance apart are fed simultaneously to the pole (1) in a plurality of layers. The spacing between the slivers is progressively increased during displacement of the slivers between the bottom end and the top end of the pole and progressively decreased in the opposite direction. Similarly, the angle of the slivers to a plane perpendicular to that axis is progressively increased and decreased in the same directions that the spacing is increased and decreased. The apparatus is useful for forming a reinforcement wound structure of filaments on a cylindrical pole (1) of plastic material, the wound structure of filaments having a density which progressively decreases from the bottom end to the top end of the pole in each layer.
