<p>A device wherein a strip of three-dimensional fabric (38a), composed of two sheets (41a, 41b) of fabric connected by intermediate yarns (42), is impregnated with resin (84) and pressed between two impermeable strips (17a, 27a) on opposite faces of the three-dimensional fabric to form a stratified structure (77). The stratified structure is fed between two heated half molds (50, 55) presenting facing surfaces (52, 57b) diverging in the feed direction and presenting a suction system for gripping the strips (17a, 27a) to the surfaces (52, 57b) so that the stratified structure is hot-formed, and the yarns (42) of the three-dimensional fabric are straightened as the stratified structure is fed between the half molds (50, 55).</p> |
