ABSTRACT:
The structure is formed by superposed layers of fibrous reinforcing material, which layers are bound together by threads implanted through the layers by being pushed by a pressurized fluid into a tubular needle which is actuated with back and forth movements during which it penetrates through the superposed layers and is pulled out therefrom, leaving in a portion of binding thread, the next portion of binding thread being positioned after a relative displacement of the needle with respect to the structure along the surface thereof.
