Abstract
Abstract The needle has an openable eye and is of use in a lacing stage of a tridimensional weaving of a composite reinforcement element, for driving out rigid rods and replacing them with loops of wire or thread. The needle has an axial aperture (13) at the end of the needle in the vicinity of the eye and the inner end of the aperture (13) is open and connected to the exterior through a passageway (14) which is oblique relative to the axis of the body of the needle (8) and laterally opens out through an orifice (15) in the vicinity of the eye (12), between the eye and the end of the needle.
