  • Weaving device for the production of a structure for a composite component
    Patent number: 6003564
    Abstract: Weaving device for producing a woven structure which is intended for the production of a composite component, including especially a component (5) for generating different speeds of movement for at least some of the warp yarns (FC). Component (5) includes a substantially plane profiled cam (5) capable of rotating about a longitudinal axis (X--X) and arranged so that the longitudinal axis (X--X) is approximately orthogonal to the direction (D) defined by the warp yarns (FC). The profile of the cam is defined by a variable transverse length (h) perpendicular to the longitudinal axis (X--X).
