Abstract: A machine, for the construction of a braid (11), that includes a set of identical multiindented wheels (2), which are mounted on a fixed support (1) and driven in rotation to cause the circulation of spindles (6) carrying spools (7) of braiding threads (8). The multiindented wheels are disposed in parallel and equidistant lines (L—L). In the set of multiindented wheels: the multindented wheels (2) belonging to a line are spaced from one another, so that two consecutive multiindented wheels belonging to one and the same line cannot cooperate directly with one another; and a multiindented wheel (2) belonging to one line is disposed between two multiindented wheels belonging to an adjacent line and cooperates with the two multiindented wheels, In the spaces between the consecutive multiindented wheels of a line, there are provided passages (3) for the longitudinal elongate elements (9) of the braided tubular structure.

Abstract: Braided tubular structure (11) including longitudinal elongate elements (9) distributed on a plurality of collars coaxial with the structure and braiding threads (8) forming two grids of directions oblique in relation to the longitudinal elongate elements and interlaced with the longitudinal elongate elements. The braiding threads following paths which cause them pass between the longitudinal elongate elements. In the tubular structure, the braiding threads (8) of each one of the grids form an assembly of superposed layers in which the braiding threads (8) are parallel from one layer to the next.

Abstract: The manufacture of a fibrous structure (1) for a composite material part. At least one portion (3) of the fibrous structure (1) is obtained by at least partial machining of a fibrous blank stiffened by freezing a liquid impregnating the blank.

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).
