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).

Weaving device for the production of a structure for a composite

A structure obtained by laying filaments on a convex axisymmetric surface to provide a hemispherical surface. The structure may include with a circular hole or a dead zone centered on an axis of the surface and may be formed by laying filaments along a geodesic path. The structure includes a first and second part, in which the first part includes the axis. The geodesic path formed by the filaments on the first part may be spaced a predetermined distance the opening or circular dead zone.

Structure with a convex axisymmetric surface

A machine for producing a reinforcement for a composite component. The machine includes a stand with a subframe having uprights with slideways for mounting a transverse bar on which is mounted a movable carriage. The carriage has a first movable arm extending in another direction and includes a second movable arm. The carriage is movable in a first direction, X, the first arm is movable in a second direction, Y, orthogonal to the first, and the second arm is movable transversely with respect to the plane defined by the bar and first arm in a third, Z, direction. Motors are provided to producing such movements. The second arm includes a thread-stitching tool which also constitutes a tool for laying down the thread and is mounted on a rotary support at the lower end of which is arranged the needle.
