Needling system for producing a textile preform

The method for determining a program of displacement and orientation of a needling head for making a textile preform by needling a textile strip on a support tooling, comprising at least:

• determining a set of triplets of coordinates of the points of passage of the needling head as a function of the positions of the fibers along the Z axis in the textile preform to be made, of its local geometry and of a predetermined minimum distance to be met between the needling head and the support tooling or the preform making it possible to avoid a collision with the latter, and
• determining the angular orientation of the needling head for each point of passage as a function of the angular orientation of the textile strip and of the Z fibers in the textile preform to be made,
• the method further comprising determining a local speed of displacement of the needling head as a function of the content of Z fibers in the associated area of the textile preform to be made and of a rotation of the support tooling.
