Abstract
The installation comprises support tooling having a shape that corresponds to that of the preform to be made and on which superposed layers of a two-dimensional fiber fabric can be draped; a needling head comprising a group of needles, a device for driving the needles lengthwise with reciprocating translation motion, and a bearing plate provided with perforations to pass the needles and suitable for being pressed against a layer draped over the support tooling; an arm carrying the needling head and possessing a plurality of degrees of freedom; and a control device for automatically controlling the displacement of the arm to move the needling head within the range of the arm along predetermined trajectories and with predetermined orientations.
