PROCESS FOR MANUFACTURE OF THREE-DIMENSIONAL ROTATIONAL PARTS AND MACHINE FOR THE IMPLEMENTATION OF SUCH PROCESS Abstract of the Disclosure A machine for the manufacture of rotational parts in a three-dimensional material is disclosed. A mandrel provided with rows of barbs is rotatably carried by the machine, whereby superimposed layers of threads are successively deposited in the longitudinal and cir- cumferential corridors defined between the barbs. The machine additionally comprises a retractable member adap- ted to hold in place one extremity of a weft thread when the latter does not extend outside of the corresponding corridor, and a winding system which positions a holding thread in a circumferential corridor near the extremities of the weft threads to hold them in place when the retrac- table member has been retracted. - 1 -
