Pins (25) are temporarily implanted in a perforable mandrel (15) in the regions of evolution of its shape, and at the points where it is desired to change the direction of the wire, a continuous wire is stretched over said pins (25) to form crossed superimposed layers, and a continuous thread is introduced through them forming successive loops opened by means of a needle. The machine comprises a frame (1, 2, 3, 4), a rotary mandrel (15) on a horizontal axis (14), a vertical arm (12) having a removable working device (20) at its lower end and means (M1, M2, M3) for moving the arm (12) along three orthogonal axes X, Y, Z. |
