Abstract
The machine comprises a frame (1, 2, 3, 4), a rotary mandrel (15) mounted on a horizontal shaft (14), a vertical arm (12) having a detachable work device (20) at the lower end of the arm, and means (M1, M2, M3) for shifting the arm (12) along three orthogonal axes (X, Y, Z).
Claims5
A machine for manufacturing composite reinforcement elements woven in three dimensions from textile, mineral, synthetic or other fibers comprising:
- a frame;
- mounting means for mounting a disposable mandrel of foam or the like having externally the internal shape of the reinforcement element to be produced;
- rotation means for rotating said mounting means;
- a vertical arm carried by said frame above said mounting means and adjustable along three orthogonal axes;
- fixing means attached to said arm for detachably mounting work devices said fixing means including a foot member extending in the direction of said vertical arm, a motor fixed on said foot and a horizontal shaft supported by said foot and driven in rotation by said motor;
- implanting means for implanting rigid members in the mandrel, said implanting means being attachable to said fixing means;
- application means for applying on the surface of the mandrel successive layers of threads or fibers, the layers being superimposed and crossed in at least two directions;
- and interconnection means for interconnecting said layers by means of threads or fibers which extend perpendicularly through the layers.
