Fiber application machine including flexible fibre-conveying tubes provided with flexible blades
The present invention relates to a fiber application machine, for making components out of composite materials, comprising a fiber application head, fiber storing means, and means for conveying the fibers from said storage means to the application head. The conveying means comprises first flexible tubes, that receive one fiber into its internal passage. Each flexible tube is provided with at least one longitudinal flexible blade of rectangular cross section. Each first flexible tube and its associated flexible blade are placed in a second flexible tube so that the second flexible tube holds the flexible blade substantially against the first flexible tube, while allowing relative longitudinal movement of the flexible blade in relation to the first flexible tube.
A fiber application machine comprising a fiber application head, a displacing system to displace said fiber application head, a fiber storage, and a fiber conveyor to convey the fibers from the fiber storage to the application head. The machine further comprises a safety system comprising at least one perimeter barrier defining a safety zone wherein the displacing system carrying the application head is placed, the fiber storage being arranged outside of said safety zone.
A fiber application machine for the production of composite material parts, comprising a system for displacing a fiber application head, a fiber storage, and a fiber conveyor for conveying the fibers from the fiber storage to the application head, the fiber conveyor being placed in the internal passage of at least one flexible tubular sheath, the machine further comprising a cooling system adapted to inject cold gas in the internal passage of the sheath.
