20080202691 | DEVICE FOR USING FIBERS WITH FLEXIBLE FIBER-ROUTING TUBES - A fiber application machine, for making components out of composite materials, that includes a system for displacing a fiber application head, fiber storage means, and fiber conveying means for conveying fibers from said storage means to the application head. The conveying means include flexible tubes connecting the storage means to the application head, each flexible tube being fitted with at least one longitudinal flexible blade of rectangular transverse cross-section, said flexible blade being placed substantially parallel to the plane of transport of the fiber received in the inner passage of the flexible tube. | 08-28-2008 |
20080216961 | APPLICATOR HEAD FOR FIBERS WITH SYSTEMS OF CUTTING AND LOCKING PARTICULAR FIBERS - A head for applying fibers in order to make components of composite materials, intended to be mounted at the end of a displacement system for applying to a surface a wide strip formed of a number of fibers. The head comprises an application roller, means for guiding fibers on said roller, cutting means including blades activated by activation systems for cutting the fibers upstream of the application roller, and blocking means including blocking studs activated by activation systems so as to block the fibers that have just been cut. The studs and the blades are activated by common activation systems which, for each fiber to be cut and blocked, displace a blade and a stud in order to cut and block the fiber. | 09-11-2008 |
20080216963 | APPLICATOR HEAD FOR FIBERS WITH PARTICULAR SYSTEMS FOR CUTTING FIBERS - The present invention relates to a head for applying fibers in order to make components of composite materials, intended to be mounted at the end of a displacement system for applying to a surface a wide strip formed of a number of fibers. The head comprises an application roller for applying fibers in the form of a strip, means for guiding fibers on said roller, and cutting means including blades activated by activation systems between a rest position and an active cutting position so as to cut the fibers upstream of the application roller. Said blades and associated activation systems are all placed on the side of the roller relative to said fibers. | 09-11-2008 |
20110011537 | Fiber application machine comprising a flexible compacting roller with a thermal regulation system - A fiber application machine for the production of parts made of composite materials comprising a compacting roller for applying on an application surface a band formed of at least a resin pre-impregnated flat fiber, and a heating system able to emit a heat radiation towards the band. The compacting roller comprises a rigid central tube provided with radial holes, and a cylinder made of an elastically deformable, flexible material, assembled on the central tube, and having a fluid communication assembly that brings the radial holes into fluid communication with the external surface of the cylinder. The machine includes a thermal regulation system that injects a thermal regulation fluid in the central tube internal passage. | 01-20-2011 |
20110011538 | Fiber application machine with compacting roller transparent to the radiation of the heating system - A fiber application machine for the production of parts made of composite materials comprising a compacting roller for applying on an application surface a band of at least a resin pre-impregnated flat fiber, and a heating system able to emit a heat radiation towards the band. The compacting roller comprises a cylinder made of an elastically deformable flexible material and substantially transparent to said heat radiation. | 01-20-2011 |
20110272126 | FIBER APPLICATION MACHINE PROVIDED WITH FLEXIBLE FIBER CONVEYING TUBES ARRANGED WITHIN A COLD SHEATH - 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. | 11-10-2011 |
20140083620 | FIBER APPLICATION HEAD INCLUDING A SEGMENTED COMPACTION ROLLER - A fiber application head for a fiber application machine for the production of parts made of composite materials, comprising a compacting roller, said compacting roller comprising several independent roller segments mounted side by side on an axial rod. Each roller segment comprises a tubular central portion through which said segment is mounted on the axial rod, a tubular peripheral portion having a cylindrical outer surface and one or more curved spring plate arranged between the outer surface ( | 03-27-2014 |
20140182787 | 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. | 07-03-2014 |
