  • Patent number: 4494436
    Abstract: A braid wrapping wheel or carrier is mounted for rotation about its axis and concentrically surrounds a mandrel. The carrier bears rotatable spools of filaments or fiber material about its periphery. One end of each filament is affixed to the mandrel at a point axially displaced from the plane of carrier rotation and the filaments braid about the mandrel during carrier rotation and axial shifting of the mandrel along its axis. A guide ring contacting the filaments intermediate of the spools and the filament contact area on the mandrel define a path of movement for the inclined filaments. A fixedly mounted angular guide ring concentric about the mandrel partially defines a closed plenum chamber bearing a liquid resin under pressure. The resin is fed through fine pores within the ring wall over which the filaments are trained to resin impregnate the filaments.
