Zusammenfassung: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. By control of the pressure of the liquid a bead of liquid is maintained at each pore for wiping by the filament during passage with the pressure being insufficient to cause the resin to bleed from the plenum chamber via the pores during filament stoppage or absent the presence of filaments trained about the guide ring. One or more soft rubber scrapers wipe excess resin off the filaments and press the filaments against the mandrel. Alternatively, a number of atomizing nozzles spaced around the guide ring may apply the resin by production of a wet "fog" whose resin droplets quickly wet out the fibers without impinging on the fibers at high velocity.
