2 of 15 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 filament or fibre 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 assembly 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 annular guide ring assembly formed of two concentric annular rings, concentric about the mandrel partially defines a closed plenum chamber bearing a liquid resin under pressure. The resin is fed through a thin slit created by the space separating the two concentric rings 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 the slit for wiping by the filament during passage with the pressure being sufficient to cause the resin to bleed from the plenum chamber via the slit during filament training about the guide ring in a suitable quantity as to fully resin impregnate the filaments.
