<p>Hollow glass fibres laminated materials suffer, still nowadays, from the fault of containing water and other substances. The sealing processes used up to flow still show defects which are eliminated by the invention. The hollow glass fibre receives sealing walls during the spinning operation which takes place with a protection gas comprised of an aerosol wherein the material of the tight wall is in suspension. For this purpose, small hollow glass balls are used, of which the diameter corresponds to that of the fibres. The aerosol is directed by a cooled nozzle of the hollow fibre inner diameter, so that the current speed corresponds approximately to the spinning speed (about 1 to 1.5 m/s). </p> |
