PCT No. PCT/GB94/02123 Sec. 371 Date May 23, 1996 Sec. 102(e) Date May 23, 1996 PCT Filed Sep. 29, 1994 PCT Pub. No. WO95/09947 PCT Pub. Date Apr. 13, 1995The invention is concerned with the production of filaments or fibers each of which carries a recognizable "signature" (encoding). These filaments or fibers are produced by taking a film (preferably a plastics film) applying a code directly onto the film across the effective width of the film and then dividing the film substantially at right angles to the code into longitudinal filaments, so that the encoding is then present in each of the filament in exactly the same "signature" as in the code applied to the film. |
