path of the double twist type in one of the two loops 9 10 equipped with means which facilitate the travel back of the twist on leaving the said loop the cord is subjected to an over twist by means of false twist applied by the over twister 13 in order to obtain an 34 inert 34 cord free from twist reaction and is then straightened in the straightener 14 and after passing over the capstan 12 is collected on the bobbin 11 as already indicated in the general description the process makes it possible to obtain a cord having the required properties namely improved compactness uniformity breaking load and flexibility these properties are achieved by the combination of the following main points of the process individual draw off of each wire to the correct length and imparting of final twist at the assembly stage by means of the assembling twister 3 positioning of the wires in the cord being formed facilitated by the drive rollers 8 which make it possible to lower and adjust the assembling tension and maintenance of the twist imparted by the twister 3 over the entire path by virtue of the travel back of twist imparted by the spindle as far as the outlet of the said twister 3 thus the wires are placed simultaneously and individually in the.
