Multiple fiber forming machine

Claim 1

A multiple fibre forming machine permitting a simultaneous drawing of a plurality of N optical fibres and then a linear multifibre stranding, wherein it successively comprises: (A) a first drawing assembly for a plurality of N fibres, said first assembly being constituted by: (a) N regulatable preform supports associated with controlled speed lowering means; (b) an assembly of N high temperature drawing enclosures, each receiving a preform and supplying a fibre; (c) a system for the simultaneous coating of N fibres constituted by N opening spinnerets or extrusion dyes supplied by a coating product and traversed by the fibres; (d) a plurality of N pulling capstans, each receiving a fibre and being controlled in rotation by an appropriate means; and (e) a system for measuring the diameter of the fibres controlling the fibre formation speed of said first assembly; and (B) a second linear multifibre stranding assembly constituted by: (f) a cable support supply system incorporating recesses for receiving at least one fibre; (g) means for positioning the N fibres from the first drawing assembly in the recesses of the support; (h) a system for coating the support with its fibres, said system supplying the cable; and (i) a cable reception drum.
