Abstract
A multiple fiber formation machine permits a simultaneous drawing of a plurality of N optical fibers and then a linear multifiber stranding. It comprises a first drawing assembly for a plurality of N fibers constituted by N regulatable preformed supports, a system of N fiber formation enclosures, a system for the simultaneous coating of N fibers, a plurality of N drawing or pulley capstans, and a fiber diameter measuring system. A second linear multifiber stranding assembly comprises a cable support supply system, positioning means for the N fibers from the first drawing assembly, a system of coating the support with its fibers and a cable reception drum.
Claims6
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.
