METHOD AND APPARATUS FOR DRAWING IN OPTICAL FIBRES TWISTED LENGTHWISE, STARTING FROM SOFTENED GLASS |
| 摘要 |
The invention relates to a process making it possible to produce a drawn object having a chiralic structure. This production process consists of subjecting the object to torsion during its drawing and simultaneously to hardening making it possible to fix part of the thus obtained torsional stresses in the structure. |
