Brief description of an object a structure from the chiralic drawing from a source of material softened, and the device implementing this process

摘要

The invention relates to a process for producing an object etire 1 having a structure the chiralic. / p & & p & this embodiment consists in subjecting a torsion 5 has the object 1 during its drawing 4, and simultaneously a hardening, which makes it possible to fix in the structure of a portion of the torsional stresses thus obtained. / p & & p & the invention applies in particular for the manufacture of optical fibers.
