Abstract

Method for winding a fibre element onto a support, said fibre element comprising at least two longitudinal portions (P i) with different characteristics, comprising the steps of supplying the fibre element to the support and associating with each longitudinal portion a respective value of the winding pitch (p i) which is different from the values associated with the portions adjacent thereto; the winding pitch associated with each portion being modulated in accordance with a periodic function.
