Abstract
A process and apparatus for depositing simultaneously by winding on a support, several rovings of pre-impregnated fibers. The rovings are deposited simultaneously by winding on a rotating support. At least two rovings are brought into superposition near where they will be applied to the support, and the various rovings are subjected to different tensions depending on their position relative to the support. Specifically, the roving nearest the support is subjected to a greater tension than a roving farther from the support. Composite structures are thus produced.
