Abstract

1. Method for stretching a textile structure constituted of discontinuous fibers, arranged, for the most part at least, in parallel to the length of said structure, which structure can be either in fibersheet or in top or roving form, characterized by the fact the stretching is obtained by subjecting the moving fibrous structure to external pressures causing a simple shear effect which tends to make the fiber layers slide one with respect to the other, according to a speed gradient which results in the displacement, at different regularly staged speeds, of elementary fiber layers, on which normal forces are exerted to this effect, especially in the layers situated in the sliding area.
