Abstract
After yarns or tows (10) have been pre-spread and placed side by side substantially in a common plane, their surface is swept by at least one jet of air (22) displaced transversely relative to the longitudinal direction of the yarns or tows so as to obtain a substantially unidirectional sheet (20) that is uniform.
