ABSTRACT:
A method for determining the operating parameters of a device for manufacturing a reinforcement from a thread (1) laid directly in its final position by projecting lengths of thread (10) onto a receiving surface (S). The device includes an assembly comprising a rotary conduit (2) of given length B and of longitudinal axis bb′ fixed to a shaft (20) of axis R constituting the axis of rotation of the conduit, so that the outer radial end of the conduit is directed substantially radially with respect to the axis of rotation, the conduit receiving the thread (1) via its central end, which is the opposite end to the outer radial end, from the feed means, the thread leaving via the outer radial end, feed means for feeding thread (1) from a source of thread, the feed means controlling the linear rate of advance of the thread inside the rotary conduit, means for rotating the conduit at a speed Ω about the axis R, the conduit running in a plane of rotation P forming an angle θ with the longitudinal direction of the receiving surface, and thread cutting means (24, 31), wherein the angle βcformed by the conduit and a direction of the plane P at the time that the length of thread is cut is determined in such a way that the initial contact between the length of thread and the receiving surface S is one third of the way from the rear of the length.
