A device for manufacturing a reinforcement from a thread laid down directly in its final location by projecting lengths of the thread onto a receiving surface (S). The apparatus comprises an assembly comprising feed means ( 11 ) for feeding thread ( 1 ) from a source of thread, a rotary conduit ( 2 ) fixed to a shaft ( 20 ) constituting the axis of rotation of the conduit, so that the outer radial end ( 21 ) of the conduit is directed substantially radially with respect to the axis of rotation, the conduit receiving the thread ( 1 ) via its central end ( 22 ) which is the opposite end to the outer radial end ( 21 ) arriving from the feed means, the thread leaving via the outer radial end, the feed means controlling the linear rate of advance of the thread inside the rotary conduit, means for rotating the rotary conduit, thread-cutting means comprising an anvil ( 24 ) which is fixed with respect to the thread, and a moving cutter ( 31 ) acting on the thread in collaboration with said anvil ( 24 ) so as, for each revolution of the rotary conduit, to release a length ( 10 ) of which the end ( 10 b) is the end of the length at the cutting means end, wherein a buffer ( 25 ) is positioned in the path of the free end ( 10 b) so that, when the device is operating, the end strikes the buffer ( 25 ) before coming into contact with the receiving surface (S).
