Abstract:
1. 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 device comprising: feed means for feeding a thread from a source of thread; a rotary conduit fixed to a shaft constituting an axis of rotation of said rotary conduit, so that an outer radial end of said rotary conduit is directed substantially radially with respect to the axis of rotation, said rotary conduit receiving the thread via a central end which is opposite to said outer radial end arriving from the feed means, the thread leaving via said outer radial end, said feed means controlling a rate of advance of the thread inside said rotary conduit; means for rotating said rotary conduit; thread-cutting means comprising a roller which is fixed with respect to the thread, and a cutter mounted on a fixed arm acting on the thread in collaboration with said roller so as, for each revolution of said rotary conduit, to release a length of the thread, which has a free end at an end of the cutting means; and a buffer positioned in a path of the free end so that, when the device is operating, the length of the thread does not enter in contact with said buffer, except for said free end which strikes said buffer before coming into contact with the receiving surface (S).
