An apparatus 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 has feed means for feeding thread from a source of thread, a rotary conduit () receiving the thread, thread-cutting device has a roller fixed with respect to the thread, and a moving cutter acting on the thread in collaboration with said roller so as, for each revolution of the rotary conduit, to release a length having a free end at the cutting means end. The apparatus also has a buffer positioned in the path of the free end so that, during the operation, the free end strikes the buffer before coming into contact with the receiving surface (S).

Device and method for guiding a thread

A device for laying reinforcement cords () of a tire. The device is formed of a first frame () comprising a motor-driven shaft () with an axis XX', the motor-driven shaft () supporting a reference form on which the blank () of the tire rests. The first frame () itself is mounted rotatably about an axis ZZ&#x2032; on a second frame () in such a manner that the axis ZZ&#x2032; has a point of intersection with the axis of rotation XX&#x2032; and belongs to the equatorial plane (E) of the blank () or of the reference form on which the blank rests. A third frame () is rigidly connected to the second frame (), the third frame () supporting an apparatus () for laying the lengths of cords () by projection of the lengths of cords directly into their final position on the receiving surface formed by the tire blank ().
