Abstract
Device for manufacturing a reinforcement from a thread laid directly in its final place by casting lengths of the said thread onto a receiving surface, the said device comprising a feed means (200) for feeding the thread (1) from a source of thread (10), a rotary assembly comprising a rotary guide (2) of axis rr′ fixed to a hollow shaft (20, 205) constituting the axis of rotation (RR′) of the said guide (2) so that the outer radial end (21) of the said guide (2) is directed substantially radially with respect to the axis of rotation of the hollow shaft (RR′), the said guide receiving the thread (1) that comes from the said feed means via its central end (22) that is the opposite end to the said outer radial end (21), the said thread leaving via the said outer radial end (21), the said feed means controlling the linear speed at which the thread advances inside the said rotary guide (2), means (13, 131) for rotating the hollow shaft, and means (31) for cutting the thread, acting on the thread in such a way as to part off one length for each revolution of the said rotary guide (2). The said feed means comprises a motorized pulley (200), borne by the hollow shaft, the circumference of …
