Patent ID: 7842148

Claim:
A method for determining 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), wherein 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 said conduit, so that the outer radial end ( 21 ) of said conduit is directed substantially radially with respect to the axis of rotation, said conduit receiving the thread ( 1 ) via its central end ( 22 ), which is the opposite end to said outer radial end ( 21 ), from said feed means, the thread leaving via said outer radial end; feed means ( 11 ) for feeding thread ( 1 ) from a source of thread, said feed means controlling the linear rate of advance of the thread inside said rotary conduit ( 2 ); means for rotating said conduit at a speed Ω about the axis R, said conduit running in a plane of rotation P; and thread cutting means ( 24 , 31 ), wherein the angle β c formed by the rotary conduit ( 2 ) and a direction (OX) 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 ( 10 ) and the receiving surface S is one third of the way from the rear of said length.
