摘要： The invention relates to a machine for winding a fibrous material on an impregnation mandrel, including an uptake mandrel for storing and dispensing the fibrous material (18), an impregnation mandrel (30) for receiving the fibrous material, a camera (46) for monitoring the passage of tracing warp yarns (50, 52, 54, 56, 58) and weft yarns (64), an image analysis module (47) for determining the positions of the intersections between sequential tracing warp yarns and tracing weft yarns, and comparing said determined positions with corresponding positions of intersections of reference tracing warp and weft yarns (66) and determining an off-centering value of the fibrous material for each of said intersections, electric motors (22, 34) for rotating the mandrels, and an electric motor control unit (42).

摘要： The invention relates to an automated method for the non-destructive testing of a woven preform (22), intended for the manufacture of a turbine engine part and including a plurality of first marker threads (30) intertwined with second marker threads (32), the first and second threads (30, 32) having light-reflecting properties that are different from those of the threads of the preform and being woven with the threads of the preform so as to form a surface grid on a given area of the preform (22). The method comprises determining, by means of a plurality of consecutive steps, the spatial coordinates of the intersections between the first and second marker threads (30, 32).
