MACHINE FOR WINDING A FIBROUS MATERIAL ENABLING ALIGNMENT AND OFF-CENTERING CONTROL BY IMAGE ANALYSIS

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).
