Abstract: A method for cutting a preform usable for production of a turbomachine part and including a weaving of a plurality of threads, the threads including single threads that are visually identifiable, along a cutting contour calculated based on a preform model in which the threads have a reference arrangement, the method including: taking an image of the preform; processing the image to determine a deviation in an arrangement of the threads which are visually identifiable relative to the reference layout; correcting the cutting contour according to the deviation; and cutting the preform along the corrected cutting contour.

Abstract: A warp yarn take-up system includes a clamping device for holding a plurality of layers of warp yarns, the clamping device being movable at least in a direction corresponding to the advance direction of the warp yarns. The clamping device includes a bottom clamp, a top clamp, and at least one intermediate clamping element present between the bottom clamp and the top clamp. The bottom clamp, the top clamp, and the at least one intermediate clamping element are held together by clamping.
