A weaving installation (400) comprises a loom (100) for making a woven texture by weaving between a plurality of threads, at least part of the plurality of threads being carbon threads (210, 211, 212, 213, 214, 215), the carbon threads each being individually stored on one bobbin of a plurality of carbon thread storage bobbins (220, 221, 222, 223, 224, 225) present upstream of the loom. The installation further comprises a plurality of pairs of first and second electrical contacts (301, 302; 303, 304; 305, 306; 307, 308; 309, 310; 311, 312) present between the storage bobbins (220, 221, 222, 223, 224, 225) and the loom (100). Each pair of first and second electrical contacts is present in the path of a carbon thread, the first and second contacts of each pair being intended to be in electrical contact with a given carbon thread. The contacts of each pair of first and second contacts are further connected to an open-circuit detection circuit (230).
