Abstract (en)
[origin: WO2020193907A1] A weaving installation (400) comprises a loom (100 intended to produce a woven texture by weaving together a plurality of threads, at least some of the threads of the plurality of threads being carbon threads (210, 211, 212, 213, 214, 215), the carbon threads each being stored individually on one package of a plurality of carbon thread storage packages (220, 221, 222, 223, 224, 225) present upstream of the loom. The installation also 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 packages (220, 221, 222, 223, 224, 225) and the loom (100). Each pair of first and second electrical contacts is present on 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 also connected to an open-circuit detection circuit (230).
