Control of the positioning and continuity of threads in a loom

A weaving installation comprising a loom including a plurality of threads, at least part of the plurality of threads being carbon threads, the carbon threads each being individually stored on one bobbin of a plurality of carbon thread storage bobbins present upstream of the loom, wherein the weaving installation comprises a plurality of pairs of first and second electrical contacts present between the carbon thread storage bobbins and the loom, each pair of first and second electrical contacts being present in a path of one of the carbon threads, the first and second electrical contacts of each pair configured to be in electrical contact state with one of the carbon threads, wherein each contact of the plurality of pairs of first and second electrical contacts comprises a conductive element rotatable when in the electrical contact state with a carbon thread of the plurality of carbon threads, and the contacts of each pair of first and second contacts being further connected to an open-circuit detection circuit, wherein the first and second electrical contacts of each pair are used to loop the open-circuit detection circuit so that in case of absence or loss of the electrical contact state of one of the carbon threads with at least one of the first and second electrical contacts, the circuit becomes open.
