Abstract (en)

Device comprising a first reed (A) which is subjected to the force applied by a variable number of turns of the reserve (RTM) and a second reed (B) which is subjected to the force applied by a constant number of turns which is equal to the depletion threshold of the reserve (RTm). The first and second reeds have the same elastic rigidity and are inserted in the base of the drum (12) of the feeder with one of their ends. Transducer means (30-31) are associated with each reed to measure the value of the resultants of the forces acting on the respective reeds, and processing means (UP) are provided to calculate the variation in the distance between the point where the resultant of the forces affecting the first reed (A) is applied and the insertion section of the first reed as the number of turns of the reserve (RT) varies and to emit a reserve residual measurement signal which is proportional to this distance. <IMAGE>
