Process for measuring the forces between the working rolls of a roll stand, in which several extended load cells (51, 52, 53) placed between the working rolls (13, 14) are aligned in a plane passing through the axes of these rolls and distributed symmetrically with respect to the central plane of the stand, a pressing force is exerted on the balances by adjusting systems (27, 28), the value of the forces exerted simultaneously on each load cell is read and the values of the resulting pressing forces are deduced. Preferably, a device comprising two half-shell shaped pieces of malleable material such as copper is used, and this holds the load cells in alignment and serves as a bearing plate which can be cold-rolled. The process is applied to the adjustment of the gauges of a roll stand for flat products and to the precise determination of the yield curves.
