1. A device for controlling a system for spraying a bonding composition onto mineral fibers, the spraying system comprising at least one ring, inside which the mineral fibers are intended to pass, and at least one spray nozzle arranged on the at least one ring and configured to spray the bonding composition onto the mineral fibers,
wherein the device comprises at least one flow sensor configured to measure a flow of a fluid of the sprayed bonding composition and at least one pressure sensor configured to measure a pressure of a fluid of the sprayed bonding composition,
wherein the device comprises a module configured to compare at least one pair formed by a value, measured by the at least one flow sensor, of the fluid flow and a value, measured by the at least one pressure sensor, of the fluid pressure, with at least one pair formed by a first previously defined reference value of a considered fluid flow, and by a second previously defined reference value of the considered fluid pressure, and
wherein the spraying system comprises at least a pump for feeding the fluid which is controlled into the device, so that a value of the flow of the fluid is constant.
