Abstract
A method of detecting breakage or breakage of a continuous bead of fluid material, for example, a coating material, during the discharge thereof from an applicator nozzle, which comprises the steps of providing the applicator nozzle with a vibration sensor operable to detect vibrations occuring in the applicator nozzle and to generate a vibration signal, indicative of the detected vibration. The vibration signal undergoes a change in level when the vibrations are actually detected by the vibration sensor and the change in level of the vibration signal is compared with a reference amplitude level. Only when the amplitude level of the vibration signal exceeds the reference amplitude level, the change in amplitude level of the vibration signal provides an indication of the actual occurrence of the vibrations in the applicator nozzle.
