ABSTRACT:
Successive rod-shaped articles of the tobacco processing industry are conveyed transversely of their length along an arcuate path while advancing through a testing station wherein they are urged to impinge upon one or more sensors under the action of centrifugal force. The sensor or sensors transmit corresponding signals to one or more transducers which, in turn transmit signals to a processor wherein the signals are converted into signals denoting the actual weight of the tested articles. The apparatus can utilize piezoelectric transducers or other types of transducers, e.g., one or more extensometers.
