The invention relates to a method of and to an apparatus for ascertaining the transverse dimensions, such as diameters, of one or more rod-shaped articles, for example, continuous or finite-length cigarette rods and/or other rod-shaped smokers' products. When the method and/or the apparatus is utilized to ascertain the transverse dimensions of a single rod-shaped article, such as a continuous cigarette rod-which is stationary, which turns about its longitudinal axis and/or which is moved lengthwise, the apparatus can employ at least one radiation source which emits a beam of radiation against the stationary or moving article whereby the article intercepts a first portion of the beam and permits the remaining portion to impinge upon a device which evaluates the non-intercepted portion of the beam and generates signals denoting the diameter of the article. The apparatus also employs an arrangement, such as a motor and a belt-and-pulley device, for selectively altering the orientation of the beam and the article relative to each other; this enables the evaluating device to furnish signals which can be processed to indicate whether or not the article is round or out of round.

Method of and apparatus for ascertaining the transverse dimensions of rod-shaped articles

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.
