Abstract
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.
