ABSTRACT:
There is provided an apparatus which can be incorporated into machines or production lines for the making of rod-shaped articles, such as filter cigarettes. The apparatus ascertains at least the diameters of longitudinally spaced-apart portions of an article, such as a continuous cigarette rod having equidistant portions of greater density, while the article advances lengthwise at a constant speed or at one of several different speeds. Accurate determination of the diameters of spaced-apart portions and, if necessary, a change of the diameter when it deviates from an optimum value, renders it possible to reduce the number of rejects and to turn out high-quality products, such as filter cigarettes wherein the mouthpiece is attached to the dense ends of the plain cigarettes; this ensures that the diameter of the dense end is identical with or sufficiently close to that of the filter mouthpiece so that the customary uniting band can secure the mouthpiece to the plain cigarette without leakage.
