Abstract
Two parallel cigarette rods are guided in a twin cigarette rod making machine between two stationary ionization chambers of a density measuring apparatus. Two radiation sources are mounted on a carrier between the two rods for movement with the carrier between a first position in which the radiation issuing from the sources penetrates through the adjacent rods and into the respective ionization chambers, and a second position in which the radiation enters the respective chambers by way of passages in the guides for the respective rods.
