ABSTRACT:
Disclosed is a method and an apparatus for conducting measurements on at least two physical properties, such as resistance to air permeation, diameter, weight, hardness and length, of cigarette filters. At least two measuring devices are used for conducting the measurement of designated properties, respectively. The method includes the steps of (a) feeding one filter plug simultaneously to each of the measuring devices, (b) simultaneously measuring the designated physical properties of the filter plugs by the measuring devices, respectively, (c) simultaneously removing the filter plugs from the respective measuring devices after measurement, (d) simultaneously feeding the removed filter plugs, except for the one removed from the last measuring device, to the subsequent measuring devices, while feeding a fresh filter plug to the first measuring device, (e) repeating the above-mentioned procedures, and (f) scanning the results of the measurements by the respective measuring devices in succession to store such result in a memory device.
