ABSTRACT:
Filter cigarettes which are produced in a filter tipping machine are conveyed past several successive testing devices, each of which monitors different characteristics of the cigarettes, thereupon past a cigarette removing device, past a segregating device and on to a conveyor for transport of satisfactory cigarettes to a packing machine or into storage. When any one of the testing devices detects a defective or presumably defective cigarette, it generates a defect signal which is transported to the segregating device for expulsion of the respective cigarette from the path which leads to the conveyor. If the operator wishes, the defective or presumably defective cigarettes which are detected by a selected testing device can be conveyed only to and expelled by the removing device in response to the corresponding defect signals so that the removed cigarettes can be examined for the purpose of ascertaining the quality of testing operation which is carried out by the selected testing device. Alternatively, the removing device can be caused to expel a given number of satisfactory cigarettes for examination independently of the testing devices or for other purposes, or at least one pair of successive cigarettes for determination of the quality of imprints on cigarette paper.
