Abstract
This invention is concerned with cigarette making systems including a testing device for detecting bad quality cigarettes. Basically, the cigarette testing device is itself tested by deliberately making test cigarettes containing predetermined faults and checking whether the test cigarettes are detected by the testing device. The deliberate faults may be holes deliberately made in the cigarette wrappers. The holes may be made either on the cigarette paper web before it is wrapped around the filler in a continuous rod cigarette making machine, or the holes may be made in the wrappers of finished cigarettes.
