Abstract
A cigarette filter attachment machine with a wrapper testing facility includes means for feeding pieces of tipping paper each of which is wrapped around associated tobacco and filter portions to join those portions to one another; means for testing the wrappers of the cigarettes for leaks; an upsetting device for momentarily upsetting the filter tipping operation to produce at least one cigarette with a deliberate leak in the joint between the tobacco and filter portions; and an ejection device arranged automatically to eject the deliberately faulty cigarette or cigarettes regardless of whether or not the wrapper tester detects the deliberately faulty cigarettes.
