ABSTRACT:
A testing apparatus for filter cigarettes or analogous rod-shaped articles has a drum-shaped conveyor with a smooth or fluted cylindrical surface and with radially inwardly extending suction slots which are connected to the intake of a fan. Each slot is disposed between two cradles which support the articles to be tested in such a way that the wrappers of the articles remain spaced apart from the periphery of the conveyor. The cradles engage the articles close to the respective ends of the articles and have small article-engaging surfaces to thus insure the detection of all or nearly all leaks during testing with a fluid medium which is introduced into the interior of a wrapper during travel past the testing station. The streams of air which flow into the slots of the conveyor hold the articles against ejection under the action of gravity and/or centrifugal force.
