The invention relates to a device for testing cigarettes on the perfect condition of the paper wrapping by means of different air pressures within the filling and outside of the envelope.

When testing the paper wrapping of cigarettes or other air-impermeable, for example tubular wrappers For objects with air-permeable filling, it is important that the two ends of the cigarette are sealed so that air flow only occurs if there is a fault in the envelope can »For this purpose it is known, e.g. one Cigarette end, preferably the dog-piece end for filter cigarettes, to be sealed with a flat disc., The other end of the cigarette can be intestinal by means of this sealing disc be introduced into the test head of the device in the case of a filter cigarette, the end that is more sensitive to mechanical influences, z <, B. achieved by the

Opening is formed for receiving said other cigarette end as a cavity with a conical wall, is pressed against the pressed the end of the cigarette, "This arrangement has however the ffachteil that the abutting the conical wall in Ertifkopf end of BapierumhUllung can be easily damaged _o

The object of the invention is to design the seal in the erüfkopf of a cigarette testing device in such a way that the cigarette is held and the seal is achieved in such a way that the paper sleeve cannot be damaged _e

GeniSss of the invention is for receiving at least one end of a cigarette an elastically deformable sealing ring arranged in the Erüfkopf, the inside diameter of which is normally larger than the external acid knife of a cigarette to be tested, due to an axial one Draek, however, can be reduced so that the sealing ring has the Zi = garette holds and at the same time seals perfectly

The device is expediently designed in such a way that the axial pressure on the elastically deformable diaphragm ring is exerted by one leg of a toggle lever, the other leg of _{which is docked on an axle part s} on which the Erüfkopf rotates, while its rotation can be moved radially outwards =

This training has the advantage that Cigarette end inserted safely into the recess in the Ecüfkopf without being able to hit the sealing ring.,

(ο

that on the other hand, good centering and sealing is guaranteed with the greatest possible protection of the cigarette case. The axial pressure on the sight ring can easily be exerted with little construction effort.

An embodiment of the invention will now be described with reference to the accompanying drawings, namely show:

A crouch 9 on a non-rotatable axle part 10 moves the other via a pin H as the afrommel 2 continues to rotate Leg of the toggle lever δ radially outwards, so that the free leg presses the elastically deformable sealing ring axially, whereby its inner diameter is reduced and the seal causes v * ira.

The toggle lever 8 is pressed, the cigarette is also equally captured by the inner surface of the sealing ring 6, so that your delicate paper cover cannot be damaged. The other end of the cigarette is fed through the 3 sealed. Especially with filter cigarettes

such a seal on the Ifandstuck is completely sufficient

If an air flow arises when testing the cigarette by applying negative pressure to a duct 22 of a fault in the cigarette case, a piston 13 is moved to the left (in Pig, 1} and in a later turning stage of the drum clears the path for compressed air , through which the faulty cigarette is ausäbssen after the toggle lever 8 by the axial pressure of the elastic sealing ring 6 back into its
