Definitions

• the invention relates to a seal for ends of non-circular rod-shaped articles in the tobacco processing industry, which at least partially consists of rubber-elastic material and is removably seated on a carrier arranged on a test conveyor and through which test gas, preferably test air, can be introduced into the interior of the article.
• test gas preferably test air
• rubber-elastic material is understood to mean rubber (latex), but in particular also correspondingly elastic, wear-resistant plastic.
• rod-shaped articles of the tobacco processing industry includes rod-shaped smoking articles such as cigarettes, cigarillos or cigars with and without filters, which essentially consist of tobacco or another smokable material, and rod-shaped filter rods. It is known for testing cigarettes in to introduce this test air and to conclude from defects in the covering (holes, faulty ventilation zones) and / or filling from the resulting pneumatic values Usually supplied via at least one end of a cigarette sealing against the environment from rubber-elastic material and passed into the interior of the cigarette. At the other end of the cigarette, a seal for end sealing can also be provided, which, for. B. directs the test air or the pressure of the test air of a cigarette to a transmitter.
• the seals are attached to a test conveyor and are moved to their test positions by axial displacement and to their starting positions after the test has been carried out.
• a test conveyor test drum
• rubber-elastic seals for both ends of cigarettes is shown and described in detail in US Pat. No. 3,948,084.
• Their positions on the test conveyor correspond to the positions of the cigarettes during the test.
• the object on which the invention is based is to facilitate the assembly of non-circular seals for non-circular rod-shaped articles and to rule out incorrect assembly.
• the seal in the region of the carrier has a shape by which it can be applied to the carrier in a defined position relative to the test conveyor or the cigarettes located thereon.
• the invention is particularly advantageous in the case of seals for articles with an oval cross section, which are accommodated in receptacles of the seals which are also oval.
• the carrier has an area which is provided with a positioning profile for the correspondingly shaped seal.
• this area can be followed by a further clamping area with a smaller diameter in the direction of the test conveyor.
• the positioning profile of the carrier can be designed in a simple manner as a groove-shaped recess, that of the seal as a web accommodated therein, which therefore extends inwards from the inside of the seal.
• the positioning of a seal on its carrier is not limited to the example shown.
• the carrier can also be provided with a web and the seal with a groove-shaped recess.
• the carrier can be flattened in one place in a simple manner, while the inside of the seal has a correspondingly shaped bead.
• the seal according to the invention has the advantage that the mounting on the carrier is facilitated and can therefore be carried out quickly, and that a

• the test takes place during the passage of the cigarettes 3 through the test area 4.
• the seals 6 are moved axially away from the cigarettes 3 so that they can be released from the seals and can be conveyed away in their receptacles 2.
• FIG. 2 shows an oval seal end 8 at a short distance from the likewise oval receptacle 7 of a seal 6.
• the receptacle 7 of the seal 6 shows the opening 11 for the test air.
• the seal 6 is preferably also oval in the region of its jacket 14. It sits on a carrier 12 arranged on the test drum 1, which has a bore 13 for supplying or discharging test air. The test air is emitted from the test drum or flows towards it.
• Known control slots (not shown) in the test drum 1 are used to control the test air.
• the essentially cylindrical carrier 12, which has different diameters, has a groove-like recess 16 in a first region 15, the positioning region, into which an inwardly directed web 17 the seal 6 engages.
• the positioning area 15 in the direction of the test drum 1 is adjacent to a second area 18, in which the carrier 12 has a smaller diameter than in the positioning area 15 Clamping area 18 are pulled, where it "snaps" due to its elasticity and is thus held.
