The length of the troughs 16 in the axial direction is somewhat greater than that of two cigarettes to be tested, the slot controls only indicated schematically. To are; of course, there is the possibility of seeing a pressure difference between the inside of the cigarette and being able to test each cigarette individually. To be able to re-open the troughs 16 made up of the troughs 16 and the test chambers (ie the eight test chambers formed by the belt strap 38 terminating in the belt 38) open again, is in the control slots 20 of the partial circuit of the Drum by the belt and 32 opposite end wall of the drum releases the troughs again. At this point, a cylindrical bore 46 removal device for faulty cigarettes can be provided in each trough 16, which removal device is flush with the closest provision, which is not shown in the drawing jump 26. In the bore 46 is axially 45 is; the ejection can, however, also be successfully fitted with a piston 48, the end face of which means that the suction air from the discharge drum 24 is simply drawn into the position shown in FIG. 2 rests against the cigarette head which is not in the vicinity for cigarettes recognized as defective. This is switched on, so that the defective cigarettes ge-way, the cigarettes lying in the trough opposite the deflection roller 40 fall under the device between the piston 48 and the opposite 50. The control means for the mutual end wall of the relevant trough 16 linking the functions are clamped from the relevant, so that the inside of the cigarette is known from the rest of the technology and therefore does not need to be pressure-insulated here in the part of the test chamber.
