An apparatus for the continuous measurement of the draw resistance of a cigarette, comprising transducer which detects the pressure drop of a gas stream with constant volume, said gas stream being introduced at a format finger of a rod-producing machine into a rod of tobacco fibres. The measured value depending on the flow resistance of said rod is continuously determined and correlates very well with the usual static measurement of the draw resistance of cigarettes, i.e. of the tobacco rod of a cigarette, so that this continous draw resistance measurement during the cigarette production replaces not only the conventional random check but can also be used for controlling the production operation.

The filling force of compacted tobacco in the fillers of filter cigarettes which issue from a filter tripping machine is measured for the purpose of increasing the quantity of tobacco in the filters when the filling force decreases and visce versa. The filling force can be measured by pneumatically deforming successive increments of the wrappers of discrete cigarettes and ascertaining the extent of deformation or by mechanically deforming an entire stack of cigarettes and ascertaining the reduction of the combined volume of cigarettes. The quantity of tobacco can be regulated by removing a larger or smaller quantity of tobacco from a continuous stream which is thereby converted into the filler of a cigarette rod or by changing the speed of a conveyor in the distributor of the cigarette making machine so that the conveyor withdraws a larger or smaller quantity of tobacco per unit of time. The measurement of the filling force is carried out with a delay following severing of the cigarette rod so as to enable the filling force to rise to a value which is at least close to the final value. In addition to regulation of the quantity of tobacco in the fillers of cigarettes in response to ascertainment of the filling force, such quantity is further regulated when it deviates from a preselected value. The necessary measurements are carried out by a beta ray detector which is adjacent the path of the cigarette rod.

An inspection apparatus for a filter cigarette FT having a perforation line (6) in the outer circumferential surface of a filter (4) for introducing the outside air has a filter socket assembly (86) that is capable of receiving the filter (4) and includes a ring holder (124) defining in the inside an end chamber for surrounding the mouthpiece of the filter (4) and a surrounding chamber for surrounding the outer circumferential surface of the filter (4) including the perforation line (6), a guide pipe (102) for supplying a compressed fluid of the given pressure into the surrounding chamber of the ring holder (124), and a guide pipe (100) that outputs the pressure in the end chamber; and a pressure sensor for detecting the pressure outputted from the guide pipe (100) that outputs the pressure in the end chamber.

A smoking machine includes, for controlling the conditions in which each article to be smoked is smoked, only a servo-control device for controlling, to a reference value, the pressure difference between the suction end and the rest of the body of the cigarette. The support of each article is mounted for rotating so as to allow, for example, more accurate detection of the position of the incandescent zone by optical sensors and a processing circuit.

Pileups of tobacco particles at or between the inlet of the draping mechanism and the stream forming station in a cigarette maker are ascertained by a device which monitors the density of successive increments of the cigarette stream prior or subsequent to trimming or the extent of deformation of the finger which compresses the trimmed stream in the garniture of the cigarette maker. The monitoring device generates signals which are utilized to automatically interrupt the admission of tobacco particles into the stream forming channel.

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.
