摘要： The wrappers of filter cigarettes are tested during transport in the peripheral flutes of a drum-shaped conveyor through a testing station where at least one end of the wrapper receives air at a previously stabilized pressure. The stabilized pressure is monitored by an electropneumatic transducer which further monitors the pressure differential between the interior and the exterior of the wrapper at the testing station and transmits appropriate signals to a computer which generates test signals by forming a quotient from the signals denoting the pressure differential and the signals denoting the stabilized pressure. The computer can further process and evaluate signals denoting a selected reference pressure as well as the pressure of air which is used to reduce the likelihood of leakage of air from the interior of the wrapper at the testing station.

摘要： The diameter of a continuous filter rod is monitored in a tubular nozzle through which successive increments of the rod are conveyed axially and which directs against the external surface of the tubular envelope of the rod a narrow annular stream of compressed air at a pressure which does not result in deformation of the envelope. The thus admitted air is permitted to escape into the atmosphere only by way of two narrow passages which flank the region of contact between the air stream and the envelope. A flow meter indirectly monitors the rate of flow of air through such passages and generates signals which are indicative of the diameters of successive increments of the envelope. The pressure of the air stream which impinges upon the envelope is constant. The permeability of the material of the envelope can be ascertained by a discrete testing unit, and the results of such test are processed with the results of monitoring of the diameter by a computer which transmits signals serving to adjust the machine, to actuate an alarm or to arrest the machine.
摘要翻译：在管状喷嘴中监测连续过滤杆的直径，杆的连续增量通过该管状喷嘴轴向传送，并且其以不受压力的压力指向杆的管状外壳的外表面的窄的压缩空气流导致信封的变形。这样允许的空气仅允许通过在空气流和信封之间的接触区域侧面的两个窄通道逸出到大气中。流量计间接监测通过这些通道的空气流量，并产生指示信封的连续增量的直径的信号。撞击信封的气流的压力是恒定的。可以通过离散的测试单元来确定信封的材料的渗透性，并且通过传送用于调节机器的信号的计算机监视直径的结果来处理这种测试的结果，以致动警报或逮捕机器。

摘要： A stream of tobacco fibers is formed in a channel by showering the fibers against the underside of the lower reach of a foraminous belt conveyor which cooperates with a suction chamber to attract the fibers and to advance the stream past a trimming station where the surplus of fibers is removed by an adjustable equalizing device. The density of the stream is monitored upstream of the trimming station, and the thus obtained signals which are indicative of the density of successive increments of the stream are used to adjust the equalizing device so that the density of the trimmed stream is maintained within a desired range. Monitoring of density upstream of the trimming station ensures that the position of the equalizing device is properly adjusted not later than when the monitored increments of the stream reach the trimming station.

摘要： A stream of agglomerated short, medium long and long tobacco shreds as well as clumps or lumps of shreds and elongated fragments of tobacco ribs is fed onto a vibrating sieve which permits the short and medium long shreds to descend onto a first vibrating conveyor and causes the long shreds, clumps and fragments of ribs to advance onto a second vibrating conveyor whose upper surface has longitudinally extending grooves for the fragments. The long shreds and clumps are removed from the conveyor by a rotating carded drum which breaks up the clumps and delivers the long shreds and the shreds of the broken up clumps into a duct. The latter also receives short and medium long shreds from the first conveyor which is mounted below the second conveyor. The latter has openings for short and medium long shreds which might have been entrained by the long shreds, clumps and fragments of ribs. A metering device regulates the rate of admission of long shreds and shreds of the broken-up clumps into the duct. The rate of admission of agglomerated shreds and sieve receives predetermined quantities of unsifted material per unit of time.

摘要： Apparatus for making one or more rod-like fillers of shredded tobacco for use in the making of cigarettes or the like employs one or two pneumatic conveyors having endless foraminous belts trained over pulleys and including elongated stretches below communicating parts of a common suction chamber. A shower of intermixed tobacco shreds and smaller particles including tobacco dust and coarser particles is directed against the under sides of the elongated stretches. The shreds are attracted to and advance with the respective belts to form streams which are ready to be trimmed and thereupon draped into cigarette paper or the like. At least some smaller particles penetrate through the respective belts into the corresponding parts of the suction chamber. The contents of the suction chamber are evacuated by suction and are returned to the undersides of the elongated stretches of the belts for classification. At least some coarser particles advance with the belts and are incorporated into the respective streams of tobacco shreds. The smaller particles enter the respective parts of the suction chamber and are pneumatically conveyed to the main dedusting unit of the cigarette making plant.

摘要： One or more streams of tobacco in a rod making machine are tested by several density monitoring units one of which employs a source of nuclear radiation and at least one other of which employs a source of optical radiation. The resulting density signals are evaluated and converted into signals which are devoid of the influence of changes of color and/or blend of fibrous material in the stream or streams and are used for segregation of defective rod-shaped articles and/or for controlled removal of surplus from the stream or streams.

摘要： A rod-like filler for the making of a cigarette rod is obtained by showering particles of tobacco onto a foraminous belt conveyor which is located in front of a suction chamber and is flanked by two additional foraminous belt conveyors or by two stationary sidewalls so that the particles form a thin layer having a substantially U-shaped cross-sectional outline with a centrally located web and two legs. The legs are thereupon moved toward each other to convert the layer into a tube having a relatively soft core or a centrally located channel which is devoid of tobacco, and the filler is then draped into a web of cigarette paper and simultaneously densified to reduce its cross section to that of a cigarette before the resulting cigarette rod is subdivided into discrete cigarettes of desired length. The thickness of the layer is a fraction of its width. The sidewalls and/or a mandrel which keeps the center of the filler free of tobacco particles can admit into the layer hot air, moisture-laden air and/or volatile flavoring agents prior to conversion of the layer into a rod-like filler.

摘要： The wrappers of filter cigarettes wherein wrapper portions surrounding the filter mouthpieces have holes for admission of atmospheric air into the column of tobacco smoke are tested during sidewise movement at the periphery of a rotary drum. A first testing device establishes a first pressure differential between the interior and exterior of successive wrappers, and a second testing device establishes a second pressure differential between the interior and exterior of those wrapper portions which surround tobacco as well as a different third pressure differential between those wrapper portions which surround the filter material. An evaluating circuit has two electropneumatic transducers which furnish first and second signals respectively denoting the pressure differential between the interior and exterior of successive wrappers and the pressure differential between the interior and exterior of successive wrapper portions which surround tobacco. A subtracting circuit furnishes third signals which denote the difference between the first and second signals. The first and third signals are compared with reference signals which respectively denote maximum permissible permeability of wrappers and minimum acceptable permeability of successive wrapper portions surrounding the filter material. Cigarettes wherein the permeability of wrappers is outside of the range between the maximum permissible and minimum acceptable permeability are segregated from acceptable cigarettes.
