Abstract: Apparatus for removing surplus at one side of an unequalized tobacco stream includes a transporting unit with a pneumatic conveyor having an endless foraminous belt which overlies the stream and defines with two sidewalls a channel for advancement of the stream along an elongated path so that the surplus extends downwardly beyond a preselected distance from the underside of the belt. The mechanism for trimming the surplus off the moving stream comprises two disc-shaped gripping members which define a nip for the entry of successive increments of the stream directly above the surplus, and a rotary knife having a circular cutting edge which separates the surplus from the major portion of the stream immediately below the nip. The knife can form part of or can be disposed immediately above a coaxial rotary deflector which directs the severed suplus in a desired direction. A driven rotary paddle wheel can be installed upstream of the nip to remove some of the surplus, and a rotary device which compacts longitudinally spaced apart portions of the stream can be installed between the paddle wheel and the nip.

Abstract: The diameters of successive rod-shaped articles of the tobacco processing industry are ascertained while the articles advance in the flutes of a conveyor, first along a rolling unit which turns successive articles at random through different angles and thereupon past a photoelectronic detector wherein a radiation source emits a narrow beam of radiation which impinges upon successive articles for intervals of time which are dependent upon the diameters of the articles. The transducer of the detector generates signals which are indicative of the monitored diameters, and such signals are transmitted to an evaluating circuit which controls an ejector for unsatisfactory articles and/or displays the monitored diameters on a screen. The articles are partially lifted off the conveyor by cushions of compressed air during transport past the rolling unit.

Abstract: 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.

Abstract: A stream of tobacco particles which is built at the underside of the lower reach of an endless foraminous belt conveyor is trimmed to remove the surplus, and the resulting filler is draped into a web of cigarette paper while advancing through a wrapping mechanism. In order to reduce friction in the wrapping mechanism, the stream is shaped, at least in part, to assume a cross-sectional outline conforming to that of the wrapped filler. Such cross-sectional outline can be imparted by the conveyor and/or by the trimming device. The web of cigarette paper is also shaped on its way toward the wrapping mechanism to assume the shape of a trough.

Abstract: The exterior of successive filter cigarettes, filter rod sections or other rod-shaped articles of the tobacco processing industry is monitored for the presence of various defects including absence or improper orientation of filter mouthpieces, improperly applied or outwardly projecting uniting bands, absence of roundness and/or others by directing a beam of radiation along successive articles while they move sideways in the flutes of a drum-shaped conveyor. The beams of radiation are influenced by defects and are thereupon monitored for the purposes of generating signals which are indicative of defects, if any. The beam of radiation extends all the way along the full length of each article and can also extend partially or around the entire circumference of each article.

Abstract: 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.

Abstract: A composite tobacco stream is built at the underside of the lower reach of an air-permeable belt conveyor below a suction chamber by showering tobacco particles of a first type into the corner between one marginal portion of the lower reach and a first sidewall bounding a tobacco channel at the underside of the lower reach, by thereupon showering tobacco particles of the first type into the corner between the other marginal portion of the lower reach and a second sidewall so that the particles form a first tobacco layer having a concave underside, by thereupon depositing a relatively narrow core consisting of tobacco particles of a different second type on the underside of the first layer midway between and spaced apart from the two marginal portions of the lower reach, and by thereupon showering tobacco particles of the first type over the core as well as over the marginal portions of the first layer. The core can be formed by showering tobacco particles of the second type directly against the central zone of the concave underside of the first layer, or by building the core on a separate conveyor and transferring the thus formed core onto the first layer.

Abstract: The height of a continuous tobacco stream between a first side which is supported by a conveyor and an uneven second side is monitored by an opto-electrical level detector which directs a row of parallel light rays transversely across the stream and has a battery of photosensitive elements at different distances from the first side of the stream so that each element produces a signal in response to impingement of a different light ray upon its photosensitive surface. The number of elements which generate signals is indicative of the height of the stream portion advancing past the level detector. Such signals can be utilized to adjust a trimming device which removes the surplus at the second side of the stream before the thus equalized stream enters a wrapping mechanism to be converted into a cigarette rod which is thereupon severed to yield discrete cigarettes.

Abstract: A web which is converted into wrappers of plain or filter cigarettes, or the wrapper or each cigarette is perforated by needles, teeth, punching tools, sparks or laser beams prior to arrival of corresponding cigarettes at a pneumatic testing station. The testing device at such station transmits signals which denote the permeability of successive wrappers, and the signals are compared with a reference signal denoting the desired permeability of wrappers. If the monitored permeability deviates from the desired permeability, the device which makes holes in the web or in the wrappers is automatically adjusted to change the combined area of holes.
