Abstract: A machine for manually making cigarettes having a frame, a pair of generally parallel rollers rotatably mounted to the frame with at least one of the rollers also being slidably mounted so that it may be moved laterally toward the other roller, and an endless belt trained over the rollers.

Abstract: A packaging for manual rolling of cigarettes comprising smoker's accessories like cigarette sheets, filters, sheets, matches, lighters, tobacco and an article usable as an advertising material is characterized in that the base line is foldably divided into two small sides with a narrow band therebetween. The intermediate band is terminated at both sides each time with two triangular parts, providing for creating a handy table for rolling cigarettes. The narrow band is foldably divided in a way that the external parts are embraced by triangular folded corners of smaller sides. While the device is in use, the packaging is opened and put onto a support in a way that small sides are lifted upwards. The triangular sides on both sides of the narrow band are then pushed upwards to create bulges. The two bulges each from its side stop the narrow side and prevent the content from falling from the support.

Abstract: A component of a cigarette comprises a silver-based catalyst for the conversion of carbon monoxide to carbon dioxide. The silver-based catalyst comprises particles (e.g., nanoscale or larger sized particles) of metallic silver and/or silver oxide supported in and/or on metal oxide support particles. The silver-based catalyst can be incorporated into a cigarette component such as tobacco cut filler, cigarette paper and cigarette filter material to reduce the concentration of carbon monoxide in the mainstream smoke of a cigarette during smoking. The catalyst can also be used in non-cigarette applications.

Abstract: A curling device for a filter tip attachment comprises at least one blade-like element offered to a continuous strip of paper material at a selected contact zone in such a way as to deform the material as it advances, so that single tipping papers separated from the strip by a cutting unit of the attachment are given a curved profile and as a result more easily wrapped around and affixed to the assembled filters and cigarette sticks when these are joined together; the curling device also comprises a delivery system by which the contact zone is flooded with a cushioning fluid designed to favor a smooth sliding contact between the curling element and the running strip, and at the same time equalize the tensions in the strip preceding and following the contact zone.

Abstract: A continuous tobacco rod generated by a machine for making tobacco products is separated into reclaimable lengths by a device that comprises a pair of tension rollers designed to exert a pulling force on the rod, also a pair of brake rollers operating upstream of the tension rollers and serving to offer a measure of resistance to the action of the tension rollers; as a result of the interaction between the tension rollers and the brake rollers, the portion of the continuous rod extending between them is forced to break by tearing apart.

Abstract: An additive material is applied to a substrate, such as a paper web used as a wrapping material for cigarette manufacture. A predetermined pattern of additive material is applied to the outer surface of the wrapping material of a formed cigarette, and most preferably of a formed filtered cigarette. In particular, an application system for applying additive material of a controlled type, in a controlled manner and in a controlled location on the wrapping material of a formed two-up filtered cigarette rod is located within a tipping machine. During controlled rotation of each such formed rod (e.g., due to cooperation of (i) a roll drum, and (ii) cooperating roll block and star drum), additive material is applied to the outer surface of a desired location of the wrapping material of each such rod.

Abstract: In a cigarette maker comprising a descent channel filled with shredded tobacco by a carding unit and with reclaimed tobacco by a conveyor, the shredded tobacco and the reclaimed tobacco are taken up and transferred by a toothed unit toward an ascent channel, from where both are attracted onto a belt by suction and formed into a continuous stream; the descent channel is split into two distinct portions serving respectively to admit the shredded tobacco and the reclaimed tobacco, whilst the toothed unit comprises a first and a second roller positioned to take up the shredded tobacco and reclaimed tobacco and operating in conjunction with respective impeller rollers.

Abstract: A forming device applied to a cigarette manufacturing machine causes a garniture tape 10 to travel through a wrapping section 8, and meanwhile wraps a shredded tobacco layer T in wrapping paper P to form continuously a cigarette rod R. The tape 10 is guided to travel by a forming guide 18 in the wrapping section 8, and is simultaneously bent to have a cross section of an arc that is downward convex. On the other hand, the travel of the tape 10 is guided by a pair of guide rollers 24 in upstream and downstream sides of the wrapping section 8, and the tape 10 is bent to have a cross section of an arc that is upward convex by guide surfaces of the rollers 24. Thus, difference of travel length, that is generated between both side edges and the central part of the tape 10 in the wrapping section 8, is offset by the guide rollers 24.

Abstract: Adhesive-coated bands of paper, tipping paper or plastic foil are convoluted around discrete one-piece or composite rod-shaped articles, such as coaxial plain cigarettes and filter mouthpieces, during travel through a rolling zone bounded by a pair of surfaces at least one of which moves relative to the other. The inlet of the rolling zone receives articles, each of which carries a non-convoluted band, from a conveyor which forms part of a pressing device operative immediately ahead of the inlet of the rolling zone and serving to press successively delivered bands against the respective articles and to effect an at least slight flattening of the articles immediately prior to entry into the rolling zone. The width of the path for the articles increases at the outlet of the rolling zone or immediately downstream of such outlet.

Abstract: Device for wrapping groups of filter segments with a wrapping material. The device includes a rolling channel defined between adjacent stretches of at least one first roller conveyor and at least one second roller conveyor. The rolling channel is structured and arranged to wrap the groups of filter segments with the wrapping material by rolling each of the groups of filter segments. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: Filter cigarettes of unit or multiple unit length are produced in a tipping machine wherein successive groups of coaxial plain cigarettes and filter rod sections are caused to roll within a channel bounded by surfaces at least one of which moves relative to the other(s). This results in the conversion of uniting bands, which are carried by successive groups into the inlet of the channel, into tubular sleeves connecting the tubular wrapper(s) of the filter rod section(s) to the plain cigarette(s) of the respective group. The wrappers, and normally also the uniting bands, are perforated in the channel subsequent to, or in part simultaneously with, the conversion of uniting bands into the respective sleeves. Each filter cigarette can be provided with one or more arrays, such as annuli, of perforations, e.g., by mutually inclined laser beams.

Abstract: Cigarettes are manufactured on a machine that includes a filter tip attachment comprising a train of rollers with peripheral suction grooves, each proportioned to hold a single cigarette. The grooves are set parallel to the axis of rotation of the relative rollers and combine to establish a feed path along which the cigarettes are attracted and released, passing from one roller to the next and advancing through a succession of processing stations. To optimize the attraction and release steps, the cigarettes themselves are exploited in such a way as to create a chamber in each groove, compassed between the cylindrical surface of the cigarette and the bottom surface of the groove it occupies, and connected to the pneumatic circuits generating the suction.

Abstract: Tubular envelopes of successive rod-shaped products, such as cigarettes and/or filter rod sections, are caused to turn about their longitudinal axes and to simultaneously move sideways during advancement through a perforating station. At least one laser or another source of high-energy radiation directs at least one beam of radiation against a radiation-reflecting body which is caused to turn about its axis and has one or more curved, such as helical, surfaces serving to cause migration of and to simultaneously reflect the beam or beams upon one or more selected portions of the envelope of the rod-shaped product then moving through the perforating station. The thus refected beam(s) perforates or perforate the envelope being advanced through the station.

Abstract: Successive cigarettes of a series of cigarettes, such as filter cigarettes, are transported sideways in the axially parallel peripheral flutes of a rotary drum-shaped conveyor to the inlet(s) of a straight or V-shaped rolling channel or of two successive straight channels defined by the rolling surface(s) of one or two stationary block-shaped rolling members and the external surface of an endless belt trained over several rollers and being at least partially confined in a recess or groove of the conveyor in such a way that the surface(s) of the rolling member(s) cooperate with the surface of the belt to roll successive cigarettes in the channel or channels about their longitudinal axes while one or more beams issuing from one or more lasers or other radiation source(s) impinge upon the wrappers of the cigarettes rolling in the channel or channels.

Abstract: An apparatus, such as a filter tipping machine, wherein groups of coaxial rod-shaped articles are connected to each other end-to-end by adhesive-coated uniting strips or bands, employs two endless conveyor belts having parallel stretches defining an elongated rolling channel and moving in the same direction but at different speeds. A first rotary drum-shaped conveyor is employed to deliver successive groups, each of which can carry a uniting band, sideways into the inlet of the channel wherein the groups are caused to roll and the uniting bands are convoluted around them. A second rotary drum-shaped conveyor receives successive groups of interconnected rod-shaped articles from the outlet of the rolling channel and delivers them to a processing station, such as a severing or packing station, or to a magazine. One of the endless conveyor belts is trained over the drum-shaped conveyors.

Abstract: The invention relates to a suction strand conveyor of a cigarette strand machine, which is guided around a contact wheel in an inlet area of a shaping arrangement. A plurality of suction air channels connect an inner bearing space of the contact wheel and an outer surface of the contact wheel with a suction chamber of the suction strand conveyor belt and provide a permanent removal of tobacco dust.

Abstract: Groups of coaxial plain cigarettes and filter mouthpieces, particularly cigarettes and mouthpieces having elliptical cross-sectional outlines, carry adhesive-coated uniting bands at the time of entry into a channel between the peripheral rolling surface of a rotary drum and the complementary rolling surface of a stationary rolling member. The uniting bands are convoluted around portions of or the entire mouthpieces and around the neighboring portions of the respective cigarette or cigarettes. The inlet of the channel is defined or preceded by a transversely extending stationary group-contacting device having a raised first portion which cooperates with the drum to set the mouthpieces and the cigarettes of successive oncoming groups into simultaneous rolling motion, and such first portion is followed by a second portion having a concave guide surface which ensures predictable entry of successive groups into the rolling channel downstream of the first portion.
