摘要:
Plain cigarettes or other rod-shaped articles of the tobacco processing industry are finished and/or converted into filter cigarettes, and/or the envelopes of plain and/or filter cigarettes, cigarillos and/or filter mouthpieces are perforated and/or such rod-shaped articles are otherwise treated in or with an apparatus wherein at least one drum-shaped and/or at least one chain-shaped, endless belt-shaped and/or at least one other transfer conveyor receives articles from a maker, e.g., a plain or filter cigarette or cigarillo making machine. The transfer conveyor(s) delivers or deliver portions of or entire articles to one or more processing conveyors wherein or whereon the articles and/or their portions are treated (such as perforated, densified and/or otherwise manipulated) while in motion. The thus at least partly finished articles are returned onto the transfer conveyor(s).

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. Rolling movements of successive groups can be accelerated in several stages during and subsequent to entry into the channel, and this also applies for the deceleration of rolling movement ahead of, at and downstream of the outlet of the channel.

An electrical smoking system comprising a cigarette and an electric lighter, wherein the cigarette comprises a tubular tobacco mat partially filled with material tobacco so as to define a filled tobacco rod portion and an unfilled tobacco rod portion. The cigarette and the lighter are mutually arranged so that when the cigarette is received in the lighter, the electrical heater element of the lighter at least partially superposes at least a portion of the filled tobacco rod portion. The cigarette and the lighter are also mutually arranged so that when the cigarette is received in the lighter, the free end of the cigarette is occluded. The cigarette includes a zone of perforations at a location along the filled tobacco rod portion, with the cigarette being free of perforations along the unfilled tobacco rod portion. An apparatus for perforating a cigarette which can be smoked in an electrical smoking device includes a drum link-up assembly and a laser perforating apparatus. The apparatus can be used in a method of perforating a tobacco rod of the cigarette prior to assembly of the tobacco rod to a filter rod via tipping paper. In the method, a tobacco rod is supplied to the drum link-up assembly wherein the tobacco rod is moved from a combining apparatus to a tipping apparatus which attaches the tobacco rod to a filter rod by tipping paper. In making the cigarettes with a tobacco rod and a filter rod, a combining apparatus forms a continuous tobacco rod which is cut into 2-up tobacco rods.

Apparatus for increasing the permeabilities of central portions of tubular wrappers which form part of successive filter cigarettes of double unit length being turned out by a tipping machine. The central portions of the wrappers include adhesive-coated uniting bands which are convoluted around filter mouthpieces in a first portion of a rolling channel for successive filter cigarettes. A perforating unit which employs laser beams is set up to simultaneously perforate the central portions of the wrappers of several successive cigarettes in a second portion which immediately follows or partially overlaps the first portion of the channel. Each wrapper can be provided with two or more annular arrays of perforations.

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. The belt lifts successive cigarettes out of the respective flutes at the inlet and permits successive treated cigarettes to enter oncoming empty flutes at the outlet of the single rolling channel or each rolling channel.
摘要:
Fragments of plastic fibers, such as cellulose acetate fibers, forming part of mouthpieces of filter cigarettes or like rod-shaped smokers' products tend to become separated from the respective filter mouthpieces at the end faces which develop in response to the making of cuts across filter rod sections of double unit length between pairs of plain cigarettes to obtain filter cigarettes of unit length. The fragments of fibers which tend to become separated and to contaminate the area around the filter cigarette making machine are either bonded (e.g., by heat and/or by a solvent) to the respective mouthpieces, or are removed by suction and/or by resorting to electrostatic precipitation. It is also contemplated to cause smoke-permeable layers of filter material to overlie the end faces of the mouthpieces.
摘要:
A method and machine for producing ventilated cigarettes comprises forming a succession of double cigarettes, each comprising two cigarette portions and an intermediate double filter joined by an intermediate connecting band. The double cigarettes are translated to respective double cigarette supporting means on a rotary conveyor having an axis. The supporting means includes a rotatable gondola normally facing outward in relation to the conveyor and rotatable about the axis and rest means fixed in relation to the conveyor. Each double cigarette is arranged in engagement with the respective supporting means so that a first end portion of the double cigarette laterally engages the rotatable gondola. A second end portion of the double cigarette laterally engages the rest means. An intermediate portion of the double cigarette including the intermediate double filter is free. The conveyor is advanced to feed the double cigarettes through a perforating station. At the perforating station, each double cigarette is rotated about its axis by rotating the relevant gondola. At least two rings of ventilation holes are formed in the intermediate portion of each double cigarette as the gondola is rotated about its axis. The forming of the rings of ventilation holes comprises directing a pulsed laser beam along the conveyor axis, splitting the beam and directing the resulting beams divergently to concurrently impinge upon and perforate the intermediate portions of widely separated double cigarettes.

Successive filter cigarettes of unit length or multiple unit length are transported sidways on a first drum-shaped conveyor which cooperates in a filter tipping machine with a second drum-shaped conveyor to rotate successive cigarettes about their respective axes so that the rotating cigarettes come to a temporary halt in a predetermined portion of their path. Such cigarettes are acted upon the two or more laser beams or light beams which are equidistant from and angularly offset relative to each other in the circumferential direction of the cigarette which rotates about its axis so that a circumferentially complete portion of the rotating cigarette is acted upon by radiation while the cigarette completes a fraction of one revolution, namely an angle of 360 degrees divided by the number of beams. The first conveyor has peripheral advancing surfaces for individual cigarettes, and the length of each advancing surface in the circumferential direction of the first conveyor equals the circumferential length of a cigarette divided by the number of beams. The mutual spacing of cigarettes on the first conveyor is less than the mutual spacing of cigarettes on a conveyor which feeds successive untreated cigarettes to the first conveyor ahead of the rolling station and on a conveyor which receives successive treated cigarettes from the first conveyor downstream of the rolling station.
摘要:
Apparatus for making perforations in continuous or interrupted webs of cigarette paper or the like has one or more perforating units serving to direct radiant or electrical energy against selected portions of the web to make holes therein. That portion of each perforating unit which surrounds the locus of propagation of energy beyond the respective perforating unit is externally cooled and cleaned by one or more streams of compressed gas which ensure that such portion cannot accumulate solid combustion products which could interfere with the propagation of energy toward the web. The stream or streams are furnished by the orifices of nozzles which can be provided in the carrier or carriers for the perforating units or can be outwardly adjacent to the carrier or carriers.
摘要:
Apparatus for perforating a web of wrapping material or tubular wrappers of discrete filter cigarettes of unit length or double unit length in a filter tipping machine has a laser which is energizable at a frequency depending on the speed of the main prime mover of the machine to emit a beam which is reflected by a pivotable reflector to impinge alternately upon different portions of a single optical system or upon several discrete optical systems serving to focus the beam upon the web or upon discrete wrappers whereby the beam forms two or more rows or more complex patterns of perforations in the web or in the wrappers of successive cigarettes. The pivotable reflector can be omitted or is optional if a diffraction grating is placed in front of a single optical system so that the grating splits the beam into several discrete beams each of which is focused upon a different portion of the web or of the wrapper of a cigarette.
