Definitions

  • This invention concerns improvements in or relating to the manufacture of rods in which a web of paper is folded, so that portions of the web overlap, into rod shape (e.g., cylindrical shape), the said overlapping portions being joined together to seal the rod, and in particular to a continuous rod cigarette-making machine in which a tobacco filler is wrapped in a cigarette paper web.
  • rod shape e.g., cylindrical shape
  • tobacco filler when used herein, is intended to denote not only a filler consisting wholly of tobacco, but also any filler suitable for incorporation in a wrapper to form a cigarette rod, and includes, for example, a filler consisting of portions of tobacco between which are spaced mouthpiece portions, as is sometimes used in the manufacture of mouthpiece cigarettes.
  • the word filler i to be understood as including a filler of any material, e.g., filtering material, which is enclosed in a paper or the like to form a continuous rod.
  • a tobacco filler is deposited on a moving web of cigarette paper, which is wrapped about the tobacco filler to form a continuous cigarette rod.
  • Adhesive is usually applied to one edge portion of the paper web, the latter then being folded about the filler o that the said edge portion overlaps the other edge portion of the paper web, and adheres thereto so as to enclose the tobacco filler.
  • the continuous cigarette rod so formed then normally passes beneath a heating device to seal the overlapped, adhering edge portions of the paper web.
  • a similar technique is used in making a continuous rod of mouthpiece material for the production of cigarette mouthpieces such as filter plugs.
  • apparatus embodying the invention contains an ultrasonic vibratory welding device arranged to act on the aforesaid overlapping edge portions to form the said seam.
  • welding In relation to the joining of parts made of materials such as metals or synthetic plastic materials, the term welding is employed as meaning uniting by fusing together contacting portions of the parts to be joined. Usually fusion is achieved by the application of heat, although the heat may not be applied as such, but may be generated within the material.
  • heat may not be applied as such, but may be generated within the material.
  • radio-frequency electromagnetic energy may be directed on to metal articles so as to induce so-called eddy currents within the metal and hence heat the latter.
  • Such intermingling of the fibres may be considered as comparable with welding of fusible materials, in that two articles are joining by causing intermingling of the material adjacent to contacting surfaces of the two articles, hence by analogy a joint so produced between pieces of paper is herein termed a weld.
  • Such a mechanical impedance transformer serves to convert relatively low-pressure vibrations exerted over a large area to relatively high-pressure vibrations exerted over a small area (using the term pressure in its strict sense of force-per-unit area) and comprises an exponentially tapered rod.
  • the tongue which is employed in such machines to compress the tobacco filler during the final stages of folding the paper wrapper around said filler serves as the support member or anvil which coacts with the vibrating member in the ultrasonic vibratory welding operation; it is of course necessary to employ the downstream (considered in the direction of movement of the filler and paper wrapper) end of the tongue for this purpose, as at the upstream end folding of the paper has not been completed so that the edge portions of the paper are not in proper overlapped relation, ready for welding, as they pass said upstream end.
  • Such a machine incorporates folding means in the form of one or more (usually at least two) guide members shaped to guide the edge portions of the cigarette paper web into overlapping relationship.
  • Any of the known forms of guide members (often termed folding blades) may be so employed; at least one of such members extends at least as far as the downstream end of the tongue mention above, being apertured to permit access of the vibrating member to the paper so that said tongue may be employed as a support member as above mentioned, and to ensure that the overlapped edge portions of the paper are held by at least one of the guide members until welding has been effected.
  • FIGURE 1 is a plan view, partly in section of part of the apparatus on a continuous rod cigarette-making machine.
  • FIGURE 2 is a partial sectional view on the line IIII of FIGURE 1, the tongue support being omitted for clarity.
  • FIGURE 3 is a partial sectional view on the line IIIIII of FIGURE 1.
  • a continuous cigarette paper web 1 having side edges 2 and 3 is moved lengthwise in the direction of the arrow on a moving conveyor tape 4 through a U-shaped channel having converging side walls 5 and 6 which cause the edges 2 and 3 to assume the positions shown in FIGURE 1.
  • a tobacco filler (not shown) is carried on the web 1, and the side edges 2 and 3 gradually move upwardly to partially enclose the filler as the paper 1 moves through the channel.
  • the tongue 7 slopes and is tapered towards its downstream end (the left hand end in FIGURE 1), but a small part 9 adjacent its extreme downstream end as viewed in plan is devoid of taper, i.e., has parallel sides.
  • the guide part 10 is located upstream of the part 11, and as the web 1 moves .past the tongue 7 with the edges 2 and 3 positioned one on each side of and slightly above the tongue, the edge 2 engages the guide edge 12 and is guided inwardly as viewed in plan, and downwardly towards the tongue 7 (FIGURE 2). Further downstream the edge 3 also engages the guide edge .12 and is guided inwardly and downwardly to move over the edge 2.
  • the slightly overlapping edges 2 and 3 are further guided into overlapping relationship by the guide edge 13, and are held in overlapping relationship by a stationary guide member 14, which is shaped with a longitudinal groove of semicircular cross section (FIGURE 3) to aid in guiding the paper edges 2 and 3 into overlapping relationship.
  • a stationary guide member 14 which is shaped with a longitudinal groove of semicircular cross section (FIGURE 3) to aid in guiding the paper edges 2 and 3 into overlapping relationship.
  • Part of the member 14 is positioned above the tongue 7, to hold the paper edge portions in overlapping relationship against the part 9 of the tongue 7.
  • the paper edges 2 and 3, being held in overlapping relationship by the member 14, tend to move together and downwardly upstream of the member 14 on account of the stiffness of the paper.
  • the edge 3 is therefore already folded over slightly before it engages the guide edge 12, the latter acting to further guide the edge 3 downwardly and over the edge 2.
  • the tape 4 remains in contact with the web to support the latter, said tape eventually enclosing the web and filler almost completely (FIGURE 3), only the overlapped edge portions 2, 3 and closely adjacent areas of the web being left uncovered.
  • the guide parts 10, 11 and the member 14 constitute, in combination, folding means to fold the portions of the paper web .1 adjacent the edges 2 and 3 into overlapping relationship about the part 9 of the tongue 7, so that the latter lies between the tobacco filler and the overlapping paper edge portions.
  • an aperture in the form of a hole 16 is provided in the member 14 directly above the part 9 of the tongue 7, so that the overlapping paper edge portions are exposed as they move beneath the hole 16.
  • An ultrasonic vibratory welding device comprising a transducer 17 connected to a coupler 18 serving as a mechanical impedance transformer and having a welding tip 19, is positioned above the hole 16 so that the tip 19 can act through the latter.
  • the welding tip 19 acts on the overlapping paper edge portions as they move heneath the hole 16, and welds them together, while they are supported by the part 9 of the tongue 7, to form a seam 20 running lengthwise of the wrapped continuous cigarette rod 21.
  • the rod 21 then passes to cut-off mechanism (not shown) of the cigarette-making machine to be cut into individual cigarette lengths.
  • Each cigarette so formed thus has a seam comprising overlapped ultrasonically welded edge portions of the cigarette-paper wrapper, the seam running lengthwise of the cigarette.
  • the tip 19 is substantially rectangular in section (FIG- URE 1), having dimensions of 1 mm. by 5 mm, and its surface is concaved slightly to correspond to the upper surface of the part 9 of the tongue 7 (see FIGURE 3). With a tip of this shape and size a single line seam, approximately 1 mm. in width, is formed, but it will be understood that other forms of tip may be employed to give seams of different characteristics.
  • the tip 19 may be made of any suitable material; a metal tip is preferred but a nonmetallic tip, such as diamond or sapphire with a roughened surface, may be employed to provide a rougher appearance to the welded seam which more closely resembles the appearance of the remainder of the cigarette-paper. If desired, the paper web may be dampened before welding. An additive, such as china clay, to the paper web may be used to assist in the welding operation.
  • the transducer diagrammatically shown at 17 in FIG- URE 3 is preferably of a known magnetostrictive type, having a polarising coil and an excitation coil, and the frequency of vibration used is 22 kc./sec.
  • the frequency of vibration used is 22 kc./sec.
  • other types of transducers for example piezoelectric transducers employing barium titanate etc. can also be used, and that other frequencies of vibration (e.g., within the range 20 to kc./sec.) may be employed.
  • apparatus for wrapping the tobacco filler in the paper web comprising folding means to fold the paper web about the filler so that one edge portion overlaps the other edge portion of the paper web, a compression tongue positioned to lie between the filler and said overlapping edge portions to compress the filler, a member provided with a vibrating welding tip, said folding means including a stationary guide member past which the paper web moves, said guide member being shaped to guide the edge portions of the paper web into said overlapping relationship about a downstream end part of the tongue, considered in the direction of movement of the tobacco filler, so that said part of the tongue lies between the filler and the overlapping paper edge portions and being positioned to hold the paper edge portions in said overlapping relationship against said part of the tongue While the paper is welded, said guide member being so shaped as to define an aperture through which said welding tip extends, and means to cause ultrasonic vibratory motion of said welding tip so as to produce
  • apparatus for wrapping the tobacco filler in the web comprising an arcuate, relatively thin, elongated tongue, means for supporting said elongated tongue parallel to the direction of movement of and adjacent to said filler such that the concave side of said tongue compresses said filler, the upstream portion of said tongue, considered in the direction of movement of the tobacco filler, being secured to said support means, a welding tip spaced from the convex side of the downstream portion of said tongue, said welding tip being substantially rectangular in section with its surface adjacent said tongue being concave corresponding to the adjacent arcuate surface of said tongue, means for folding said web about said filler and tongue such that the longitudinal edge portions of said web overlap at a position located between said tongue and said welding tip, and means for producing ultrasonic vibratory motions of said welding tip relative to said tongue causing an ultrasonic cyclic variation of the spacing between said tongue and said welding tip whereby said overlapping edge portions of
