Definitions

  • FIG. 2O ⁇ CIGARETTE AND APPARATUS TOR MAKING THE SAME Filed March so, 1955 e sheets-sheet 5 FIG. 2O
  • This invention relates to a method and apparatus for making an improved cigarette.
  • a cigarette a rm body so that it would feel well-formed and lled
  • This practice of over-lling to obtain a good feel was not desirable because it made the draw of the cigarette more difficult.
  • filter tips are placed on the end of such an over-filled cigarette, the draw of the cigarette becomes still more di'icult.
  • the present invention overcomes these various objections and difficulties by a unique arrangement which enables not only the end of the cigarette to be and appear fully compacted but also the cylindrical side walls of the cigarette so that they will have a full, rm feel. This accomplished without any overlling of the cigarette so that a cigarette with a very easy draw is obtained.
  • An object of this invention is to provide an improved means and method for densifying the end of a cigarette.
  • Another object of the invention is to provide a method and apparatus for varying the density of a cigarette along its length in accordance with the manufacturers requirements.
  • Figs. 1 3 are sectional side elevations of a double length cigarette disclosing the method of making dense end cigarettes and simultaneously lproviding a pocket for receiving a lter plug.
  • Figs. 4-8 are sectional side elevationsY of a cigarette illustrating the directional compacting forces exerted when the stepped plunger is progressively inserted .into the end of the cigarette.
  • Fig. 9 is a sectional side elevation of a dense end cigarette immediately after the plunger is retracted.
  • Fig. l0 is a sectional side elevation of the same cigarette shortly after retraction of the plunger.
  • Fig. ll is a sectional side elevation illustrating a suitable plunger activating mechanism for making my improved cigarette.
  • Fig. l2 is a sectional side elevation illustrating a knife passing through the compacted center portion of a double length cigarette to obtain two single cigarettes each having a compacted end on one end and an inserted lter plug Vat the other end.
  • Fig. 13 is a sectional side elevation of a single cigarette obtained [by this method, having a dense end on one end and an inserted filter plug on the other end.
  • Figs. 14-16 are sectional side elevations of a double length cigarette disclosing other devices for making my improved cigarette wherein the tobacco in the core area of the cigarette has less density than the tobacco adjoining the side walls of the cigarette.
  • Figs. 17-20 show how the improved cigarettes may have lter plugs or hollow tubes inserted into the ends of the cigarettes after the stepped plungers have been withdrawn, and also the manner in which the double length cigarettes are severed into two individual cigarettes.
  • Fig. 2l is a sectional side elevation illustrating a double length stepped plunger suitable for king-size cigarettes inserted in a double length cigarette.
  • Fig. 22 is a side elevation of a single length stepped plunger showing the exact construction and dimensions of one type of plunger which may be used for king-size cigarettes.
  • Figs. 1-10 I have shown how a stepped plunger with non-tapering steps can be employed for compressing the iiller tobacco in a cigarette both axially and radially.
  • stepped plungers wherein the base end of each step is cut down more than the far end of the step.
  • Such an arrangement is shown in Figs. 14-l6, 21 and 22, and has the advantage that the plungers can be readily withdrawn without pulling out tobacco shreds with the plunger.
  • the apparatus shown in Figs. 1-10 consists of a pair of clamps 10 and 1 for clamping a length of cigarette rod R having a Wrapper W.
  • a pair of elongated cylindrical stepped plungers 12 and 14 are moved in opposite directions as indicated by the arrow into opposite ends of the double length cigarette as shown in Fig. l.
  • the plungers 12 and 14 are slideably mounted in suitable -guiding brackets 16 and 18. Due to the steps 20, 22, 24, 26, 28 30, 32, and 34, there is effected two distinct actions.
  • the compression effected is primarily lateral, as shown in Fig. 4.
  • the second step 24 and 30 of the plunger enters into the end of the cigarette, the compression is still primarily outwardly as shown in Fig. 5, with a slight tendency to compress the tobacco longitudinally of the cigarette.
  • the third step 22 and 32 of the plungers 12 and 14 enters the cigarette, there is now a much more marked tendency to compress the tobacco longitudinally as shown in Fig. 5.
  • the fourth step 26 enters the cigarette, this tendency is still more marked as shown in Fig. 7.
  • the density of the tobacco in .the double length cigarette is below normal before the stepped plungers are inserted into the end of the cigarette.
  • the amount of tobacco in the finished cigarette will have to have its full normal density for only 54 mm. in length, due to the space occupied 'by the lilter plug. It will thus be seen that the 54 mm. normal tobacco density of the linished cigarette is uniformly distributed over the 70 mm. length of the cigarette prior to the insertion of the stepped plunger.
  • the iigures just mentioned would be double the amount set forth.
  • the end of the cigarette continues to remain densied as shown in Fig. 10 after the plunger is withdrawn, so that there is no tendency for the small shreds or shorts to fall out of the end of the cigarette.
  • Regular ller tobacco or filter plugs are then inserted into the hollow ends of the cigarette.
  • the double length cigarette is then severed across the densitied portion of the cigarette to make two cigarettes, each having a densilied portion of tiller tobacco at one end and tobacco iiller or a tilter plug at the other end.
  • the guide brackets 16 and 18 which carry the stepped plungers 12 and 14, respectively, are slideably supported in a suitable horizontal track 4t).
  • the free end of arm 50 is connected by means of a link 54 with the free end of a lug 56 projecting from the bottom side of the plunger supporting bracket 16.
  • the free end of arm 52 is connected by means of link 58 to the free end of a lug 60 projecting from the bottom side of the plunger supporting bracket 18.
  • Rotation of the pulley 46 and shaft 44 causes the plunger supporting brackets 16 and 18 to move towards and away from each other.
  • the elfect of the movement of said brackets towards each other results in the entry of the respective stepped plungers into the respective ends of the double length cigarette C and causes the compaction of the tobacco within said cigarette as described hereinbefore.
  • the clamp holding said double length cigarette may consist of two individual pockets 62 and 63 of a suitable turret 64 spaced in such a manner as to follow a suitable knife blade 66 to enter between the adjacent ends of said clamp pockets and etlect a cutting of the double length cigarette into two individual cigarettes as illustrated in Fig. 12.
  • the cutting is done through the densitied central portion of the double length cigarette.
  • a suitable filter plug or a hollow tube or a plug of tobacco or other desired material 70 is inserted manually or by suitable mechanism into the hollow ends of the cigarette.
  • Each individual cigarette F thus formed has a very desirable dense end D on one end and a iilter plug 70 or other suitable llng as indicated above on the other as disclosed in Fig. 13 of the drawings.
  • a cigarette clamping structure 72 and 74 for holding a double length cigarette C.
  • Sets of these clamps may be mounted along the periphery of a suitable rotating turret at spaced intervals, as shown, for example, in my co-pending application Serial No. 505,605, led May 3, 1955.
  • the cigarette liller in the cigarette Wrapper 76 is compressed axially and radially by the insertion of a cylindrical stepped plunger 78 into the end of a cigarette in the manner described above.
  • the stepped plunger made with steps which taper towards the fastened end of the plunger. Each step has the appearance of an inverted, elongated, truncated cone.
  • the stepped plunger 78 used to illustrate this embodiment consists of a cylindrical member having a plurality of steps 80, 82, 84, 86, each of which is Wider at its forward end than at its rear end.
  • a slidable sleeve 88 is mounted on each plunger and has a pin 90 extending through the sleeve 88 through the slot 92.
  • the slot 92 limits the distance the sleeve 88 can slide back and forth on the non-tapering shaft 94.
  • the leading end 89 of the sleeve 88 is tapered or cone-shaped to lit a slight distance into the mouth end of the cigarette holding clamps 72 and 74, respectively, when it is in cigarette holding position.
  • a compression spring 96 is mounted on each shaft 94, and continuously urges the sleeve 88 outwardly from the spring supporting shoulder 98.
  • the pin 90 will be pushed to a position of rest against the far end of slot 92 by spring 96.
  • the steps 80, 82, 84, and 86 will act on the tobacco in the manner heretofore described, and the nose or tapered end 89 of sleeve 88 upon engagement with the paper 76 and mouth end of clamp 72 will begin sliding back on the shaft 94 as the stepped plunger continues its advance inside of the cigarette.
  • the spring 96 is compressed in the manner shown in Fig. 15.
  • the stepped plunger 7S When the stepped plunger 7S is withdrawn from the cigarette, it does not pull any shreds of tobacco with it from the compressed cigarette filler because of the tapered arrangement of the individual steps 80, 82,184, and 86 of the plunger.
  • the importance of tapering the steps varies with the type and condition of the tobacco that is being handled. It has been found that there is less tendency for the compressed shreds of tobacco to adhere to the plunger when shaped in this manner, when being withdrawn, as shown in Fig. 16, especially if the filler has ⁇ a larger than usual amount of moisture and casing.
  • the tobacco at the forward end of the cigarette will be in a densiiied condition while the longitudinal axis of the ller will be less dense because of the insertion of the stepped plunger.
  • the tobacco around the periphery of the cigarette will also be in a compacted and idensiiied condition.
  • the stepped plunger is withdrawn there is a creeping back of tobacco from the side walls of the cigarette, but this creeping back does not restore the density of the tobacco along the center longitudinal axis of the cigarette to its precompacted density. It will thus be apparent that I have provided a cigarette which is of a design which gives the consumer and manufacturer many advantages they did not before have available.
  • Suitable means are then employed for inserting either a cigarette lter plug, a hollow tube, cigarette tobacco or other suitable material into the hollow cavity of the cigarette.
  • a cigarette lter plug a hollow tube, cigarette tobacco or other suitable material into the hollow cavity of the cigarette.
  • These filter plugs, hollow tubes, or lengths of conventional cigarette filler or other means are axially positioned in front of the center of the cigarette holding clamps by means of suitable locating devices 100 which may be similar to the structure shown in my co-pending application.
  • suitable ejecting plungers 102 are employed for pushing the cigarette filter, hollow tube, or other plug member into the cavity formed by the stepped plunger 78.
  • the center core or longitudinal axis of the cigarette is of lighter density than the end and the side walls of the cylindrical cigarette.
  • filter material or other suitable material does not have to be in plug form, but could be in a continuous rope of tobacco which is severed after the ⁇ required amount of such filter material or other material as has been injected into the cigarette directly from the cigarette rod or rope making machine.
  • Apparatus for manufacturing filter plug cigarettes comprising a clamp for holding a double length cigarette while maintaining it free from deformation, a plunger having fixed graduated cylindrical steps positioned at each end of said clamp, means for moving said plungers together into and out of engagement with opposite ends of said double length cigarette to compress the cigarette filler lengthwise and 'a knife for severing said double length cigarette into two cigarettes.
  • Apparatus for forming filter plug cigarettes comprising a ⁇ cigarette holding clampv having a cigarette clamping surface conforming to the configuration of a double length cigarette, plungers having fixed graduated steps mounted at opposite ends of said clamp for compressing the tobacco filler in said cigarette lengthwise to provide a space for a iilter plug, means for moving said stepped plungers simultaneously into and out of engagement with the opposite ends of said double length cigarette to compress the cigarette filler, means for inserting a filter plug into the end of the cigarette into which said stepped plunger was inserted, and a cutter for severing said double length cigarette across the middle to form two individual cigarettes.
  • Apparatus for manufacturing filter cigarettes comprising 4a clamp for holding a double length cigarette, plungers having cylindrical steps of fixed length to be inserted into opposite ends of the double length cigarette held by said clamp to compress the tobacco therein at the center of said double length and a cutter to sever said double length cigarette transversely across the center of said compressed portion of tobacco to form two iudividual cigarettes.
  • Apparatus for manufacturing cigarettes ⁇ comprising means to form double length cigarettes having a filler of desired density, a clamp having a configuration conforming to the diameter of a nished cigarette clamping each double length cigarette, oppositely spaced plungers having iXed cylindrical graduated steps usertable into opposite ends of said cigarettes so as to compress the tobacco ller therein lengthwise to the desired density and to make room for a iilter plug and a cutter to sever said double length cigarette at the middle to form two individual cigarettes.
