Definitions

  • This invention relates to smoke filter plugs or wads for cigarettes, cigarette holders, cigars, to-
  • the smoke filter wad of a single spiral located within a cigarette paper the smoke filter wad of a single spiral located within a cigarette paper
  • the center of the spiral a will contain a free channel b which will be the wider, the greater the thickness of the ribbon from which the spiral is wound.
  • This central channel will oifer the least resistance to the smoke so that agreat part of the smoke will flow through this channel instead of through the narrower air gaps between the windings. This will reduce the absorbing effect of the plug.
  • the multiple crepe paper ribbon forming the wad is doubled at the central part of the wad, so that at least the central part of the wad consists of a double-wound spiral.
  • a further object of the invention is to prevent the paper ribbon from slipping out of the space enclosed by the rollers through the gap between the rollers opposite to the gap, through which the paper ribbon is fed between the set of rollers.
  • Another object is to secure the rolling of a regular spiral.
  • a further object of my invention isto provide a machine securing exact supplying, feeding, cutting and forwarding of the strip material towards the apparatus for rolling the material, in a length necessary to form the smoke filter wad or plug.
  • the supply roll of the machine is provided with an automatic driving device which consists of a frictional driving roller positively driven from the shaft driving the feeding device of the plug rolling'device and arranged on a pivotal ,arm, provided with means to press said driving roller in a yielding manner towards the circumferential surface of the supply roll.
  • an automatic driving device which consists of a frictional driving roller positively driven from the shaft driving the feeding device of the plug rolling'device and arranged on a pivotal ,arm, provided with means to press said driving roller in a yielding manner towards the circumferential surface of the supply roll.
  • Figure 1 is a cross-section of one form of wad according to my invention.
  • Figure 2 is a cross-section of a wad according to this invention on an enlarged scale.
  • Figure 3 is a diagrammatical side elevation of the machine for the manufacture of the wads.
  • Figure 4 is a lateral view seen from the right side of Figure 3.
  • Figure 5 is a side elevation and Figure 6 a vertical cross-sectional view of a rolling device for rolling a spiral according to Fig. 2.
  • Figure 7 shows a cross sectional view of another form of the rolling device and the guiding means co-operating therewith at the beginning of the rolling of the spiral plug.
  • Figure 8 is a view similar to Figure 7, at the completion of the spiral plug.
  • Figure 9 is a front view seen from the left side of Figure '7.
  • Fig. 10 is a schematic showing of the rolls and the drive means therefor.
  • c is the cigarette paper tube and a is the multiple crepe paper ribbon doubled upon itself at its center part d so that a double spiral is formed, which fills out uniformly the whole cross sectional area of the cigarette paper tube.
  • crepe paper instead of crepe paper a regularly corrugated paper can be used.
  • the machine for the manufacture of the said wads or plugs comprises first a supply roll 1 ( Figure 3) journalled on pin 2 in support 3.
  • the corrugated paper ribbon as taken from supply roll 1 is led over roller 4 towards the feeding device 5, 5 of the rolling device 1' for rolling the smoke filter plugs, as hereinafter described.
  • '7 is a usual knife for cutting the length of ribbon to be rolled, driven in known manner from the driving shaft of the machine.
  • roller 8 is a frictional rollerv journalled in arm 9 which is pivoted at 10 in support 3, and 11 is a spring which presses roller 8 against the circumferential surface of supply roll 1.
  • Roller 8 is driven by means of a string or chain gear 12, 13, 14 ( Figure 4) from a wheel 15 journalled on the pivot pin 10 of lever 9 while wheel 15 is driven for example by means of a string or chain 16 from the same shaft 17 which drives the shaft 18 of the feeding device 5, 5 of the device 1' rolling the smoke filter plugs.
  • roller 8 rolls the supply roll positively, and automatically assumes the angle to the periphery thereof required to supply exactly the same length of ribbon a which is cut at 7 from the ribbon a and fed into the rolling devicer, so that the ribbon a will not suffer any stretching whatever.
  • the rolling device 1' consists of a plurality of rollers r1, r2, ra'and 1'4 adapted to be turned by a suitable gearing, shown in Fig. 10, in the same direction shown by the arrows.
  • a suitable gearing shown in Fig. 10
  • the upper pair 1'1, r: of the rollers may be journalled in a movable bracket, so that it can be lifted and adjusted with respect to the lower pair of rollers.
  • an abutment 19 is provided opposite to the feeding gap between rollers 1'1 and n'within the free space enclosed by the rollers.
  • the foremost edge 20 of the paper strip a will strike against abutment 19 so that when strip a is pushed forward by roller 11 and a guide co-operating therewith, shown in the drawings, with dotted lines, the end of strip a will be doubled to form the S-shaped central part a: ( Figure 2) of the wad.
  • r1, r2, rs and n are again the rollers adapted to be turned in the same direction.
  • 21 is a guiding plate, from which the paper ribbon a to be rolled is introduced through the gap between the rollers 11 and n.
  • the rollers are provided with at least one, preferably with a plurality of circular grooves or slots 22 (according to Figure 9- with two such slots).
  • guide tongues 23 are projecting through grooves 22 which bar the passage of the paper ribbon a through the gap 24 between the rollers r2, m which is opposite to the feeding gap between rollers 1'1 and m.
  • the paper strip a is introduced between the rollers r1, 1-4 and roller r1 drives the paper ribbonso that the central part of the spiral will be doubled. If that is not desired, the edge 25 is made more or less oblique.
  • tongues 26 may be arranged to project through grooves 22 into the space enclosed by the rollers.
  • Tongues 26 are provided at their upper end with a curved outer guiding edge 27 to bend the paper strip a upwards and to lead the same in tangential direction towards guiding edge 25.
  • the forward edge of guiding tongues 26 are provided with a substantially semi-circular recess 28 helping to roll the innermost end of the paper strip a, as shown in Figure 7.
  • Guiding tongues 26 are pivoted at 29 and springs 30 tend to draw said guiding tongues into the position shown in Figure 7.
  • a piston 32 ( Figure 9) pushes the plug, in known manner, in its axial direction into a channel or sleeve 33 wherefrom it is introduced in any well known manner into the cigarette paper tube.
  • a machine for the manufacture of wound articles comprising means for feeding the stock to be wound, two sets of upper and lower rolls mounted closely adjacent to each other, means for guiding the stock between the first set of rolls, means for turning the said rolls, means extending between the rolls of the second set and having a surface adapted to receive and deflect stock after it passes through the first set of rolls, and resilient means also extending between the rolls and adapted to yieldingly cooperate with the said deflecting means for guiding the stock into its properly wound position.
  • a machine for the manufacture of wound articles comprising means for supplying stock to be wound, two sets of upper and lower rolls mounted closely adjacent each other, means for guiding the stock between the rolls of the first set, means for rotating the rolls, and abutment means extending between the upper and lower rolls of the second set, and adapted to receive and deflect the stock after it is fed between the rolls of the first set, and spring-biased means also extending between the said rolls and having a recess therein adapted to yieldingly abut and guide the stock as it is deflected by the said abutment means and rolls into its finally turned position.
