Definitions

  • This invention relates to an improved method and apparatus of forming crimped continuous filament tow into tobacco smoke filters. More particularly, this invention relates to a method and apparatus for forming a lower denier per filament, more highly crimped tow than has heretofore been used into filter rods for cigarette tips.
  • This invention has for one object to provide a process of condensing a bundle of continuous filaments to a smaller diameter under little or no tension whereby a substantial percentage of each filament is positioned more nearly crosswise to the longitudinal axis of the filament bundle. Still another object is to provide a process of condensing a bundle of filaments to a smaller diameter whereby there is obtained a firmer and more fully packed filter element than obtainable by prior methods. Still a further object is to provide a process of condensing a bundle of filaments by means of an aspirating action of air or the like gas in a manner whereby the filaments are pushed rather than pulled into the compacting mechanism.
  • Still another object is to provide a process of making filter rods particularly adapted for the attachment to cigarettes, which process is relatively simple and more eflicient than prior art processes.
  • Another object is to provide an apparatus for making filter elements from continuous filaments, which apparatus contains an air jet in special combination with forming means.
  • Still another object is to provide a special cone-shaped jet particularly adapted for handling a bundle of continuous crimped filaments whereby the filaments may be motivated but still maintained in Other objects a relatively relaxed or untensioned state. will appear hereinafter.
  • the present invention where the filaments are motivated by air or the like gas in a manner which pushes the filaments into the compacting and forming means, even though finer more highly crimped filaments are used such filaments are not broken and an improved filter is obtained.
  • FIG. 1 is a semidiagrammatic side elevation view of apparatus for filter element manufacture comprising a machine having in combination therewith my novel aspirating jet.
  • FIG. 2 is also a semidiagrammatic side elevation View somewhat on an enlarged scale for clarity showing the aspirating jet in section and particularly showing the posi tioning thereof with respect to associated parts.
  • FIG. 1 will now be described in detail.
  • the figure will be considered from right to left. Namely, it will be assumed that a suitable bundle of crimped continuous filaments has been obtained and is being fed through the apparatus of FIG. 1 for forming a filter element.
  • the description will be of a path through the apparatus for forming the spread-out continuous filaments into a compacted filter element.
  • 1 designates the crimped continuous filament tow in a spread-out condition to be made into a filter element.
  • This band of filaments will comprise several thousand individual continuous crimped filaments which have previously been treated in certain desired manners. That is these filaments may be fiulfed, opened up by rolls, sprayed with plasticizer and the like. Further details concerning such treatment may be had from a review of the aforementioned Patent 2,794,480.
  • These filaments 1 pass over and around rolls 2 and 3 for motivating the filaments from the previous treatments such as finding, plasticizing, etc. to the treatment by the present invention.
  • These several thousand filaments then arrive at a position designated 4 where the filaments are about to be compacted and formed into a rod-like shape as a filter element.
  • This device 6 of the present invention is also positioned in close proximity so as to feed under and into the tongue 8 of the forming member designated overall as 9.
  • This forming member in the present instance for making cigarette filters is generally cylindrical in shape.
  • the forming member is generally of a configuration similar to the configuration of the filter which it is desired to produce. Therefore, since in the present instance it is desired to produce a cylindrical filter element generally conforming to the cylindrical shape of a cigarette, the
  • forming member is, on the upper surfaces thereof, cylindrical and tapered toward the exit end. However, the bottom portion of forming member 9 may be opened to some extent or otherwise constructed to accommodate an endless belt 11. This belt is driven by drum 12.
  • the belt passes over and under various rollers 13, 14, 15 and 20 -Whereby the belt rotates under forming member 9 as a conveyor for conveying the formed filter rods through the process.
  • the aforementioned driving drum and rollers are suitably positioned as shown in the drawing so that the belt passes under forming member 9 in a reasonably parallel manner.
  • a substantially endless web of wrapping material 16 such as paper.
  • This wrapping material is fed from supply roll 17 under and over suitable guide rolls 18 and 19. As shown in the drawing the wrapping material is brought into continuous contact with the formed filter element in a manner that the filter element may be enclosed in the wrapping material.
  • FIG. 2 Attention is now turned to Fig. 2 wherein the jet-6, the tongue 8 and the forming member 9 are shown on a larger scale. It will be further noted that the wrapping material 16, the endless belt 11, as Well as rollers 15 and 19 are also shown in this FIG. 2 on a larger scale.
  • let 6 preferably is of cone-shaped construction. That is, the jet overall can be considered somewhat as a truncated cone shape thereby having a considerably greater cross-section on the entrance end 34 than on the exit end 31.
  • the jet is made up of the inner member 32 and the outer. member 33. These parts are suitably threaded at 34- or otherwise fabricated so that they may be assembled together and provide the chamber 35 which encircles the entire inner member. Anopening into this chamber is provided at 36 which corresponds to the point where pipe 7 (of FIG. 1) enters.
  • the inner walls of this chamber as at 37 areshaped so as to provide an outlet orifice 38 around the periphery of the inner member. In other words, this outlet orifice permits the air or the like motivatinggas to escape out through the exit end 31 of the jet.
  • the jet 6 is preferably positioned at a certain angle to tongue 8 of the forming memher. 9. Also the jet is suitably shaped on the outside thereof, such as at 39 so as to permit the ready movement of the web of wrapping material thereunder as well as the movement of the endlessbelt 11.
  • the longitudinal axis of the jet is preferably positioned about 30 degrees above or below the longitudinal axis of the forming member 9.
  • the upper wall of the interior of the jet is about 45 degreesabove the horizontal axis of the forming member and the lower wall about 15 degrees above such horizontal axis.
  • While the air or other gas can be directly introduced into the. jet through conduit 7, if desired suitable control valves can be incorporated with the jet to provide the desired control over the volume and/ or pressure of the fluid going into the jet. That is, by using variable control in the gas line it i possible to produce filter rods W1th some variation in weights. Expressed in another Way, filter rods with more uniform weights and/ or pressure drops can be produced from filaments that may vary somewhat in weight.
  • the control may consist of a means of varying the air pressure applied to the jet or the orifice opening in the jet. In general, for making filter rods for cigarettes I prefer that the orifice 33 be of a diameter of about /s inch.
  • a band of several thousand continuous crimped filaments 7. pass over and under rolls 2 and 3 until they ar-. rive at position 4 where they are fed into the jet of the present invention. It is relatively easy to feed the filaments to the jet since the gas supplied to the jet causes it to be substantially self-threading.
  • the band of crimped filaments are positioned under tongue 3 into the forming means 9 where the filaments are compacted and formed into a cylindrical shaped filter element.
  • the wrapping material 16 is being continuously supplied and the endless belt 11 conveys the wrapped filter rod out of forming member 9 to the subsequent steps accomplished by parts 21, 22, and 23 of sealing the wrapping material around the rod and cutting the rod into suitable lengths.
  • one of the filter elements of each pair was compacted and formed by the prior art procedure of drawing or pulling the filaments through the forming memher.
  • the other filter of the pair was produced in accordance with the present invention and passed through jet 6 whereby the filaments were pushed by the air in a relaxed state into the forming member 9. This was accomplished by supplying approximatelyS p.s.i.g. of air through pipe 7 intothe jet.
  • a filter rod in accordance with the prior art and without using the jet of the present invention comprised of S D./ F., 60,000- total denier gave an average pressure drop of 5.9 inches of water and a weight of 0.813 gram per rod.
  • a rod made by the present invention gave a pressure drop of 7.94-
  • rods designated BNC were produced by the process of the present invention from 2.1 D./F., 48,000 total denier cellulose acetate tow. Test rods from these runs which were made by the present invention showed that the filter elements had a weight of 0.4975 gram and a pressure drop of 11.9 inches of water and gave a removal of at least 31%. These filter ele ments of the present invention were compared with rods designated BN produced by prior art procedures from 2.1 D./F., 54,000 total denier cellulose acetate tow. The rod weight of these prior art type of elements was 0.5635 and the pressure drop was 11.9 inches of water. These rods made by the prior art, even though they were made from a bundle of filaments of some 6,000 greater total denier gave only a removal of 28%. In both instances the rods were each 247 mm. in circumference and 60 mm. long.
  • Example III In accordance with this example filter elements designated 4 PN were produced in accordance with the present invention by passing 2.1 D./P., 40,800 total denier cellulose acetate tow through the aspirating jet of the present invention into the forming means. .
  • the formed rods had a weight of 0.631 gram. Since the purpose of this particular example was to compare the hardness of the filter ele ment the rod produced by the present invention was tested and found to have a hardness value of 8.1.
  • the hardness of a filter rod is determined by measuring the transverse compression of the rod under a sudden ly applied load of specified magnitude.
  • the rod is placed lengthwise on a flat platen and centered under a vertically positioned anvil.
  • the anvil is one-half inch in diameter and has a flat end which is parallel to the platen.
  • the anvil is brought into very light contact with the rod.
  • the anvil is then suddenly released and allowed to press down on the rod.
  • the movement of the anvil is measured in units of 0.1 mm. and this measurement is the hardness value.
  • the total weight of. the anvil is 347.5 gr. Since the rod continues to compress at a decreasing rate with time, the measurement is made seconds after the load is applied.
  • rods designated 4 QR were produced by the prior art procedure from the same kind of filaments, namely 2.1 D./F., 40,800 total denier cellulose acetate tow. These prior art rods weighed 0.6185 gram and exhibited a hardness value of 12.5 when tested in the same apparatus and by the same method as just described. All of the rods tested were 24.7 mm. circumference and 90 mm. long.
  • Example IV A cellulose acetate tow of 3.2 D./F.-78,000 total denier processed in the conventional manner produced a 90 mm. rod weighing 1.066 grams. A mm. tip removed 36% of the smoke solids. When processed with the aid of the aspirating air jet, the 90 mm. rod weighed 1.096 grams and a 15 mm. tip removed 41% of the smoke solids. This increase in removal was effected with less than 0.3 in. additional pressure drop for the tip.
  • This invention can be used to form filters from fibrous or filamentary materials other than cellulose acetate as shown by the following examples, although the crimped continuous cellulose ester filaments represent the pre ferred embodiment.
  • Cotton sliver was prepared by conventional carding and drawing operations to form a sliver weighing grams per yard. This sliver was fed to the forming and wrapping unit without my invention and formed into rods 90 mm. long by 24.7 mm. circumference. These rods weighed 0.91 gram per rod and had a pressure drop of 9.0 inches. Another similar sliver but weighing grams per yard was processed in the same manner, yielding rods weighing 1.02 grams per rod and having 10.8
  • a tow comprised of polyester filaments, 0.7 D./F., 28,000 TD, 30 crimps per in. was processed without the use of the aspirating jet.
  • the resulting 90 mm. rod had a pressure drop of 10 inches and a 15 mm. tip attached to a 70 mm. tobacco portion removed 43% of the smoke solids.
  • the rod weight increased somewhat, the pressure drop of the 90 mm. rod increased to 11.1 inches and a 15 mm. tip removed 48% of the smoke solids.
  • An increase in removal of this magnitude would not have been obtained by increasing the total denier of the tow enough to give the same pressure drop when making rods without the aspirating air jet.
  • the present invention will successfully process filaments, for example, crimped 25 crimps per inch whereas the prior art processes were not successful in handling such type of filaments due to excessive breakage of the filaments. Therefore, the present invention will function satisfactorily not only on filaments heretofore used in the manufacture of filters but will operate successfully on finer more highly crimped filaments than heretofore have been regarded as practical for use.
  • jet is comprised of an inner member, the entrance endof which is more than twice the diameter of the exit of an outer member, said inner member being threaded into the outer member to provide an air chamber between the members, which air chamber exits internally close to the exit of the .smallerouter member.
  • a method of making a filter element from spread out crimped continuous substantially untwisted filaments which comprises passing a band of several thousand of said. spread. out untwisted filaments into a cone shaped jet positioned in close proximity to and at an angle to compacting and forming means, supplying a gas to the jet whereby the spread out filaments are motivated into and through the jet and thereby upon exiting from the jet are pushed into the aforesaid closely positioned compacting and forming means thereby beingvformed into the filter element, also supplying a filter element wrapping web to the forming means whereby the filter formed as aforesaid is Wrapped, sealing the wrapped webwaround the filter element and cutting the filter element to length.
