Definitions

  • This invention is a modification to standard filter making machinery.
  • the standard machinery produces cigarette filters by taking the output of a tow processing machine to feed the input of a filter rod maker. If a spiral filter is desired, a spiral tongue may be present in the filter rod maker.
  • Thesing U.S. Patent No. 5,012,829 reveals a filter which also has three concentric layers, the Thesing filter differs in that the middle layer of paper is plugwrap that is used to stabilize the inner most material (Col. 5, line 19-24).
  • the Thesing patent adds flavorants to at least one component of the filter, and only chemical plasticizers and/or wrapping can be used to stabilize the filter. (Col. 2, line 5-12)
  • the purpose of the additional layer of plugwrap is as a stabilizer.
  • modifications can be made to the area between the tow processing machinery and the filter rod maker or to the tow processing machinery.
  • Five of the six embodiments described are modifications to the area between the tow processing machinery and the filter rod maker are provided. These five modifications incorporate three new elements: 1) a top source of paper and means to crimp it (hereafter “top crimper”); and 2) a bottom source of paper and means to crimp it (hereafter “bottom crimper”); and 3) a spiraling means of type one of ordinary skill in the art would know.
  • top crimper a top source of paper and means to crimp it
  • bottom crimper a bottom source of paper and means to crimp it
  • top crimper alone produces a first type of filter.
  • bottom crimper alone produces a second type of filter.
  • spiraling means in series with either the top crimper or the bottom crimper alone produces a third and fourth type of filter respectively.
  • apparatus embodiment E produces a fifth type of filter.
  • the sixth embodiment of the present invention described involves modifications to the AF-1 machinery.
  • This embodiment requires three other elements: 1) a source of paper and means to crimp it; 2) a top source of tow; and 3) a bottom source of tow.
  • the above three elements used in combination produces a sixth type of filter.
  • This sixth type of filter has three concentric layers, the inner most being tow surrounded by a layer of crimped paper and an outer layer of tow.
  • the present invention includes a filter comprising three concentric layers, in which the intermediate layer is crimped paper that is not used to stabilize, but rather as part of the filtration process.
  • the present invention particularly refers to the area between the tow processing machinery and filter rod maker.
  • FIG. 1 shows a first embodiment of the invention ("apparatus embodiment A").
  • a source of tow 1 is processed by conventional tow processing machinery 2 .
  • this is AF-1 machinery manufactured by Hauni-Werke Korber & Co., KG, Hamburg, Germany.
  • a source of paper 3 is located between the filter rod maker 6 and tow processing machinery 2 .
  • the paper 3 is fed through a crimping means 4 .
  • the paper 3 is crimped by crimping wheels. As the paper 3 passes through the crimping means 4 it becomes crimped paper 7 .
  • the crimping means 4 is located above the exit port 12 of the tow processing machinery 2. As the crimped paper 7 passes through the crimping means 4 , it is laid on top of the processed tow 8 as the processed tow 8 leaves the tow processing machinery 2 through the exit port 12 . This creates a combined tow/crimped paper material 9 .
  • a guiding device 5 directs the combined tow/crimped paper material 9 into a filter rod maker 6 .
  • the filter rod maker 6 is preferably KDF-2 machinery manufactured by Hauni-Werke Korber & Co., KG, Hamburg, Germany. In the filter rod maker 6 , the tow/crimped paper material 9 is processed into a filter by conventional methods known in the art.
  • FIG. 1 One option, in the filter rod maker 6 , is to surround the combined tow/crimped paper material 9 with overwrap 10 and pass it through a curing chamber 11 .
  • This option is represented by FIG. 1.
  • the resulting filter shown in cross section in FIG. 7A, has a central core of paper 3 surrounded by a layer of tow 1 and optional overwrap 10 .
  • FIG. 2 (“apparatus embodiment B”) shows a second embodiment of the invention.
  • a source of tow 1 is processed by conventional tow processing machinery 2 .
  • this is AF-1 machinery manufactured by Hauni-Werke Korber & Co., KG, Hamburg, Germany.
  • a source of paper 3a At the exit end of the tow processing machinery 2 , between the filter rod maker 6 and tow processing machinery 2 , is located a source of paper 3a , crimping means 4a and guiding device 5 .
  • the paper 3a is fed through crimping means 4a .

  • the crimping means 4a is located below the exit port 12 of the tow processing machinery 2. As the crimped paper 7a passes through the crimping means 4a , it is laid underneath the processed tow 8 as the tow 8 exits the tow processing machinery 2 through exit port 12 . This creates a combined tow/crimped paper material 9a .
  • a guiding device 5 directs the combined tow/crimped paper material 9a to a filter rod maker 6.
  • the filter rod maker 6 is preferably KDF-2 machinery manufactured by Hauni-Werke Korber & Co., KG, Hamburg, Germany. In the filter rod maker 6 , the processed tow/crimped paper material 9a is processed into a filter by conventional methods known in the art.
  • FIG. 2 One option in the filter rod maker 6 , is to surround the combined tow/crimped paper material 9a by overwrap 10 and pass it through a curing chamber 11 .
  • This option is represented by FIG. 2.
  • the resulting filter shown in cross section in FIG. 7B, has a central core of tow 1 surrounded by a layer of paper 3a and optional overwrap 10 .
  • FIG. 3 (“apparatus embodiment C”) shows a third embodiment of the invention.
  • a source of tow 1 is processed by conventional tow processing machinery 2.

  • the filter rod maker 6, contains a spiraling means 13 to spiral the combined tow/crimped paper material 9.
  • the spiraling means can be one of those known in the industry.
  • the tow/crimped paper material 9 is spiraled such that the resulting filter, shown in cross section in FIG. 7C, has tow 1 on the outside of the spiral.
  • one option is to surround the filter by overwrap 10 and pass it through a curing chamber 11 . This option is represented by FIG. 3.
