Definitions

  • ABSTRACT The uniformity of cigarette filters formed from coherent webs of filtration material is improved by feeding of the web about a convex idler roll just prior to feeding of the web into the garniture of a cigarette filter rod maker, and preferably feeding the web from the idler roll to the rod maker along the axis of the garniture.
  • the present invention relates generally to the formation of improved aerosol filter rods, and more particularly to formation of improved cigarette filters.
  • the present invention is concerned with apparatus and process improvements which serve in the preparation of cigarette filters having improved uniformity.
  • the present invention resides in an improved feed means and method for conveying a coherent web of filter material to the garniture, or condensing funnel, of a rod maker which converts the coherent web into a cylindrical rod of filtration material which may be subsequently processed, e.g., by cutting to desired lengths.
  • FIG. 1 is a perspective of the present feeding systems and a coherent web being conveyed.
  • P16. 2 is a plan view of the feeding system and a web.
  • FIG. 3 is a side view of the convex roll of the present inventron.
  • Another object is to provide an idler roll of improved configuration.
  • drive roll 10 rotatable by way of a drive means not shown, withdraws filter web 12 from a suitable source of supply, also not shown.
  • the source of supply may be a roll, a bale, or a unit used in the production of the filter web, for example.
  • Web 12 is then conveyed around the surface of a freely rotatable idler roll 14 and into garniture 16 of a filter rod maker, not shown.
  • drive roll 10 and idler roll 14 are positioned in such a manner that the web travels in a Z path from the source of supply to the rod maker.
  • the rolls are also positioned such that the web contacts from one-fourth to one-half or more of the circumference of each roll.
  • rolls l and 14 are substantially parallel and that roll 14 is positioned such that a web traveling about the surface thereof will be fed along the longitudinal axis of the garniture.
  • idler roll 14 has a convex configuration, i.e., the diameter of the roll at the center will be from about one and one-half to two and one-half times the diameter at each end. As shown in FIG. 3, X is one and one-half to two and one-half times the length of Y. It is to be understood, of course, that lower or higher ratios may be employed with some loss in the advantages of the present invention being experienced. It is also desirable that idler roll 14 by a low inertia roll in order that insignificant drag will be exerted on the web and so that the speed of the roll will be readily alterable with changing web speeds. Ordinarily, the roll will be about 12 to 18 inches in length. However, any length equal to or greater than the width of the web being processed is satisfactory.
  • a coherent filter web was first conveyed about a drive roll such as illustrated drive roll 10, and then fed into the garniture of a rod maker at an angle by conveying the web about an idler roll positioned above the axis of the garniture. Results obtained are designated below as the control. Runs were then conducted using the Z-shaped configuration illustrated in the drawings with the idler roll on line with the axis of the garniture. Data was obtained employing a cylindrical roll, a concave roll and the convex roll of the present invention. Twenty-five sample rods having a diameter of substantially 8 mm. were taken from each run and pressure drop was determined. The results obtained are set forth in the following table.
  • coherent web as employed herein is intended to define sheets of filtration material which is not readily separable by transverse forces. Conventional filter tows are not within the scope of the present invention.
  • An apparatus for conveying a coherent filter web from a source of supply to a condensing means comprising a cylindrical drive roll and a freely rotatable convex idler roll, said drive roll and said idler roll being so positioned that a web material being drawn from a source of supply will pass in a Z" path about at least one-fourth of the surface of each of said rolls, and then along the longitudinal axis of said condensing means.
