Definitions

  • the apparatus comprises a gravity feed hopper, into which is fed finely divided particulate additive, such as hydrated alumina, and provided at its lower or delivery end with an outlet opening covered by a screen of predetermined mesh through which the additive particles fall onto the horizontally moving band and also provided with a rotary brush mounted therein in such relation to the screen portion of the hopper that particles of the additive are forced downwardly through the screen by action of the brush bristles in contact with the upper surface of the screen.
  • finely divided particulate additive such as hydrated alumina
  • any lumps or agglomerates originally present in the additive as fed to the hopper are broken up by the shearing action of the brush against the screen and only individual deagglomerated or nonaggregated particles are permitted to pass through the screen with the result that the additive is continuously and uniformly deposited over the upper surface of the moving tow band.

Defensive Publication applications have not been examined as to the merits of alleged invention. The Patent Otilce makes no assertion as to the novelty of the disclosed subject matter.
PUBLISHED NOVEMBER 24, 1970 T880,009 APPARATUS AND PROCESS FOR OBTAINING UNIFORM DEPOSITION OF FINELY DIVIDED ADDITIVES ON THE SURFACE OF A BANDED CIGARETTE FILTER TOW James E. Harris, Bristol, Tenn. Tennessee Eastman Company, Box 511, Kingsport, Tenn. 37662) Filed Jan. 28, 1970, Ser. No. 6,611 Int. Cl. B67d 5/20; Golf 11/24 US. Cl. 222-56 7 3 Sheets Drawing. 16 Pages Specification Apparatus for uniform deposition of a finely divided additive on a banded crimped multifilament cigarette filter tow to be used in making a cigarette filter rod. The apparatus comprises a gravity feed hopper, into which is fed finely divided particulate additive, such as hydrated alumina, and provided at its lower or delivery end with an outlet opening covered by a screen of predetermined mesh through which the additive particles fall onto the horizontally moving band and also provided with a rotary brush mounted therein in such relation to the screen portion of the hopper that particles of the additive are forced downwardly through the screen by action of the brush bristles in contact with the upper surface of the screen. By delivering the additive particles to the tow band in this manner any lumps or agglomerates originally present in the additive as fed to the hopper are broken up by the shearing action of the brush against the screen and only individual deagglomerated or nonaggregated particles are permitted to pass through the screen with the result that the additive is continuously and uniformly deposited over the upper surface of the moving tow band.
