Method of and apparatus for dispensing tobacco portions
First Claim
1. In a process for dispensing individual uniform portions of fibrous tobacco material or the like, including the steps of supplying continuously said material as a fleece or web, forming a strand of uniform density, separating said strand into individual portions in a measuring chamber corresponding to the volume of one portion, the improvement wherein the step of forming said strand of fibrous material of uniform density comprises directing an air flow onto said web in the conveying direction of said web towards said measuring chamber and confining the broken up fibrous material downstream of the point of contact of the air flow with the fibrous material web to cause separated material fibers to back up at uniform density.

Abstract
A method and apparatus is disclosed for dispensing discrete portions of fibrous material, such as tobacco, which is supplied continuously in the form of a fleece or a web. The fibrous material is dispensed in discrete portions which are of a uniform density, by causing the fleece or web to be placed in a container. The uniform density is achieved by injecting air into the fleece or web stream to break up the web and form a uniform density strand by insertion of the fibrous material into the container. Once the container is filled, the strand is severed by a cutter.

6. An apparatus for dispensing individual uniform portions of a fibrous material fleece or web by forming a strand of material fibers of uniform density and dispensing individual portions of said strand, said apparatus comprising:
-
a tubular conveying section for said fibrous material, a measuring chamber mounted adjacent to the discharge end of the conveying section for positioning coaxially with respect thereto for receiving the leading end of said strand of uniform density fibrous material, a separating device for separating the contents of the measuring chamber from the succeeding portion of the strand of uniform density fibrous material, said tubular conveying section having an inlet end and means for conveying the fibrous material fleece or web into the inlet end of said tubular conveying section, the improvement comprising; compressed air nozzle means opening into said tubular conveying section in the direction of said measuring chamber such that the discharge of air from the air nozzles creates suction to cause said fleece or web to move from said inlet toward said outlet and said compressed air nozzles break up said fibrous material web and create within said tubular conveying section and said measuring chamber said fibrous material strand of uniform density. - View Dependent Claims (7, 8, 9, 10, 11)
