  • Patent number: 7562835
    Abstract: The invention relates to a method and a device for obtaining the continuity of the uniformity of the structure and density of a stream of transported loose material, particularly organic plant material, and particularly tobacco material. According to the inventive method, a previously loosened material is compacted during transportation between conveyors, then, the compacted material is comminuted to a form suitable for further processing, and at least one intermediate element, preferably a bracket (5, 6), and thereby also the stream of the compacted material, is vibrated directly before the comminution process. A device according to the invention comprises at least one intermediate vibrating element, preferably this being at least one bracket (5, 6), located transversely to the direction of motion of the material.

  • Publication number: 20070163606
    Abstract: A device for transporting and compacting comminuted materials, particularly organic plant materials, comprises belt conveyors, located convergently to each other. Transporting and compacting carriers are made from a material accepted for contact with food products, particularly with tobacco material. According to the invention, both belt conveyors, situated at an angle (?, ?), respectively, relative to the horizontal direction, are equipped with uniform, continuous and endless belts. Elements increasing the adhesion and preventing sliding between the driving rollers and the surface of the belt are located on the inner surface of the belts of both conveyors, i.e., on the side, facing the driving rollers, while elements increasing the adhesion, preventing sliding between the belt and the transported material, are located on the external surface of the belt.
