    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.
