  • Patent number: 11945178
    Abstract: Equipment for forming a tubular rod of fibrous material comprises: a gathering station constructed to receive a continuous supply of fibres and to gather the fibres into a bundle as the fibres advance through the equipment; a divider arranged in the path of the fibres through the equipment and constructed to from a cleft along the length of the bundle as it advances through the equipment; a mandrel positioned in the path of the bundle of fibres in alignment with the divider and constructed to form the cleft into a passage through the bundle of fibres as the bundle of fibres advances over the mandrel; and a die constructed and arranged to cooperate with the mandrel to form the fibres in a tubular configuration around the mandrel.
    Type: Grant

  • Publication number: 20230415431
    Abstract: A die or die assembly for forming a bundle of fibres into a rod or tube includes a body defining a passage for conducting the bundle fibres through the die from an inlet to an outlet, a constriction in the passage having an entrance shaped to form the fibres of the bundle into a desired configuration as the bundle passes through the die, and one or more conduits through which a treatment fluid e.g. steam, for curing the bundle of fibres may be introduced into the passage, and wherein at last one conduit is arranged to discharge fluid in the immediate vicinity of the entrance to the constriction to facilitate passage of the fibres through the die and reduce the risk of blockage.

  • Publication number: 20200316880
    Abstract: Equipment for forming a tubular rod from a bundle of fibrous material comprising a mandrel constructed to form a space within the bundle of fibres; the mandrel includes a passage for delivering a treatment fluid to facilitate the formation of the fibres into a tubular structure as the fibre bundle as the bundle passes over the mandrel.

  • Publication number: 20200214338
    Abstract: There is described an apparatus for shaping a tobacco industry product, the apparatus comprising a shaping head configured to change the shape of a first end of the tobacco industry product. The apparatus also includes an actuator configured to move the shaping head and/or tobacco industry product such that the shaping head is brought into contact with the tobacco industry product in order to change the shape of the first end of the tobacco industry product. The actuator can be configured to move the shaping head and/or tobacco industry product in a direction substantially parallel to a longitudinal axis of the tobacco industry product. The shaping head can be brought into contact with a first longitudinal end surface and/or an inner surface of the tobacco industry product in order to change the shape of the tobacco industry product. Also described is a corresponding method of shaping a tobacco industry product and a tobacco industry product formed using the method.
