Abstract:
A method of forming a tubular rod of fibrous material from a plurality of fibres produced by a fibre supply module is disclosed. The method comprises gathering the fibres into a bundle by advancing them through gathering equipment including a forming cone that comprises a divider to form a cleft along the length of the bundle of fibres as it advances through the forming cone, positioning a mandrel assembly comprising a mandrel downstream of the forming cone to receive the bundle of fibres from the outlet of the forming cone and to form a central passage in the bundle of fibres, and adjusting the position of the mandrel relative to the forming cone to align the mandrel with the divider of the forming cone.
