ABSTRACT:
Apparatus and methods are described for forming a composite member for use in making a smoking article. The apparatus comprises a forming device that comprises (a) an elongate structure having a curved inner surface that tapers from a larger proximal end to a smaller distal end, the proximal end of the structure being adapted to receive a support member and a layer of material which are fed simultaneously into the device, the tapering inward curved inner surface causing the edges of the fibrous layer to bend around the inner support member, and (b) a curved forming surface that causes a first edge of the material to fold over the support member while permitting the second edge to pass by the forming surface, the curved inner surface of the device further tapering to the distal end causing the second edge of the material to fold over the support member proximate to the first edge.
