Abstract
An apparatus and method for forming a smoking article rod is provided. A forming device is configured to engage a continuous stream of a smokable filler material with a first surface of a longitudinally-continuous web of a wrapping material, the web having first and second edge portions extending along the web, and a second surface opposing the first surface. A wrapping device is configured to longitudinally overlap the first and second edge portions such that the first surface about the first edge portion extends over the second surface about the second edge portion, to contain the smokable filler material within the web. An adhesive applicator device is configured to apply an adhesive material to the second surface about and longitudinally along the second edge portion, between the overlapped edge portions, prior to the wrapping device engaging the overlapped edge portions, with the adhesive material therebetween, to form a sealed seam.
