Abstract

A method of manufacturing cigarettes including the steps of establishing a succession of 2-up hollow plugs in alternating relation to 2-up tobacco plugs and wrapping same in a tobacco web and overwrap, severing the resultant continuous rod at mid points of preselected 2-up tobacco plugs and severing again to establish associated pairs of singular tobacco rod plugs, separating the members of associated pairs of tobacco rod plugs and placing 2-up filter tipping plugs therebetween, and subsequently wrapping the interposed 2-up filter tipping plug together with adjacent portions of the singular tobacco rod plugs and severing the resultant tipped structure into individual cigarettes. Also provided are cigarettes constructed in accordance with the novel method.
