Abstract

The present invention provides a smoking article having a reduced ignition propensity by reason of one or more cross-directional bands of an adhesive applied to the paper wrapper of the smoking article. The adhesive may be one of a cigarette seam adhesive, a filter plug wrap adhesive or a tipping paper adhesive conventionally used in the manufacture of cigarettes. A cigarette maker is modified to include the adhesive applicator apparatus of the invention which applies the adhesive bands to the paper wrapper in an in line process.
