Abstract: The invention relates to a tobacco smoking article wrapper which selectively reduces the content of gaseous components in the smoke delivered during the use of the smoking article. The gaseous components can be low molecular weight aldehydes in the smoke produced during combustion/pyrolysis of the smoking article. The wrapper can comprise cigarette paper having an ammonium-containing compound filler therein for reducing the aldehyde content in the smoke. The ammonium-containing compound filler evolves ammonia upon combustion/pyrolysis of the smoking article which can chemically react with aldehydes in tobacco smoke and/or modify the combustion/pyrolysis reactions thereby reducing the initial formation of aldehydes to selectively reduce such aldehydes from the smoke inhaled by a smoker. The ammonium-containing compound can be magnesium ammonium phosphate used alone or in combination with one or more other fillers such as calcium carbonate.

Abstract: A cigarette includes an ignition element in contact with tobacco, surrounded by a composite outer wrapper. The outer wrapper is impervious to oxygen causing the tobacco to extinguish between puffs. The ignition element, however, has a longer static burn time than the tobacco and remains smoldering between puffs. Upon a subsequent puff, the smoldering ignition element re-ignites the tobacco. One or more initially-occluded perforations in the outer layer maintain the uniformity in combustion of the tobacco and ignition element.

The radiation which has penetrated through the web is measured by a photosensitive detector which transmits corresponding signals to an evaluating arrangement serving to ascertain one or more characteristics of the coatings.

Abstract: A tobacco product is formed by rolling a sheet of material supplied by a roll or rolls (e.g. moistened tobacco leaves) and/or homogenized sheet tobacco about a slit mandrel to form a shaped tube. The shaped tube is then packaged for shipment to an end user or consumer. The shaped tube remains in the rolled, shaped tube form inside the package.

A liquid can be added to the sheet or to the finished tube to moisturize same. The liquid can include flavoring. The tubes are unfilled when packaged and sent to a consumer/end user in tube form so that they have a “memory” that helps hold a tubular cigar shape after they are filled with selected tobacco fill material.
