The core of a cigarette is covered with a sheath made of material which does not generate any appreciable amount of smoke when the cigarette is sucked but burns when the cigarette is sucked. The material is made of starch, agar, gelatin or a mixture thereof.
Low sidestream cigarettes comprise cigarette rods not exceeding 20 mm in circumference. The cigarette rods comprise paper wrappers of a type which effect a sidestream reduction of at least 30% when used on rods of conventional dimensions.
There is provided a smoking article having a mouthpiece 9 and a rod of smoking material 12 wrapped in a wrapper 14. A rod 15 constructed of for example activated carbon is provided within the smoking material 12. Between puffs the smoking material extinguishes leaving the rod 15 smouldering. During each puff the smoking material is reignited by the rod 15.
Apparatus and a method for laminating patches to a base web accurately, and as efficiently as possible, are provided. Two webs are fed at speeds which are related as the ratio of the width of each patch to the separation distance between patches, the patch web moving more slowly. Patches are cut from the patch web and transferred to the other web while being accelerated to the higher speed.

A cigarette having a circumference of about 25 mm includes a rod of tobacco cut filler having a circumference of about 12.5 mm which is in turn circumscribed by an air permeable insulating material. The tobacco cut filler has a packing density of less than about 400 mg/cm.sup.3. The insulating material comprises a fibrous material (e.g., glass fibers), and has a radial thickness of greater than about 0.25 mm, and often greater than about 0.5 mm. The insulating material is in turn circumscribed by a paper wrapping material having a low air permeability (e.g., less than about 15 CORESTA units). The cigarette includes a filter element at one end. The cigarette yields low levels of visible sidestream smoke.

Cigarettes which yield low levels of visible sidestream smoke upon use employ an outer paper wrapping material including magnesium hydroxide, calcium carbonate and flax fibers. The outer wrapping material has an inherent permeability of about 10 CORESTA units. The wrapping material contains an amount of water soluble alkali metal salt sufficient to provide at least about 30 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt normally is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. The cigarettes also employ an inner paper wrapping material including carbonaceous material and/or tobacco.
