CIGARETTES

摘要

The invention concerns a cigarette having an externalheat-deformable, paper wrapper comprising a proportion of thermoplastic fibres or filaments, the peripheral conformation of the cigarette having been modified by the application of heat to the wrapper. The proportion of thermoplastic fibres or filament in the wrapper is suitably not less than 40% by weight. The modification of the conformation of the wrapper may have been such as to provide an embossed-pattern effect over a portion or portions of the surface thereof or to produce a groove or grooves extending around and/or along the cigarette. In the case of a tipped cigarette, the modification of the conformation of the wrapper may comprise such deformation of a tipping wrapper as to improve the grip thereof on the tip and/or cigarette or to form flats on opposite sides of the tip. The invention also includes a method for modifying the peripheral conformation of a cigarette in which the cigarette, which has an external, heat-deformable, wrapper comprising a proportion of thermoplastic fibres or filaments, and a heated forming means are relatively moved in contact with each other in a direction transverse to the longitudinal axis of the cigarette. If the cigarette moved in contact with the heated forming means is a double-length filter-tipped cigarette, a tipping wrapper enwrapping the full length of the filter element and a short length of each of the cigarette rods may thereby interattach the same.
