Abstract
Methods and apparatus for applying liquid strands containing additives to cigarette rods. Liquid is extruded to form one or more strands that are applied to loose tobacco filler in the chimney section of a conventional cigarette maker. The liquid has a viscosity that prevents it from soaking through the tobacco and contacting the cigarette maker or the cigarette wrapper. Additives to the liquid strands include flavorants, burn inhibitors, and burn accelerators.
