Abstract
Hardness variations in a tobacco filler rod are detected and corrected in a single operation in conjunction with trimming of the tobacco to provide a trimmed filler rod of uniform height and uniform hardness. The single operation detection and correction is achieved by using force-applying member to compress the tobacco to a greater or lesser extent immediately prior to trimming, the degree of compression depending on the compressive force applied and the resistance of the tobacco to compression.
