Abstract

A tobacco rod firmness sensor arrangement wherein the tongue of a continuous rod type cigarette making machine is divided into an upstream portion and a downstream portion. The upstream portion is independently mounted from the downstream portion and is associated with a sensor to measure the force exerted by the tobacco rod compressed between the upstream portion and the garniture. Calibration of the sensor is unaffected by adjustment of the downstream portion of the divided tongue.
