Abstract
The tobacco stream trimming apparatus of a cigarette making machine has one or more discs which are driven at a peripheral speed exceeding the speed of movement of the tobacco stream through the trimming station. This results in a pronounced increase of the quality of cigarettes, especially dense-end cigarettes, because the pockets which are provided on the discs for the making of dense-end cigarettes penetrate into the tobacco stream and leave the tobacco filler without affecting the distribution of tobacco particles. The discs are driven by the main prime mover of the machine through the medium of an infinitely variable speed transmission whose ratio is adjustable by a servomotor in response to signals which are generated by a device that monitors the density of successive increments of the cigarette rod.
