Abstract: An apparatus for controlling an amount or mass per unit length of a tobacco filler in a cigarette manufacturing machine by utilizing the interrelation between a characteristic of the tobacco filler, for example air-permeation, radiation ray-permeation or the like and the amount or mass of the tobacco filler. Variations in the characteristic are detected and converted into an electrical signal, which is then applied to a fluid pressure distributing means to impart up and down movement to a trimming means through a piston means thereby to remove surplus tobacco from the filler. The quantity of the movement or a displacement of the trimming means is converted into an electrical signal, which is then fed back through an electrohydraulic servo mechanism to regulate the operation of the trimming means. Accordingly, variations in uniformity of the filler can be reduced at a very high response speed through one control mechanism with a simple structure.
