ABSTRACT:
A trimming control device for a cigarette manufacturing machine is provided with a pair of rotatable trimming disks having pockets on their peripheral edges for trimming a shredded tobacco layer on a tobacco band, a detecting device for detecting a filling density of the shredded tobacco in a tobacco rod, and a control board to which output from the detecting device is supplied. The control board makes a filling density distribution in the cigarette rod by sampling the output of the detecting device, extracts a peak zone including a peak from the filling density distribution, and determines a target cutting position of a tobacco rod at the central position of the peak zone.
