Trimming control device for cigarette manufacturing machine

摘要

A trimming control device for a cigarette manufacturing machine is provided with a pair of rotatable trimming disks (20) having pockets (22) on their peripheral edges for trimming a shredded tobacco layer (TL) on a tobacco band (6), a detecting device (16) for detecting a filling density of the shredded tobacco in a tobacco rod (TR), and a control board (142) to which output from the detecting device (16) is supplied. The control board (142) makes a filling density distribution in the cigarette rod (DS) by sampling the output of the detecting device (16), extracts a peak zone including a peak from the filling density distribution, and determines a target cutting position of a tobacco rod (TR) at the central position of the peak zone.
