Abstract
A control system for a cigarette making machine to provide improved cigarette rod weight control by continual adjustment of a servo-positioned ecreteur knife at the tobacco supply vacuum belt of the cigarette maker. The servo is positioned by a dual mode control system wherein one mode is based on long term feedback of cigarette rod density, measured by a .beta. ray gauge and a second mode based on a high speed adaptive feed-forward control based on tobacco density on the supply vacuum belt measured by a pneumatic gauge.
