Abstract
Production of cigarette filter rod is controlled by monitoring the tow (12) or rod (18) to provide signals indicative of tow consumption rate and varying the composition of the rod in accordance with the signals, e.g. to maintain a constant proportion by weight in the rod of tow and a plasticizer applied to the tow by an applicator device (18). The tow feed rate or the plasticizer supply rate may be varied in accordance with the signals. The monitoring device may comprise a tow bale weight sensor (48), a rod scanning head (54), or a weight band (33,57).
