  • Process and system for monitoring a continuous element being incorporated within a cigarette filter
    Patent number: 7448991
    Abstract: A system and process for monitoring a continuous element being incorporated within a cigarette filter includes a light source and a photoresponsive device facing each other and on opposite sides of a measuring gap, and passing the continuous element through the measuring gap and detecting movement of the continuous element by the effect of the movement on at least one light beam present between the light source and the photoresponsive device. Individual lengths of the continuous cigarette filter rod being produced can be selectively rejected based on a determination of whether the continuous element has a break or a knot along its length.
