ABSTRACT:
A continuous filter rod wherein dissimilar filter rod sections alternate with each other is monitored by a photosensitive detector which detects changes in the degree to which different sections absorb and/or reflect radiation. A pulse generator transmits signals for each unit length of the rod and such signals are multiplied and transmitted to several counters one of which ascertains whether or not the number of signals between two successive changes of the intensity of radiation is too low (this denotes that the length of filter rod sections of a certain type is insufficient), another of which ascertains whether or not the number of signals between two successive changes of the intensity of radiation is excessive (this denotes that the length of filter rod sections of a certain type is excessive), and a third of which ascertains whether or not the cutoff severs the filter rod at desired locations, e.g., midway across successive filter rod sections of a given type. Signals from the first and second counters are used to segregate the corresponding (defective) mouthpieces, and the signals from the third counter are used to adjust the filter rod making machine by changing the speed of that machine unit which assembles filter rod sections into a rod-like filler of the filter rod.
