ABSTRACT:
The operation of apparatus for the production of composite filter plugs is controlled by a circuit which employs one or more capacitive detectors mounted adjacent to the path of filter rod sections and transmitting signals which are indicative of the passage of filter rod sections of different types and/or the absence of filter rod sections. The control circuit regulates the speed of the main prime mover which is directly coupled to a cutoff for subdividing the filter rod into composite filter plugs, the speed ratio of a transmission which can drive the conveyors of the apparatus at any one of several speeds, an ejector which can segregate defective filter plugs from satisfactory filter plugs, and the circuit for arresting the main prime mover.
