Abstract
The pressure of compressed air in one or more nozzles which convert successive increments of a running tow of filamentary filter material into a rodlike filler in a filter rod making machine is regulated in response to variations in the speed of the filler. This ensures that the resistance which the filter rod sections offer the flow of tobacco smoke does not deviate from an optimum value when the speed of the filler is reduced below the nominal speed. The pressure of air which is admitted to the nozzle or nozzles is regulated by a variable-speed blower which compresses air preparatory to admission into the nozzle or nozzles, or by installing in the conduit or conduits for one or more nozzles a pressure regulating valve which is adjusted by a servomotor in response to signals denoting the speed of the filler.
