Apparatus for transporting a file of successive filter rod sections lengthwise from a sender (such as a filter rod making machine) to a remote receiver (such as the magazine of a filter tipping machine) has an elongated pneumatic conduit with a section-receiving end at the sender and a section-discharging end at the receiver. The speed of lengthwise movement of sections in the conduit is monitored by a sensor which generates signals serving to control the operation of a valve which can influence the speed of the articles by varying the effective size of an outlet for the escape of air from the conduit, and/or to control the operation of a valve serving to admit into the conduit air counter to the direction of advancement of the sections. The purpose of evacuation of appropriate quantities of air from, or of admission of selected quantities of air into, the conduit is to maintain the speed of the sections in the conduit within a desired range regardless of the number of sections in the conduit.
