Abstract
Apparatus for pneumatically conveying filter rod sections from a sender to a remote cigarette filter tipping machine has a first switching device which receives filter rod sections from a single outlet of the sender, a second switching device which delivers filter rod sections to a single inlet of the tipping machine, and at least two conduits connecting the switching devices. The first switching device can direct filter rod sections into the receiving end of either one of the conduits while establishing a path for the evacuation of piled-up filter rod sections from the other conduit. The second switching device can connect the inlet of the tipping machine with the discharge end of either of the two conduits while connecting the discharge end of the other conduit with a source of compressed air in the event of clogging of the other conduit.
