Abstract
Rod-shaped articles of the tobacco processing industry are advanced lengthwise in a conduit by a first air flow. Blasts of compressed air are admitted into the conduit behind successive articles to promote their advancement in a larger-diameter arcuate section of the conduit, particularly from a lower level to a higher level. The admission of successive blasts of compressed air is carried out by an open-and-shut valve which receives signals from an article detector located downstream of the valve.
