Abstract

A cigarette making machine includes at least one transfer wheel for transferring the filler stream onto the wrapper web, and air guide vanes extending in approximately tangential directions towards the transfer wheel. As a result, the vanes arrest any particles of tobacco which fly off the wheel, and air streams induced by the suction in the wheel tend to return the particles to the wheel with a forward component of motion.
