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.
Claims15
A cigarette making machine including at least one suction transfer wheel for carrying the cigarette fillter stream towards a wrapper web, and a plurality of air guide vanes extending in approximately tangential directions towards the transfer wheel and being sufficiently closely spaced to define at least one air channel through which air streams pass along the vanes so as to arrive at the wheel with directions of motion approximately the same as those of adjacent parts of the filler stream carried by the wheel, the ends of the vanes adjacent to the transfer wheel being spaced from the outer surface of the filler stream on the transfer wheel so as to be out of physical contact therewith.
