ABSTRACT:
A cigarette rod making machine wherein the apparatus which supplies tobacco particles to the stream building zone at the underside of a belt conveyor is designed to prevent entry of fragments of tobacco ribs into the outer layer of the stream. This is achieved by directing fragments of tobacco ribs into that portion of the stream which is to form the core of the filler of the cigarette rod and/or by directing fragments of tobacco ribs into that portion of the stream which is removed by a trimming device ahead of the station where the thus obtained filler is draped into a web of cigarette paper. Absence of fragments of tobacco ribs in the outer layer of the filler reduces the likelihood of piercing the web of cigarette paper at the wrapping station. Advancement of fragments of tobacco ribs into those portions of the stream which are to form the outer layer or the filler can be ensured or assisted by the additional expedient of designing the classifying device or devices of the distributor in the rod making machine in such a way that they cannot advance the relatively heavy fragments of tobacco ribs along those sections of the path leading to the stream building station which convey particles for the formation of the outer layer of the trimmed stream.
