Abstract
An asymmetrical trimmer disk/paddle wheel apparatus for trimming tobacco from a stream or braid of cut tobacco in a cigarette maker comprises a pair of counter rotating disks with a plurality of pockets arranged to coact with one another to trim off excess tobacco and create densified regions at the filter and lit ends of a cigarette rod product made in the maker. The pockets are constructed with different widths and depths to provide densified regions of different densities and lengths at the filter and lit ends of the cigarette rod product. The cigarette rod product formed by the asymmetrical trimmer disk/paddle wheel apparatus has an improved density profile that minimizes rejects at maker speeds up to about 8000 rods/minute.
