Abstract
Method and apparatus for producing discrete filter rods includes a first conveyor for transporting filter segments of given length in a downstream direction. Three counter rotating transfer wheels receive the filter segments between spaced apart cleats on the circumference of the wheels. The first wheel receives the filter segments from the first conveyor and transfers the segments to the second wheel which in turn transfers the segments to the third wheel. Filter segments between the cleats on the third wheel are deposited upon a second conveyor with plug wrap thereon in precisely spaced apart relationship. Granular adsorbent material is filled into cavities between the filter segments, and a garniture folds the plug wrap around the filter segments and the filled cavities therebetween.
