Method and apparatus for forming a stream from several types of tobacco

摘要

A tobacco stream which contains shreds and short tobacco is formed by moving an endless elevator conveyor with equidistant comb-like vanes first past a first magazine which contains short tobacco whereby the slender triangular prongs of the vanes remove and entrain batches of short tobacco and thereupon past a second magazine which contains shreds whereby the prongs of the vanes augment each batch by adding thereto an oversupply of tobacco shreds. A first paddle wheel with comb-like blades is adjacent to the path of the vanes to remove the surplus from successive batches, and a second paddle wheel serves to remove the surplus of shreds from augmented batches. Such batches are then converted into the stream which is trimmed by one or more knives which form short tobacco. The thus obtained short tobacco is fed to the first magazine.
