separated tufts of fiber uses a transfer cylinder intermediate a revolving open reel type structure mounted within a porous housing to separate a conveying air stream from tufts of fiber conveyed thereby and a toothed cleaning cylinder to separate air flow through said revolving reel from said cleaning cylinder such that air is not drawn through said cleaning cylinder into said porous housing application_number US 81375910 A description as shown in fig1 patent application ser no 12 168 497 depends upon the short dense teeth of the standard cleaning cylinders used in upland cotton gin lint cleaners to seal against the air partial vacuum in the housing surrounding the u201c high speed air separator cylinder u201d this vacuum is required to induce an air stream to convey the tufts of lint to the lint cleaner fig1 taken from patent application 39 497 illustrates the housing around the sub atmospheric air stream entering at c and exiting at e it also shows the air seal formed between the short dense teeth at u201c 13 u201d and close fitting plate u201c 27 u201d preventing atmospheric pressure air from the trash removing grid area u201c 23 u201d being drawn into the incoming air stream c plate 28 also fits closely to the tips of the cleaning cylinder teeth to prevent air coming in at d from being drawn into the housing around the high speed air separator cylinder an improved apparatus and method according to the present invention is illustrated in fig2 wherein fiber tufts comingled with foreign matter are pneumatically carried by a conveying air stream c into the apparatus via an air duct 11 as is well known in the art fig2 is a cross sectional illustration of a preferred embodiment containing most of the features of the.
