Abstract:
An apparatus for separating foreign matter from a fiber containing material comprising:a) a first and second cylindrical toothed wire cleaning saws effective for releasably capturing fibers thereon, and both of said first and second cleaning saws being in revolving continuous contact with the same cylindrical doffing brush, wherein each of said cylindrical cleaning saws comprise a first grid bar and multiple additional grid bars effective for separating foreign matter from said fiber which is captured on said cleaning saws said second cleaning saw being positioned downstream of said first cleaning saw such that said first grid bar and said additional grid bars of said first saw are effective to generate a first waste stream comprising said foreign matter, wherein the majority, or totality of said first waste stream is directed onto said second cleaning saw which runs the waste stream through a steel roller to compress, embed, and regulate waste streams from the first cleaning saw onto the surface of the second cleaning saw and a second cycle of separation; b) means for the transfer of the fiber streams captured by the first and second cleaning saws to the doffing brush; and c) said doffing brush adapted to transfer the fiber stream to a lint duct.
