摘要: Method and apparatus for recovering waste thermoplastic fiber of continuous length filamentary material and converting it into reuseable feed stock and particularly a large otherwise unmanageable, entangled mass of continuous length filamentary material, some or all of which being either drafted or undrafted, wherein the continuous length filamentary material is converted into random length staple fiber, the staple fiber is then mechanically compacted and melted into a melt flow, and the melt flow is finally extruded as the re-useable feed stock; and the resulting product of the method.
