Abstract: A method for packaging a wrapped, moisture-sensitive, cylindrically rolled film by positioning along an alignment axis, a wrapped, rolled moisture-sensitive film, a funneling guide, a tube, and an extendible rod that includes a support head. The method comprises the steps of extending the rod through the tube while simultaneously and while maintaining the alignment of the wrapped film, funneling guide, tube and rod, tilting the alignment axis from a first position to a second position such that the wrapped film enters and moves through the funneling guide, and the wrapped film contacts the support head of the rod, retracting the rod such that the wrapped film enters the tube through the funneling guide, and while maintaining the alignment of the wrapped film, funneling guide, tube and rod the alignment axis, tilting from the second position to the first position and retracting the rod from the tube.

Abstract: A filtering system for use in coextrusion apparatus, and particularly for removing carbon particles from a core extrudate of thermally degradable barrier material which has been preencapsulated with a preencapsular material. The filter includes a casing and a frame mounted to the casing. A coarse filter screen through which the component streams can flow is also provided. The coarse filter screen is mounted to the frame and is composed of a web of woven strands having a sufficiently small diameter so as to permit the preencapsulated core extrudate to pass through and emerge from the coarse filter screen without substantial mixing of the barrier material and the preencapsular material. The fine filter screen is supported by the coarse filter screen upstream of the coarse filter screen.
