ABSTRACT:
A spinneret pack comprising a filtration assembly and an outer ring surrounding the spinneret plate, when it is clogged with unprocessed plastic material, is preheated by induction heating to separate the outer ring by slight pressure in a first processing step, then a second induction heating treatment separates the spinneret plate from the attached filtration assembly. The spinneret plate, detached by gravity, has matter in the die holes carbonized by the second induction heating process, thereby simplifying a final cleaning process which will make the spinneret plate reusable in the synthetic fiber manufacturing process.
