Definitions

  • Synthetic fibers as is known, are conventionally made by extruding molten polymers through a plurality of very small openings of an extruding die.
  • each said flexible duct is provided with centering means arranged at said other end of said ducts, said centering means extending outwardly and engaging on the walls of said second openings, thereby centering said other end of said flexible ducts with respect to said second openings, and thereby holding said other end in a position axially aligned with said second openings, even if said end of said flexible ducts is not axially aligned with said second openings.
  • the method further comprises the steps of providing a first path for the first polymeric component said first path extending through said first openings and through the inside of said flexible hollow ducts, to be discharged from the latter and through the die openings, as well as providing a second flow path for the second polymeric component said second flow path extending through said second openings and about the outer surfaces of said flexible ducts, to be discharged from said second openings and through said die openings, thereby encompassing the flow of said first polymeric component passing through said die openings, thereby forming a sheath-core type of fiber or filament.
