Abstract
There is provided in accordance with the present invention a spin pack for filaments that contains one or more electroformed plates. The invention additionally provides a process for producing a plate for a spin pack, which process has the step of electroforming the plate.
Claims19
A spin pack for forming polymeric filaments, comprising a spin plate and a plurality of stacked electroformed distribution plates, said electroformed distribution plates having apertures therein and arranged so that the apertures of adjacent electroformed distribution plates only partially overlap wherein polymer flowing through said stacked distribution plates is channeled laterally and vertically through said spin pack.
A method of making a spin pack for forming polymeric filaments comprising:
- electroforming at least three distribution plates and placing said distribution plates in a stacked, flatwise configuration, said distribution plates being electroformed having apertures therein and arranged so that the apertures of adjacent electroformed distribution plates only partially overlap and wherein molten polymer flowing into the stacked distribution plates from a first distribution plate is channeled laterally and vertically through the stack and exits through a terminal distribution plate;
- providing a top plate having a first outlet opening and a second outlet opening and placing said outlet openings in fluid communication with said apertures of said first distribution plate;
- providing a spin plate having at least one aperture and placing the at least one aperture of the spin plate in fluid communication with said terminal distribution plate.
