FIELD: production of fibers, threads and films from polymers, metals and nonmetals (for instance, glass), particular, spinning from melts and solutions by extruding through the offered spinneret. SUBSTANCE: spinneret for spinning fibers and threads has body, bottom part and molding holes. Body is made in form of hollow cylinder or polygonal prism whose side bottom walls have through holes, and provided on the end faces, from one or two sides, are holes for supply of worked material inside the spinneret. Supply holes are directed square to molding holes that is directly into the spinneret, with direction of motion, for instance, polymer, changes through 90 deg. EFFECT: higher efficiency. 1 cl, 2 dwg |
