Abstract

1,124,309. Making nozzles in spinneret plates. E. I. DU PONT DE NEMOURS & CO. 27 April, 1967 [28 April, 1966], No. 19462/67. Heading B3A. [Also in Division B5] In a method of making a spinneret plate having at least one nozzle beginning in an entrance hole and terminating in a capillary, the capillary is prepared by stamping the thickness of the plate remaining after fabrication of the entrance hole with at least two different punches, successive punches having lesser cross-sectional dimensions and increased effective lengths, the first punch being sized in cross-section for substantial correspondance with and having an effective length less than that of the eventual capillary, the last punch having an effective length greater than that of the capillary. The entry and transition lengths 18, 20 may be made in one or more drilling steps and finished with a countersink punch. The plate is placed on an anvil plate 26 and a first punch forms a first capillary portion. A second punch forms the capillary portion 34 and a slight protuberance (36), Fig. 5 (not shown) which is removed by abrasive paper. The plate 10 is then placed on a thin backup sheet 38 and a third punch forms the portion 40. In a second finishing step, a protuberance 42 is removed to present an orifice 24. The capillary portion is sized in broaching operations to the diameter of the portion 30, Fig. 7 (not shown).
