Abstract (en)
A nozzle plate for spinning has a plurality of spinning holes (4), each spinning hole (4) comprising a fluid-introducing portion (8) and a fluid-discharging portion (10) having a small inner diameter from which molten fluid sent from the fluid-introducing portion (8) is discharged. At least a part of the inner surface of each spinning hole (4), which is connected to an entrance (10a) of the fluid-discharging portion (10), is formed as a three-dimensional smoothly curved surface (9) so that a form line of the entrance (10a) of the fluid-discharging portion (10) substantially does not appear. A portion causing residence of the molten fluid can be removed, thereby achieving an extremely smooth flow, and the pressure loss can be considerably suppressed. <IMAGE>
