Abstract
The invention provides a process of producing a nozzle member for sucking and transporting a string of yarn having an inner diameter which varies along an axial direction of the nozzle member. The process comprises the step of drawing a pipe stock having a predetermined outside profile so as to transfer the outside profile in an axial symmetrical relationship to an inside profile of the pipe stock. By the process, a nozzle member can be produced readily with a high degree of accuracy.
