Yarn forming piece

The invention relates to a yarn forming member for an air spinning nozzle, comprising: a spinning cone having a cone tip, the cone tip forming a first end face having an inlet; the channel body forms a second end face with an outlet, and the channel body and the spinning cone are connected with each other; in order to provide a yarn forming part which can be produced in a particularly inexpensive and simple manner, it is provided that the spinning cone has a section in the shape of a frustoconical body, and that the section has a through-hole which passes through the channel body and the spinning cone in order to communicate the inlet to the outlet. The through hole extends towards the second end face in a clearance mode at the increasing distance from the inner surface side of the through hole to the outer surface side of the channel body limiting the through hole in the radial direction. 本发明涉及一种纱线形成件，用于空气纺纱嘴，它包括：具有锥尖的纺纱锥，该锥尖形成具有进口的第一端面；通道体，其形成具有出口的第二端面，其中该通道体和该纺纱锥相互连接；通孔，其穿过所述通道体和纺纱锥以将该进口连通至该出口，为了提供一种尤其可以廉价
