摘要

A yarn-forming element is provided for a roving machine that produces a roving from a fiber structure using compressed air. The yarn-forming element includes an intake opening for fibers of the fiber structure, an outlet for emergence of the roving produced from the fiber structure, and a draw-off channel that connects the intake opening and the outlet. A front end surrounding the intake opening is formed as a first truncated cone in at least some sections thereof. The first truncated cone includes a larger base surface and a smaller opposite cover surface that is adjacent the draw-off channel. An angle (a) between a lateral line of the first truncated cone and an axis of the first truncated cone is less than 90° and greater than 70°.
