Then, by analyzing the traversing motion of the yarn which is controlled by the rotaryblades and guide board, the design principle of the guide board profile is presented.
通过对旋翼导纱机构导纱运动的分析，提出了导纱板工作曲线形状的设计原理。

The new dies developed can forge high-precision rotaryblades forsuperchargers and, when working under dynamic loads, have the features of goodhardness, small deformation and long service life.
Six kinds of rotaryblades with same tillage depth and same mounting Angle are designed which have the circular element scoop surfaces. The parameters of the scoop surface are discussed and optimized.
