摘要：进一步叙述在离心力分量F_My不略去时钢丝圈平面空间位置，它在坐标平面x′Ay′上迹线u的倾角κ＞0，并且∠κ=∠δ；经实例计算,钢丝圈平面的位置角δ较小。但已说明了纺纱时钢丝圈外脚超前。钢丝圈平面在坐标平面y′Az′上迹线w的倾角χ表明它呈整体前倾，导致钢丝圈纱线通道高度减小。分析钢丝圈上纱作用点J的坐标比q/s得出，质心高度低、圈形小的钢丝圈前倾大，纱线通道小。至于钢丝圈外倾角τ，它是钢丝圈几何图形在坐标平面x′Az′上投影对于轴Az′形成的，可直接从动态图上测量得。指出：纺纱时钢丝圈外倾是不可避免的，其质心坐标c应由气圈纱张力及形状确定之；按τ和c/a算出的τ_0v将是角τ₀的最小值；角τ₀可从钢丝圈和钢领呈弧面接触，钢丝圈下腿圆弧半径须为r₁的条件确定；掌握“圈径”概念对钢丝圈和钢领设计和使用非常有利，应注意圈径长度A₀M₀≌AM_v，每只钢丝圈都有属于自己的圈径A₀M₀，其斜度和长度已被确定而成为技术特征数。

  Abstract:This paper explains the space position of traveler in spinning by considered eccentric-forceF_My,it take shape of line u and line w on the coordinate plane x′Ay′ and y′Az′ respectively.As regard to u the inclined angle κ＞0，∠κ=∠δ,and by calculation angle δ  is litter,but this shows that the outside edge of traveler must lead the inside edge.As regard to w the incline angle χ shows traveler tilt front ward,resulted in that the yarn passage height of traveler decreases.However to analysis ratio q/s  and value s at point J  the result as traveler tilt front ward big and yarn passage litter be referred to mass-center low and traveler-shapes litter is shown.As to angle τ being the shape of traveler on coordinate plane x′Az′ tilt outward referred to initial ordinate,it could be measured from the force-diagram.The obliquity of traveler shape is not able to avoid in spinning,then the value c must be obtained from balloon.According to the value τ and c/a calculated value τ_0v will be the minimum of angle τ₀.Angle τ₀ has to be obtained from the bottom arc radius r₁ on the traveler being in contact with ring by arcual surface,then should be to attend line A₀M₀≌AM_v.Every traveler posses a contained line  A₀M₀,its length and obliquity had been set,so it becomes technology feature data.This idea is very useful to profile and use traveler and ring.
Key Words:traveler；ring；position tilt；contained line；contained angle；spinning
