【摘要】 本文推导了纱线络卷到筒子两端时稳定性条件的表达式,并以目前两种典型的导纱规律为例,通过实际计算表明,筒子在卷绕到中等偏小的卷装尺寸时,绕到两端的纱圈已经开始滑移,其中圆锥形筒子小端的不稳定现象尤甚。本文得到的稳定性条件表达式及有关结论弥补了专著的不足,对于槽筒沟槽的设计有一定的指导意义。更多还原

【Abstract】 This paper derives the formulae of the yarn stability condition when wound on both ends of a bobbin package. After two typical examples are analyzed, it comes to the conclusion: when the package dimension is near the medium size, the yarn loop wound on both ends of the bobbin has begun to slip already. The phenomenon of the yarn loop instability on the small end of a cone package is especially prominent.更多还原
