引进帘子线初、复捻竖边钢领的消化与吸收

Digest and Assimilate the Imported Vertical Rings for Cord Twisting

本文运用环锭纺纱和加捻的基本理论,对日本引进专件——帘子线初、复捻钢领进行了力学分析,对竖边钢领的内跑道几何形状作了较详尽的理论分析和推导;用正交多项式回归的方法对引进钢领的“特定曲线”作了精确的测绘,并在国产同类竖边初、复捻钢领内跑道几何形状上首次用曲线取代直线,使国产竖边钢领在结构形式上有了重大的改进和突破。

With the basic theory of ring spinning and twisting the artic|e gives a mechanical analysis to the cord initial and repeat twisting rings, a theoretical analysis and deduction to the geometric profile of the inner running rail of the vertical ring. With the method of orthogonal and polynomial regression the author has very exactly meassured 'the specific cnrve' of the imported ring and first made use of such a curve instead of a straight Iine on the geometric profile of inner running rail of the counterpart product made in China, thus making a breakthrough in the structure of vertical rings of domestic make.
