INA-V型高倍牵伸装置的理论和实践

Theory and practice of INA-V High Drafting System

本文系统地分析了INA-V 型牵伸的机理、工艺性能和经济效益,并重点说明了高弹性,低硬度胶辊和气压摇架的使用性能,在肯定INA-V 型牵伸基础上,指出它的不足和改进方向。

This paper detailedly analysed the concept and drafting parameter,and also emphaticmallyexplained the use of top roller of high elasticity and low hardness and the' weighting arm forpneumatic loading.Teh system has given generally good results in practical operation whichprove its good peorformance and qualification in competition with general drafting system.Atthe end of this paper,it pointed out the development of the INA-Vdrafting system.
