摘要
现代化的双向拉伸膜生产线速度已由８０年代的１５０ｍ／ｍｉｎ提高到３５０ｍ／ｍｉｎ，为适应这一要求，要求纵拉机能更精确的控制拉伸温度和拉伸倍数，本文对纵拉机预热、拉伸及热定型辊；工作辊的直径和排列；拉伸间隙；夹辊；张力辊；单点拉伸与多点拉伸技术；
The production speed of modern biorientated film production line has increased from 150 m/min of 1980s to 350 m/min,and to meet the requirement of this increase,the stretching temperature and multiple of machine direction orienter(MDO) should be well controlled.The preheating,stretching and heatset rolls,the diameter and arrangement of working rolls,stretching gaps,nip roll and tensile roll,technology for single/multiple points stretching,as well as the technical developent of broken film detector and transmission system are also introduced briefly in this paper.
