1·A controlling method for keeping tension constant about beaming machine is put forward.

提出了采用变频器实现整经机恒张力的控制方法，对该系统进行了设计分析。

2·By taking beaming machine as an example, this paper describes the methods that realize the constant tension control of pay-off and take-up reel of wire and cable by using general inverter.

以倒轴机为例，介绍了采用通用变频器来实现线缆收放卷恒张力控制的方法。

3·The machine has two touch-screens, for the warping carrier and beaming head-stock, with overall control from a PLC that sends the warping speed to the drive.

机器有两个触摸屏，分别用于整经托架和经轴头架，由PLC提供整体控制。整经速度由PLC向驱动器传送。
