Compared with the traditional method, this method simplifies let-off and take-up mechanism, improves automatic level and synchronous character of let-off and take-upmotion.
与传统的方法相比，该方法使送经卷取机构大大简化，自动化程度高，送经卷取同步性能好。

In most cases uniform pick - spacing is the objective, and we use a "positive" take -upmotion.
在多数情况下是以均匀的纬纱间距为目的的，在这种情况下使用积极式卷取装置。

Since there is no motion, the entrapped liquid will heat up, and eventually partial evaporation may take place, a condition which must be avoided.
