In the wide weaving machine, the difference of warp tension on two beams are reduced by using a differential gear train of let-off motion double beams (side by side).
在阔幅织机上，以周转轮系差速器作双轴送经的方法可以通过机构自动调节来缩小两织轴的经纱张力差异。
The difference of the length of the rest yarn can be overcome by the use of two sets of electronic let-off motion respectively used to control the let-off of two beams.
以两套电子送经机构分别控制丙只织轴的送经运动，是克服余纱长度不等的措施。
The above-said let-off motion can meet the requirement of weft on warp let-off, and more the let-off can be fine tuned as well, keeping constant tension of warp let-offs.
该机构不仅能满足织物纬密对每纬送经量的要求，而且能根据经纱张力的变化对送经量进行微调，使送经量和经纱张力都保持基本恒定。
