It is the function of the let - off motion to control the warp tension, so, to achieve the required result, both the take - up and the let - off motions must be functioning correctly.
控制经纱张力是送经机构的功能，因此要获得理想的结果，卷取机构和送经机构必须正常工作。
Characteristics: Oil soaking CAM and connecting bar system; sinker with an eyelet to take unable-closed steel wire; let-off boxes control two rollers for positive let-off motion.
特点：油浸式凸轮连杆机构，地梳固定不摆动，带耳沉降片穿防闭钢丝，送经箱体分别控制二辊罗拉积极送经。
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。
