左压边激光测距装置12检测到压边完全收回后，打纬进入；此时纬线左边缘应完全进入压片7与织口8之间，压片7压下后，纬线左边缘因摩擦力被完全固定于机织物右边，以防下一次引纬时上一次的纬线被拉出；压边压下后右锁边气缸5活塞杆收回，打纬综框18复位，下一次循环开始。
进一步的，所述信号控制电路由AD采样电路21、信号处理模块22、微机处理器23以及驱动电路24；其中，所述AD采样电路21、信号处理模块22、微机处理器23和驱动电路24依次电性连接；所述箭杆激光测距装置9、左锁边激光测距装置10、右锁边激光测距装置11、左压边激光测距装置12分别连接至AD采样电路21。所述驱动电路24连接并控制步进电机1和各气缸的电磁阀。
所述激光测距装置9、10、11、12包括激光发射端31和光电元件接收端32。激光发射端31固定于各气缸上，光电元件32固定于各气缸活塞杆的顶端。激光行程检测装置9、10、11、12通过检测气缸活塞杆的运动行程后将数据发送给信号控制电路。当激光测距装置检测作为左右锁边、压边和引纬的气缸的活塞杆运动的行程，并将行程数据发送至信号控制电路微机中，由微机程序判断激光测距装置测得的气缸活塞杆的运动行程是否达到预设定的，如达预设定的值，则有微机控制下一步动作气缸电磁阀开合或步进电机的转动，从而使左右锁边压边及引纬装置能够做到无需剪断纬线的连续引纬。
