- It should also be remembered that only 50% of the rapier movement is utilized in weft insertion, and, for single rapier looms, this wasted movement is also a time loss. 还应该记住，在引纬过程中，剑杆的动程只利用工作之了50%25，对于单剑杆织机，这种动程的损失也是时间的损失。
- It can be realized by reasonably setting the heald frame height of air jet loom by depending on the different form of the shedding and the different step of the weft insertion. 根据不同的开口形式及在引纬过程中不同的阶段对综框高度的要求，进行合理的综框高度设定。降低纬向停台，提高开台效率。
- The air index tester is an off line testing device simulating air jet weft insertion and measuring velecity of thr weft yarn(average and variation) in an air jct. 纱线气流指数仪是一种类似喷气织机引纬系统脱机操作的测试装置,用于测试喷气织造纬纱的速度(平均值和变异系数)。
- Steady weft insertion function:Adopting digital main nozzle, assistant nozzle, accessorial nozzle and big weft feeder, which guarantee Stability of weft insertion. 稳定的引纬性能:采用数字化控制的主喷嘴、辅助喷嘴、副喷嘴并用式和大储纬器机构。保证引纬的稳定性。
- In this paper, a matrix method is used to analyze the kinematic influence of structural-errors on the motion of beat-up and weft insertion system of a rapier loom. 本文用矩阵法分析了剑杆织机系统结构尺寸误差对打纬和剑头引纬运动的影响,建立了打纬和剑头运动两者的误差与系统各结构参数误差之间关系的矩阵方程。
- The advantages of a period of sley dwell to increase the time available for weft insertion and thus allow a higher loom speed to be achieved, are so obvious that the possibility of including a similar feature on a shuttle loom should be considered. 筘座的静止时间对增加引纬时间,提高织机速度的这一优点是如此之明显,以至于应该考虑是否让有梭织机也具有类似的性能。
- The future of this method of weft insertion would appear to lie mainly in the field of multi-color work, since their rates of weft insertion are generally only comparable with those of conventional automatic looms. 这种引纬方式的发展主要在多色织物领域,这是因为他们的引纬速度一般仅与常规自动织机相近。
- This reduction in the number of degrees of the pick cycle available for weft insertion is acceptable because the weft carrier does not have as far to travel as in the wider mechanisms. 这种减少引纬所占引纬循环角度的做法是可行的,因为载纬器不必像在较宽织机上那样穿行较长的距离。
- If the sley provides a means of guiding the weft insertion device through the shed, as in the Sulzer gripper loom and some flexible rapier looms, the sley must dwell in its most backward position during the whole of the time occupied by weft insertion. 正如苏尔寿片梭织机和某些挠性剑杆织机那样,如果筘座在梭口中能为载纬器提供一个导路,则当筘座运动到最后方位置并进行引纬的全部时间内,筘座必须处于静止状态。
