摘　　要：针对纺织企业在使用双侧剑杆织机时,由于引纬工艺参数设计和调节不当而导致的中央交接纬失误问题进行深入分析。理论研究和实际测试发现,双侧剑杆织机中央交接纬成功率的高低,不仅与剑头本身的结构、性能、引纬系统安装质量以及剑杆运动规律有关,还和引纬工艺参数的设置有关。给出两剑在中央合理交接纬纱的条件,即在静态(名义)交接冲程和静态交接重叠角均大于零的条件下,还应使动态(实际)交接冲程和动态交接重叠角均大于零。引入最佳交接状态和最佳交接区域的概念,指出引纬工艺参数设计的顺序和应该关注的问题。This paper investigates into the failures of weft handover at the center of the shed on a rapier loom with two rapiers,which are caused by improper parameter designs or adjusting.It is revealed from theory and experiment that the success chance of weft handover concerns not only the structure and performance of the rapiers,the installation quality of filling insertion equipment and movement of the rapiers,but also parameters set on the process of filling insertion.This paper puts forward the rapier′s condition required for proper weft handover.Under the premise that both the static（nominal） transfer stroke and the static（nominal） overlap angle are greater than zero,it is also required to keep the dynamical（actual） transfer stroke and the dynamical（actual） overlap angle greater than zero.The paper also comes up with two concepts,i.e.the optimum handover condition and the optimum handover zone,and points out the sequence and several important points on specifying the parameters on the process of filling insertion.
