Braiding technology of open/closed loop knotless net design methods with diverse topological paths
To achieve open/closed loop knotless net braiding with diverse topological paths and avoid the interference of spindle in each direction with rotary braiding technology,a method of spindle arrangement representation was proposed.This method summarized the arrangement law and quantity relationship of the switch of open/closed loop knotless net braiding.Based on this principle,the arrangement scheme and running path of spindle can be designed based on the mesh and the open/closed loop state of the fabric,and the number of required switch can be calculated to realize the non-interference of the spindle in the braiding process and the braiding of open loop and closed loop knotless net with different mesh numbers.Coordinate transformation of spindle in braiding process combined with computer programming and graphics software,the physical modeling of braiding preforms with diverse topological paths was realized.By using the above method and principle,a knotless net braiding machine is designed and braided in practice.The results show that the method is feasible.Our research findings offer a valuable foundation for users to design knotless net braiding machines.
