Abstract:

According to the principle of cut pile,a new kind of cut pile mechanism on tufting carpet loom was proposed.Based on the vectorial relations,the mathematical model of the hook-knife cut pile mechanism was established,which was used to make the kinematic analysis.Using the software MATLAB,the displacement, velocity and acceleration of each component were obtained and the motion law was given, especially the change curve of the loop-hamulus about its the angular displacement, angular velocity and angular acceleration curve.The method is simple and accurate, which calculate quickly and have considerably practical significance in the design of the cut pile mechanism on tufting carpet loom.

Key words: transverse jacquard, movement law, mathematical model, change curve
