Abstract: In order to reduce operator′s labor intensity,adapt to the quiet environment of sample fabric design office,and weave an acceptable sample fabric with smooth selvedges,a type of rope pulling magnetism shuttle weft insertion mechanism is designed in which filling operation is accomplished in such a way that the back and forth movement of the weft insertion shuttle with weft tube is performed by the attraction force of the magnetic shuttle.This design adopts the magnetic force actuation technology after analyzing the design request of the sample weaving machine and the characteristics of different weft-inserting ways.The cam drive in the groove is adopted for the weft insertion mechanism and computation method of the traction force of the magnetism shuttle is discussed.The new type sample weaving machine manufactures sample fabrics with smooth selvedges and makes very small noise.Other potential applications of the rope pulling magnetism shuttle weft insertion mechanism are also discussed.
