The fourth chapter talks about the weft carrier, in this part, we mostly introduce the big gripper shuttle in the comparative way and not only analyze the structure but also analyze the stress of the fatigable parts. In the fifth chapter, the shuttle box is our research emphasis, we start with the design principle and analyze its structure and the logic of the action of the parts. The sixth chapter discusses the shoot mechanism, builds its theory model and analyzes its law of motion from the view of kinematics and kinetics during the wefting. And then, we can consider the hydraulically shoot mechanism and comprehend its principle and some special parts. Subsequently, the content is about the flying of a shuttle, because the course of the flying of a shuttle is very complex, it is necessary to study the shuttle according to mechanics and to analyze its course of motion and its change of speed from the view of energy.
