In the second part of the slider, slider’s body and size, is to pull the core position at the top of the head specimens and the head of the body cavity edge to the location of the relationship between bond Angle, the tooth chain will affect the meshing process, this is a 3 d, the relationship between tooth chain into time, pull the tooth chain speed, the Angle of metal zipper pulls head bang chain tooth mouth size effect, three coordination, eventually lead to chain the smooth degree of tooth meshing. But whether all dimensions are reasonable science, this is to need to be verified by theoretical formula, give reasonable explanation. The meshing and separation of the zipper should be explained clearly. The improvement of the quality of the zipper will require the guidance of scientific zipper foundation theory, which is the important reason to study the basic theory of zippers.
