Abstract: The knot points, one of the component elements of fishing nets, can be divided into two types,namely knotted and knotless. The knotless nets can be further divided into layered and knotless warpknitted.The structural characteristics, applications and related knitting machines of different fishing nets are analyzed. The structure and performances of the machines for knitting knotted nets produced by different companies are compared, and the problems of these machines in practice are selectively analyzed. It points out that the basic structures of most existing machines for knitting knotted fishing nets are copies of Japanese-made ones in the 1970s and 1980s, with low speed and knitting efficiency. The author suggests improve the overall technological level of the machines by optimizing the design of the transmission systems and the structures of the driving parts, increasing the applications of photoelectric, mechanical, electrical,pneumatic, hydraulic and computer control technologies, integrating mechanisms with mechanics, and improving the manufacturing accuracy of parts and components.

Key words: fishing net machine; rapier loom; warp knitting machine; knotted; knotless
