and (4) interpenetrating and beating two adjacent braided rope sections on the other beam to form a dead knot to obtain the square protective net.
Generally, the protective net is a flexible structure, and in order to be conveniently woven, a weaving frame is required to be arranged, and the weaving frame is generally a hollow frame with a frame, so that a weaving rope can be conveniently arranged and fixed on the frame, the position of the weaving rope is fixed, and a certain shape is formed. The step of arranging the braiding frame may be understood as a preparation step of braiding the protection net, and the step of braiding the protection net on the existing braiding frame may be performed, which is equivalent to the step of arranging the braiding frame having been completed.
The weaving frame with corresponding shape and specification can be generally arranged according to the shape and specification of the protective net. As an alternative, the weaving strands are arranged in a square, for example rectangular, so that a square protective net can be obtained.
The number of the knitting ropes is usually determined according to the size of the protection net and the size of meshes in the protection net, the determined number of the knitting ropes is usually folded in half to form two sections of knitting rope sections with two free ends and a fixed end in common, and the knitting ropes are usually hung on a frame of a knitting frame through the fixed end, so that the number of knots among the knitting ropes can be reduced, and the strength of the protection net is improved; as the strength of the knotted location is typically reduced after the braided rope is knotted.

When a row of meshes of the protective net is usually woven, starting from one weaving rope section at the outermost side, the weaving rope section at the outermost side needs to be wound on the vertical frame to be folded back, then sequentially enabling every two adjacent weaving rope sections to be mutually inserted at one half part of the vertical frame according to the height of the meshes in the longitudinal direction to form an inserting lock catch, and finally winding the weaving rope section at the outermost side on the other vertical frame to be folded back to form inserting lock catches which are transversely arranged at equal intervals in sequence, wherein the interval can be called as a first interval and is also equal to the transverse width of the meshes; then mutually inserting two weaving rope sections extending out of the same weaving rope at the position of the longitudinal height of the mesh to form inserting lock catches which are arranged in the transverse direction at equal intervals, wherein the interval is also equal to the first interval, and the distance between the longitudinal direction and the frame of the formed inserting lock catch can be called as the second interval and is also equal to the longitudinal height of the mesh; a first row of mesh structures is then obtained. The above weaving process is generally repeated to obtain a multi-row mesh structure. When the last row of mesh structures are woven, adjacent woven rope sections need to be crossed to form dead buckles, and meshes of a closed structure are formed.
As an alternative embodiment, Rn-2And Rn-1Interspersing R at equal length positions includesn-2From Rn-1Then passing R throughn-2And Rn-1Respectively folded back to Rn-1From Rn-2And the middle part penetrates through the lock catch to obtain the inserting lock catches which are mutually connected in a cross way.

Weave the interlude hasp that the rope interlude formed usually, can effectively stabilize the structure of mesh, form the structure of interlude hasp simultaneously and weave and have appropriate relative movement space between the rope for the protection network that has the interlude hasp structure becomes flexible protection network, and the interlude hasp can not reduce the self intensity of weaving the rope, and the buffering that moreover can be fine is woven the outside impact force that the rope received, improves the protective capacities of protection network. The weaving ropes are mutually inserted to form the insertion lock catch, and the insertion lock catch can be mutually inserted once to form a single cross lock catch, and can also be inserted for multiple times to form a multiple cross lock catch. The number of times the braided rope is inserted, and thus the structure of the insertion lock catch, can be determined generally according to the structure and shape of the mesh.
