As shown in the figure, the binding wire 40, which is a metal elastic wire, is bent in a circular shape so that the superposed portion 42 The overlapping portion 42 forming the swing ring 41 is in close contact with the overlapping portion 42. When a reverse external force acts on the overlapping portion 42 in the downward direction, 42 are separated from each other. When the external force is removed, the overlapping portion 42 is restored to the close contact state by the elasticity of the turning ring 41 and the overlapping portion 42.

Therefore, in the binding operation of the binding line 40 and the upper web 22 or the lower web 21, the operator opens the binding line 40 around the overlapping portion 42 to open the vortex ring 41, The mesh line 22 constituting the mesh 22 or the mesh 21 is put into the orbiting ring 41 and the overlapped portion 42 is restored to the close contact state. (40) and the upper network (22) or the lower network (21).

Even when the binding wire 40 having the hook 43 at the lower end is applied to catch the lower web 21, the upper end of the binding wire 40 is finally bound to the upper web 22, 40, tension is maintained, so that the release of the binding wire 40 from the lower web 21 can be effectively suppressed.

When the lower binding step S22 is completed, the binding line 40 is bound to the upper web 22, and the overlapping portion 42 of the upper binding ring 41 of the binding line 40 is opened to form the upper web 22, An upper binding step S30 for binding the binding wire 40 and the upper web 22 is carried out by injecting the upper web 22 and the lower web 21 into the revolving ring 41. As a result, do.

7 is a perspective view showing a state in which the coupling line 44 is screwed with the coupling line 40 so that the coupling line 44 or the coupling line 44 And the entire binding line 40 can be stretched and contracted by rotating.

That is, the binding wire 40 is bonded to the coupling pipe 44, which is a tube whose inner diameter coincides with the diameter of the binding wire 40, in which a screw thread is formed at one end of the binding wire 40, The inner circumferential surface of the pipe 44 is threaded so that the binding wire 40 is screwed to both ends of the coupling pipe 44 and the binding wire 40 is inserted and protruded as the coupling pipe 44 rotates .
