In that state, spot welding is performed on the upper transverse line 92 and the lower transverse line 93. The shift base 42b at this time is
It is controlled to an intermediate position by the cylinder 42m. As shown in FIG. 7, the upper welding electrode 411 and the lower welding electrode 421 have vertical stripes 91 and horizontal stripes (upper horizontal stripe 92, lower horizontal stripe 9).
3) is provided at each intersection, and spot welding is simultaneously performed on the intersection using these welding electrodes 411, 421 ....

When this spot welding is completed, the grip portion 5
1 opens its movable bodies 51a, 51a, and the gripping portion 51 rotates in accordance with the contraction of the cylinder 53, as shown in FIG. 6 (E), and stops near the conveyor 7, and at that position, It waits for the inferior lateral stirrup 93 to be sent. Also,
When the spot welding is completed, as shown in FIG. 7, the horizontal bar gripping portion 81 of the drawing device 8 grips the upper horizontal bar 92 and the lower horizontal bar 93 after the welding is completed, and pulls the vertical bars 91 ... All together by the horizontal bar arrangement interval D. , So that the next welding point of the vertical stripes 91 is located at the predetermined position P (FIG. 6 (A)).

The wire mesh manufacturing apparatus 1 described above is an apparatus for manufacturing the wire mesh 9 having a double structure.
Can be used as an apparatus for producing a normal wire mesh, that is, a wire mesh composed of vertical and horizontal bars, instead of the double structure. In this case, the lower horizontal stirrup 93 is not supplied, but only the vertical stirrup 91 and the upper horizontal streak 92 are supplied by the above procedure, and when spot welding is performed, the shift base 42b is raised to the highest position, and the lower welding electrode 421 causes the vertical streak The spot welding may be performed in a state of directly contacting the lower end of 91 .
