Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method and apparatus for bundling fences formed by intertwining a large number of folded wires with each other.

(Prior art) This type of fence is installed, for example, on the mountain side slope or valley side slope of a road constructed by excavating the slope in a mountainous area, thereby reinforcing the slope and preventing rockfall accidents and road shoulder collapse. In order to transport the fence by folding it into a small size to the installation site, conventionally, as shown in FIG. The wires a are pulled out at predetermined intervals to form a fence A′ of a predetermined length (for example, 10 m), each wire a of the fence A′ is pulled together to reduce the length of the fence A′, and then the length of the fence A′ is reduced. After folding the reduced fence A° to a predetermined width in the reduction direction and bundling it,
As shown in FIG. 9(b), both ends of the folded fence A° are tied together with strings 3.

(Problem to be Solved by the Invention) In the conventional bundling method described above, when the fence A" is reduced, the intertwining between the wires a becomes loose, so even if the fence receives a slight impact during folding, etc. That wire a
easily rotates and shifts to the side (as shown by the imaginary line in Figure 9), or easily gets entangled with wire a other than the adjacent wire a.
Furthermore, when extending the fence A' at the installation site, similar positional deviations and entanglements are likely to occur, and it takes time and effort to restore the fence to its original normal state.

Furthermore, the above-mentioned bundling work is said to be difficult to mechanize due to the above-mentioned drawbacks, and is entirely performed by hand, resulting in low work efficiency.
