Reinforced netted sheet

Abstract

A reinforced netted sheet includes a first wire set and a second wire set intersecting the first wire set. Each of the first and second wire sets includes a plurality of spaced-apart coarse and fine wires. The coarse wires intervene the fine wires. The coarse wires of the first and second wire sets are welded to one another at intersecting junctures of the coarse wires.

I claim:  
     
         1 . A reinforced netted sheet comprising a first wire set and a second wire set intersecting said first wire set, each of said first and second wire sets including a plurality of spaced-apart coarse and fine wires, said coarse wires intervening said fine wires, said coarse wires of said first and second wire sets being welded to one another at intersecting junctures of said coarse wires.  
     
     
         2 . The reinforced netted sheet as claimed in  claim 1 , wherein each of said first and second wire sets has a plurality of pairs of adjacent coarse wires, each of said pairs of said adjacent coarse wires intervening every two groups of said fine wires.  
     
     
         3 . The reinforced netted sheet as claimed in  claim 1 , wherein each of said coarse wires intervenes every two groups of said fine wires.  
     
     
         4 . The reinforced netted sheet as claimed in  claim 2 , wherein each of said groups of said fine wires includes three of said fine wires.  
     
     
         5 . The reinforced netted sheet as claimed in  claim 3 , wherein each of said groups of said fine wires includes four of said fine wires.  
     
     
         6 . The reinforced netted sheet as claimed in  claim 1 , wherein each of said coarse wires of each of said first and second wire sets is formed from at least two fine wires that are close to each other and that are partially adhered along the length of said fine wires.
