Safety net

Abstract

A method for producing a safety net, to a safety net, and to the use of such a safety net for protection from avalanches, falling rock or timber, mudslides, earth flows, or for slope protection. In the inventive method, firstly at least a first net element and at least a second net element are individually produced, self-contained, from respectively at least one rope, and are arranged parallel to each other and at a distance apart in a longitudinal direction of the safety net to be formed. Then the two net elements are connected to each other with the aid of at least one connecting rope, wherein the connecting rope is guided between the first and the second net element such that a self-contained connecting net element is obtained.

         9 . The method as claimed in  claim 1 , wherein the first net element and the second net element are produced in identical construction in terms of their size and shape. 
     
     
         10 . The method as claimed in  claim 9 , wherein the first net element, the second net element and the connecting net element are produced in identical construction in terms of their size and shape. 
     
     
         11 . The method as claimed in  claim 1 , wherein the ropes of the first net element and of the second net element are guided such that each of the net elements thus produced has in the longitudinal direction of the safety net a plurality of rows of rope junctions and in a transverse direction running at right angles to the longitudinal direction of the safety net a plurality of columns of rope junctions, and
 the at least one connecting rope is guided between the first net element and the second net element such that a self-contained connecting net element having just a single column of connecting rope junctions, which column is arranged in the transverse direction of the safety net, is obtained.   
     
     
         12 . The method as claimed in  claim 1 , wherein the ropes of the first net element and of the second net element are guided such that each of the net elements thus produced has just a single column of rope junctions, which column is arranged in a transverse direction arranged at right angles to the longitudinal direction of the safety net, and
 the at least one connecting rope is guided between the first net element and the second net element such that a self-contained connecting net element having just a single column of connecting rope junctions, which column is arranged in the transverse direction of the safety net, is obtained.
