<p>The mine netting has knotted joints and is made up of longitudinal and transverse rods (10,20) assembled by welding. The rods overhang in at least one direction and the overhanging rod ends form a loop with the end bent above the rod and obliquely to it. The other netting ends form an eye in which the end of the rod concerned is parallel to the rod. The eye makes a triple bend and the loops make an angle (alpha) of less than 30 deg. with the rod.</p> |
