<p>A self-tightening sling for bracing a package of piece-goods comprises a loop-like supporting part (3) placed under the package and a loop-like closing part (4) placed on the upper part of the package (1), the supporting and closing parts being connected to each other through self-tightening knots (5) formed in the process of bracing by the ends of the loop-like parts located near the edges of the package. The self-tightening knot (5) is formed by the loop end of the closing part (4) which passes under the loop end of the supporting part (3), envelopes from outside one of the branches (6) of the closing part, then envelopes from outside the other branch (7), which is adjacent to the former branch, and comes outside in the upward direction from the loop of the closing part.</p> |
