<p>The system secures in position parallel or crossing belts, particularly for load-handling slings, by means of flat sheets of material. The belts (3-6) are inserted between two layers of the sheet material (2) in their desired positions. The layers (2) are then secured directly to each other, on either side of the belts, and they can be joined together over their entire areas in contact. One layer can be air-permeable and the other non-permeable, the first being typically of perforated, and the second of non-perforated, plastic sheet, the sheets being transparent. Between the belts, the layers can form a baseplate.</p> |
