  • Patent number: 3934918
    Abstract: A load lifting band with an overload indicator includes a junction for strip material which is particularly useful for joining the ends of a strip of material so as to form a closed band for lifting heavy loads. The junction consists of a pair of overlapping sheet-like sections provided with interconnecting parts. The interconnecting parts each include a plurality of slits and corresponding sheet portions extending from the general plane of the respective section, the sheet portions of one of the sections each cooperating with a pair of slits in the other section so as to prevent separation of the sections in response to a force tending to move the same apart. The slits in each of the sections are divided into two sets each of which includes at least two groups of laterally spaced slits. The number of slits in one group is greater than that in the corresponding other group.
