  • Patent number: 4644679
    Abstract: A method of effectively connecting a fishing net without the necessity for tying each net mesh to the support rope prevents a tearing-off of the fishing net with consequent loss of the net. During the connecting operation, a number of pairs of depending ear portions are formed along the support rope, one after another, by inserting a first depending ear portion into the support rope to form a second ear portion. The net is hung from the depending ear portions. Each pair of depending ear portions are successively connected to one another, without tying the two together at any position on the support rope.
