In the case of joining ropes together on board, we often introduce the various knots or bends as occassion calls when we have not enough time for splicing or there is no necessity for doing so. It needs for the safety of work that we know the slipping and the breaking strain of the joining part of ropes. Therefore we have been to examine their strength on various methods in joining fibre or wire ropes. This time we examined about knots and bends on manila or wire ropes in the same way of the last time, in the case of the various splicings. Moreover we investigated a variety of ways of putting a rope stopper.
