27 Beeetingh (Van), N., & Co., Kahoyk, nearLeyden —Inventors and Manufacturers.

Rope, untarred, three-strand, and hawser laid, for ships’rigging; twisted in a concentric manner, with equaldraught of the yarns, by patent machinery invented byone of the exhibitors. By this process, as many yarn-conductors and tubes are made use of as there are layersof yam to be twisted into each strand. The result is,a more regular position of the yarns, in concentric layers,and a greater equality in the draught of the yams, eachlayer of yam being submitted to the pressure of a separatetube.

[By this process, the rope, in proportion to its size, orthe number of yarn layers of which it is composed, notonly acquires greater strength, but, at the same time, withan equal number of threads of the same yam, becomeslighter and of less circumference, as appears from anumber of experiments made by order of the Dutch Government, in 1845 and 1846. These experimentsproved that a 7-inch rope, manufactured by this process,possesses an advantage of 5 per cent, in weight and 10 percent, in strength.]
