CORE OF UNTWISTED POLYPROPYLENE POLYESTER JACKET OVER POLYETHYLENE AMERICAN OWNS THE PATENT on this modern construction. MANUFACTURING COMPANY. INC. Noble & West Streets ?

SAN FRANCISCO JETKORE construction is available in ropes of SSR, PNX, PNX-Type T, polypropylene and MP (manila covered polypro) in 3 Strand (5" and up) and 8 Strand Square Braided (6" and up). You cannot ask more of a rope than JETKORE offers. But, to get JETKORE, you must ask AMERICAN. JETKORE? is composed of strands, each of which has a core of straight, un-twisted polypropylene fibers that have been compressed into a homogenous mass. What has JETKORE to offer that other ropes do not? Just this . . . ? LOWER COST because there is less weight for a given strength. ? GREATER STRENGTH... as much as 15% because of the small amount of void space in the core plus the fact that strength loss due to yarn twisting has been eliminated. ? LONGER LIFE because the core fibers are substantially parallel and do not cause internal nicking or "sawing ac-tion" when the rope moves during use. ? Pat. No. 3.380,243
