Abstract
A coiled rope providing a securely coiled rope structure which, when forcefully uncoiled, gives rapid yet controlled deployment of the rope, and a method of so coiling the rope. The rope is wound about a central core member in sequential, adjacent, planar circular layers of approximately similar diameter, each layer consisting of a plurality of coils of rope of increasing size commencing from the central core member. Adjacent coils of rope in each layer and adjacent layers of rope are releasably adhered to each other by contact cement so that the rope will remain securely coiled in storage or until required for use, and then permit rapid yet controlled uncoiling of the rope. Such a coiled rope is useful in providing controlled pay out of rope, for example, between life rafts being air dropped to survivors in the sea, the rope being payed out sequentially coil by coil and layer by layer.
