    Abstract: A tension member for an elevator system has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member. In a particular embodiment, the tension member includes a plurality of individual load carrying cords encased within a common layer of coating. The coating layer separates the individual cords and defines an engagement surface for engaging a traction sheave. The individual cords are constructed of several strands and each strand is separated from direct contact with each other strand by polymeric material. While aspect ratios of greater than one are preferred, tension members of other ratios including round also benefit from the prevention of direct contact.

    Abstract: A non-rotating rope, comprising 3 or 4 strands of of clam-shaped cross section so arranged around a flexible core equidistantly from the rope center that the principal axes of the clams are on the equiangularly spaced radial lines radiating from the rope center and the sides of the clams are in contact with one another with the apex and base of each clam directed inwards and outwards respectively, is closed in a direction opposite to the direction of the lay of the strands.

    Abstract: The rope of this invention comprises a plurality of strands each having a twisted reinforcing fiber bundle, thermosetting resin applied to the fiber bundle, and a thermoplastic resin cover enclosing the fiber bundle. Each strand in the rope is kept to substantially a round sectional shape by the twisted fiber bundle.The method for forming the rope comprises the steps of twisting the reinforcing fibers in such a manner that the tensile strength of the twisted fibers is not reduced to less than 50% of the fibers not twisted, applying an uncured thermosetting resin to the twisted fibers, covering the fibers with a molten thermoplastic resin, cooling the thermoplastic resin to cover the fibers with solidified thermoplastic resin and thereby forming a strand, forming a rope structure from a plurality of the strands, and heating the rope structure to cure the thermosetting resin applied on the fibers.

    Abstract: The present rope is torsion free mainly because it has an inner rope formed by an inner layer of strands which is surrounded by an outer layer of strands and since the inner rope is constructed of at least three flattened strands and at least three round strands which are smaller than the flattened strands to fill the spacings between adjacent flattened strands. The inner strands surround a center member of elastic material.
